My Comments

Desktop operating systems started using audio customisations since the late 1980s

From the late 1980s to the mid 1990s, regular computers and their desktop operating systems introduced various multimedia abilities including file-based audio recording and playback. This came along with various user-experience customisation options like background wallpapers and interface elements that can be set to a user’s preferred colours.

These functions came together in the form of the ability for users to determine what kind of sound the computer makes for particular events like the startup sound, error sound or new message notification.

This kind of customisability was extended in the 2000s with mobile phones supporting ringtone customisation including downloadable ringtones. This feature was seen as important as a way for people to know if it is their phone that is ringing when it rings.

But Google has added this kind of customisability to their Nest Doorbell which is a video doorbell that works via your home network and Internet. Here, they have started offering special ringtones for this product that people can use for particular occasions like Halloween, Thanksgiving or Diwali. This goes hand-in-glove with you decorating your house in particular ways for particular seasons.

These devices would support the seasonality of particular occasion thus allowing the customised sound to play for the duration of that occasion. This avoids the audible equivalent of leaving decorations up beyond the applicable season which can look tacky.

I most likely would see a lot of companies who sell network-connected doorbell / intercom systems start investing in ringtone customisations for these devices. This could include user-supplied ringtones usually in common audio file formats, enabling ringtones to be applicable for particular seasons or user-defined periods, or bringing in brands and talent to create custom ringtones.

You just never know what other “Internet-of-Things” devices and platforms will end up with user experiences that are customisable by the end-user in the same way that computers and smartphones have been customised by their users.

Where Wi-Fi HaLow fits in with other Wi-Fi technologies

Wi-Fi CERTIFIED HaLow™ delivers long range, low power Wi-Fi® | Wi-Fi Alliance

Wi-Fi CERTIFIED HaLow (Product Page)

My Comments

A Wi-Fi network technology that is being put on the map at the moment is Wi-Fi CERTIFIED HaLow a.k.a Wi-Fi Halow.

This network technology is based on IEEE 802.11ah wireless network technology and works on the 900MHz waveband. It is about long-range operation of approximately 1 kilometre from the access point and very low power operation that allows devices to run for a year on commodity batteries like a single 3V coin-size cell or a pair of AA-size Duracells.

The power requirement may be a non-issue for devices like HVAC thermostats that are wired to the heating system they control. But they may be an issue with devices like movement sensors or smart locks that are dependent on their own battery power. As well, the low power requirements that Wi-Fi HaLow offer could be of benefit towards devices that implement energy-harvesting technology like solar power or kinetic energy.

This low-bandwidth Wi-Fi specification is intended to complement the other Wi-Fi specifications used with your home or business network. But it is focused towards the Internet of Everything especially where the devices are to be operated across a wide radius like a farm or campus.

The network topography for a Wi-Fi HaLow network segment will be very similar to the standard Wi-Fi network. That is where multiple client devices link to an access point, but there should be the ability for a mobile device to roam between access points associated with the same Wi-Fi network.

Compared to the likes of 802.15 Zigbee, Z-Wave, DECT-ULE, Bluetooth LE and similar Internet-of-Things wireless technologies, this is meant to avoid the need for special routers when there is a desire to link them to IP-based networks.

This is because this technology effectively uses the same protocol stack as our Wi-Fi networks save for the layers associated with the radio medium. It also means that the same security, connectivity and quality-of-service protocols that are part of Wi-Fi nowadays like EasyConnect and WPA3 can be implemented in Wi-Fi HaLow devices.

At the moment, you would need to use a Wi-Fi HaLow access point to get any Internet-of-Things devices on to your network and the Internet. It may be a small device that plugs in to your existing home network router or network infrastructure. But a subsequent Wi-Fi access point or router design could have built-in support for this standard thus making it more ubiquitous.

The use cases being positioned for Wi-Fi HaLow technology would encompass the smart home, the smart building and the smart city where all sorts of “Internet-of-Things” devices are acting as controllers or sensors. It is also encompassing vertical use cases like agriculture, industry and medicine where sensors come in to play here.

At the moment, this kind of connectivity will exist as an alternative to Zigbee, Z-Wave and similar technologies especially where IP-level connectivity and functionality is wanted at the device. It may not have ready appeal in use cases where a direct connection to Internet-based technology may not be required.

On the other hand, a use case could allow for a “hub and spoke” approach to the Internet of Things where a device can connect to accessory peripheral devices using Zigbee or Bluetooth but link to the home network and Internet via WI-Fi HaLow. An example of this could be a retrofit-install smart lock which supports the use of accessory input devices like keypads, NFC card/fob readers and contact sensors.

Wi-Fi HaLow could be seen as a direction towards capable low-power long-distance wireless networking for Internet of Things, especially where direct Internet / LAN network connectivity is desired out of the application.

These Google Nest thermostats will be able to let you know if the heating or cooling is about to break down

Nest thermostats in the US and Canada can now monitor your HVAC system | Engadget

Behind the scenes with the new Nest Thermostat (Blog Post)

HVAC Monitoring from Google Nest (Support Article)

My Comments

Google has added a notification function to their range of Nest smart room thermostats to let you know if the heating or air-conditioning is failing.

This has been a side project of theirs as part of the main Nest Smart Thermostat effort but is now finished. It will be available not just to the latest Nest thermostats but also for older models installed in the US and parts of Canada. The functionality will only work with forced-air systems that we in Australia often refer to as “ducted” systems, most likely because they are the most common type of residential heating / cooling setup in the US.

The functionality detects anomalies in how quickly the home heats up or cools down to the temperature the thermostat is set at. For example, it will alert you if it is becoming colder or taking too long to heat up while the heating is actually on; or becoming warmer or taking too long to cool down when the air conditioning is actually on. This will usually highlight a failing air-distribution fan or the burner in a heating system not staying alight while needed.

As well, it monitors the HVAC system’s control circuitry to identify abnormal shutdown activity or whether it is actually on and working as intended. Here, it observes conditions where the gas-fired heating may intermittently fail to light up or stay alight for the duration of the heating cycle or the air-conditioning fails to start cooling or runs longer than expected,

You receive the reports via e-mail or the Google Home App or a “heads-up” alert can be indicated on the thremostat itself. In most cases, you will have to call out your HVAC technician to rectify the problem. The “early alerts” functionality can be of use if you have your HVAC technician service your system regularly so it is working reliably and safely for the seasons that matter.

At the moment, Google encourages the use of “Nest Pro” technicians who partner with them to supply and install the thermostats or the “Handy” tradespeople platform who partners with Google. This allows for you to book them to attend to your system at the times that suit you through these platforms.

Thanks to the use of standard heating/ventilation/air-conditioning wiring setups that the Google Nest thermostats use to interface with the heating and air-conditioning, there is no need for this kind of system-health monitoring to be dependent on the use of a particular brand, model or series of HVAC system. This factors in the reality that “durable” products like these systems are expected to last many years and there is the requirement to allow newer thermostats like these to work with the older systems that are still in service.

Here, what I am pleased about is the idea of Google allowing a smart thermostat to be able to alert you to your heating or cooling system being at risk of underperforming or failing to make it through the seasons that matter. Hopefully they will have this kind of functionality for other types of heating or cooling setup or available in other markets. I also see this as a direction for smart thermostats from other manufacturers to alert you to the state of your HVAC setup.

Network-capable GE appliances will be able to interlink with the Sonos multiroom audio platform for audio notification purposes

GE APPLIANCES BRINGS SMART HOME NOTIFICATIONS TO SONOS SPEAKERS TO DELIVER AN INTEGRATED SMART HOME EXPERIENCE (Press Release)

My Comments

Two companies have been able to build a smart-home partnership with their products and platforms without needing the blessing of Amazon, Apple or Google.

Here, Sonos who have a multiroom audio platform for their speakers and for the IKEA Symfonisk speaker range, has partnered with GE Appliances to provide some sort of smart-appliance functionality.

This will initially work appliances that are part of the GE Appliances SmartHQ building-supplied appliance platform but will work across all GE appliances that can connect to your home network. At the moment it may apply to GE-branded appliances available within North America or based on North American designs but adapted for local conditions. That is with fridges with ice-makers capable of turning large “whiskey-friendly” ice blocks, or ovens capable of roasting a large Thanksgiving-size turkey.

The functionality that will appear is to use the Sonos speakers for audio-notification purposes such as alerting users that, for example, the washing machine, clothes dryer or dishwasher has completed its cycle or the oven that you have set to preheat is up to temperature. It understands the nature of most “white goods” other than refrigeration where they are used to complete a process like washing clothes or dishes.

The classic example that most households face is a washing machine (and perhaps a clothes dryer) being used to process a large multiple-load run of laundry. Here the householder will want to know when the current cycle is finished so they can have the next load going with a minimum of delay.

What is being conceived here is that a multiroom audio platform can tie in with appliances without the need for either of these devices to work with a smart-speaker platform. Rather it is about the consumer-AV platform serving as a sentinel role for the appliances or fulfilling some other role in relation to them.

For these setups to work effectively, the industry needs to work towards using platforms like Open Connectivity Foundation and implement a device-class-level approach to integrating devices within the smart home. It then avoids certain vendors, usually Silicon Valley heavyweights, becoming gatekeepers when it comes to having devices work with each other in the smart-home context.

It then avoids the need for device vendors to strike deals with each other in order and implement particular software hooks to have any sense of interoperability within the smart home.

Smart speakers like the Google Home are the baseline for the new concept of ambient computing

Lenovo see smart displays as a foundation for ambient computing | PC World

My Comments

A trend that is appearing in our online life is “ambient computing” or “ubiquitous computing”. This is where the use of computing technology is effective part of our daily lives without us having to do something specific about it.

One driver that is facilitating it is the use of voice-driven assistant technology like Apple’s Siri, Amazon’s Alexa, Google’s Assistant or Microsoft’s Cortana. It has manifested initially in mobile operating systems like Android or iOS but has come about more so with smart speakers of the Amazon Echo, Google Home or Apple HomePod kind along with Microsoft and Apple putting this functionality in to desktop operating systems like MacOS and Windows.

as are smart displays of the Lenovo Smart Display kind

As well, Amazon and Google have licensed out front-end software for their voice-driven home assistants so that third-party equipment manufacturers can integrate this functionality in their consumer-electronics products. It also includes the availability of devices that connect to larger-screen TVs or higher-quality sound systems to use them as display or audio surfaces for these voice-driven assistants, even simply just to play audio or video content pulled up at the command of the user.

Lenovo underscored this with their current Smart Display products and the up-and-coming Smart Display products including a Lenovo Yoga Smart Tab which was premiered at IFA 2019 in Berlin. These are based on the Google Home platform and they were underscoring the role of these displays in ambient computing.

Another key driving factor is the Internet of Things which may be seen in the home context as lights, appliances and other devices connected to the home network and Internet. It doesn’t matter whether they connect to the IP-based home network directly or via a “home hub” device. These work with the various voice-driven home-assistant platforms as sensors or controlled devices or, in some cases, alternate control surfaces.

It extends beyond the home through interaction with various building-wide or city-wide services that relate to energy use, transport, personal security amongst other things.

The other key driver that is highlighted is the use of distributed computing or “the cloud” where the data is processed or presented in a manner that is made available via the Internet on any device. It can also include online services that present information or content at your fingertips from anywhere in the world. In some cases, there is the use of data aggregation to create a wider picture of what is going on.

What this all adds up to is the concept of an “information butler” that responds with information or content as you need it. This is underscored with ambient or ubiquitous computing that is not just a Silicon Valley buzzword but a real concept.

What does the concept of ambient or ubiquitous computing underscore?

Here it is the use of information technology in a manner that blends in with your lifestyle rather than being a separate activity. You interact with one or more of the endpoints while you undertake a regular daily task and this can be about showing up information you need or setting up the environment for that activity. It relies less on active participation by the end-user.

Ambient computing is adaptive in that it fits in and adapts to your changing needs. It is also anticipatory because it can anticipate future needs like, for example, changing the heating setting to cope with a change in the weather. It also demonstrates context awareness by recognising users and the context of their activity.

But ambient computing still has its issues. One key issue that is called out frequently is end-user privacy including protection of minor children when users interact with these systems. An article published by Intel underscores this in the context of simplifying the management of our privacy wishes with the various devices and online services through the use of “agent” software.

This also relates to data security for the infrastructure along with data sovereignty (which country the data resides in) due to issues like information theft and use of information by foreign governments.

Similarly, allowing ambient-computing environments to determine activities like what content you enjoy can be of concern. This is more important because you may choose particular content based on your values and what others who have similar tastes and values recommend. It can also lead to avoiding addiction to content that can be socially harmful or enforcing the consumption of a particular kind of content upon people at the expense of other content.

Another factor that can creep up if common data-interchange standards aren’t implemented is the existence of data “silos”. This is where an ambient computing environment is limited to hardware and software provided by particular vendors. It can limit competition in the provision of these services which can restrict the ability to innovate when it comes to developing these systems further.

But what is now being seen as important for our online life is the trend towards ubiquitous ambient computing that simply is part of our lives.

Use of a user-installable module allows these Yale smart locks to work with different connected-home systems

Yale Expands Assure Lock Line With New Smart Lever Lock | Z-Wave Alliance

My Comments

Yale have implemented the smart-lock approach in a very interesting way ever since that company released their Real Living Connected Deadbolt in to the North-American market.

Here, they designed an electronic lock as a basic platform device but built an expansion-interface arrangement in to this lock’s design. Here, users could install a retrofit module in to the battery compartment on the door’s inside to add on Zigbee, Z-Wave or August smart-lock connectivity to their lockset.

This approach has been rolled out to the Assure range of electronic deadbolt locks and lever locksets with the use of the same module type for the whole range. It also applies to the Lockwood Secure Connect product range offered in Australia which is based on the Yale designs.

A similar approach has been implemented in the UK for some of the Yale electronic door locks sold in that market. But the modules used with the UK locksets are different to the North-American modules due to the regional differences that affect how Z-Wave and Zigbee operate and the country’s preferred building-hardware form factors. One of these units is infact designed to replace the outside cylinder on a rim-mounted nightlatch or deadlatch to enable “smart lock” functionality to this common class of door lock.

All these modules are expected to be installed in a “plug-and-play” fashion where they simply add the extra functionality to the lock or bridge it to the smart-home ecosystem once you install the module. After you install these modules in the lockset, the only thing you need to do is to pair them with the smart-home or integrated-security ecosystem.

Even within the same form-factor, the electrical interface for these modules may be varied for later products which can raise compatibility issues. Similarly, some of the home-automation integrators tend to presume that a particular module will only work with their system.

They also work on a particular “Internet-of-Things” wireless interconnection rather than an IP-based home network, requiring them to use a network bridge to work with an online service. This bridge is typically provided as part of a security-and-home-automation ecosystem whether offered by a telco, security services firm or similar company.

What have I liked about this approach is the use of user-installable modules that are designed to work across a particular Yale smart-lock range. Here, these modules interlink with Yale or third-party smart-home setups with the ability to be replaced should you decide to move to a better home-automation system that uses a different Internet-of-Things interface.

It underscores the fact that, once installed, a door lock is expected to be in service for a very long time and this same requirement will be placed upon smart locks. This is even though new smart-home or smart-building technologies will appear on the horizon.

It is similar to how central-heating systems are being enabled for smart-home operation through the use of a room thermostat that has the “smarts” built in to it. These thermostats are designed to be powered by the host HVAC system and connect to that system according to industry-standard wiring practices that have been determined and evolved over a long time.

This approach can be taken further with other devices like major appliances that are expected to serve us for a long time. Even if a manufacturer wants to create an ecosystem around its products and accessories, it needs to keep the specifications for interlinking these products and accessories the same to allow users to implement newer devices in to the system.

It can also work properly with a self-install approach where the customer installs the necessary aftermarket modules themselves or a professional-install approach which involves a technician installing and commissioning these modules. The latter approach can also work well with manufacturers who offer “functionality” or “upgrade” kits that enable the use of these modules.

The ASSA Abloy approach to making sure your smart lock works with the smart-home system by using user-replaceable modules makes sense for this class of product. Here, you are never worried about the smart-lock ability being “out of date” just because you install a home-automation setup that suits newer needs.

What needs to happen with the retrofit approach is that the physical and electrical interface for add-on modules has to be consistent across the product range or device class for the long haul. There also has be be some form of compatibility should any design revisions take place. Similarly, using a common application-level standard can work well with allowing the same device and retrofit module to work with newer systems that adhere to the relevant standards.

These expectations may not really work well with system integrators, telcos and the like who prefer to be the only source for products that work with a smart-home system.

Here, it is the first time I have noticed a smart-home device designed to be upgraded over its long service life.

We could be expecting more from distributed-Wi-Fi devices of the NETGEAR Orbi ilk thanks to 802.11ax Wi-Fi and the Internet of Things

Distributed Wi-Fi: How a Pod in Every Room™ Enables Connected Smart Homes | Wi-Fi Now Blog

My Comments

The Wi-Fi Now consortium wrote up a blog article where we are to expect more from a distributed Wi-Fi installation especially in the context of Internet Of Things and the smart home.

One of the key drivers for this issue will be the 802.11ax standard for Wi-Fi wireless networks. This is intended to be the successor to the current 802.11ac but also is about high throughput and the ability for multiple devices to work at once from the same network. As well, it is expected to yield high-efficiency operation with an experience similar using an Ethernet network that uses a switch like when you have devices connected to your home network’s router via its Ethernet LAN ports.

According to the article, 802.11ax with its increased throughput is pitched as being suitable for newer broadband-service technologies like fibre-to-the-premises, DOCSIS 3.1 HFC cable-modem and 5G mobile broadband. In the context of the distributed Wi-Fi network, 802.11ax will be positioned for use as a wireless backhaul between the access-points and the edge router that links to the Internet.

But the article places an expectation on these access-point pods being installed in every room due to the increased number of Wi-Fi-based network-enabled devices connected to the home network. There is also an expectation that these access points will support Bluetooth and/or Zigbee as well as Wi-Fi thus becoming a localised network bridge for smart-home and Internet-Of-Things devices based on these wireless technologies. But I would place in the same scope Z-Wave, DECT-ULE and other similar “Internet Of Things” wireless technologies.

Previously this kind of functionality was offered through separate network bridges that interlinked a Bluetooth, Zigbee or similar-technology device to your home network via Wi-Fi or Ethernet.

Such equipment was typically offered as an accessory for a smart-home device like a smart lock by the device’s manufacturer and you weren’t sure if this piece of equipment would work with other smart-home devices implementing the same wireless-link technology. Or it was offered as a “smart home hub” which worked with devices using a particular wireless technology and supporting certain function classes. But these hubs offered various smart-home controller functions including remote management as long as you were using particular apps or services.

This new approach could allow for an increased number of IoT devices in each room “talking” with the access-point pods and this data moves along the backhaul to the “edge” router for that “smart-home-as-a-service” setup. The article also sees it as allowing for an IoT device, especially one that is battery-powered, not to be part of a large Zigbee, Z-Wave or Bluetooth mesh thus leading to increased device reliability. I would also see it become relevant with setups that use technologies like DECT-ULE which use a “hub and spoke” topology.

For this concept to work properly, the network-bridge devices that interlink Zigbee or similar IoT wireless technologies to an IP-based network have to work independent of particular smart-home controller software. Then the smart-home controller software has to be able to work with any IoT-based device no matter which of these network bridges they are talking to as long as they are on the same logical network. This situation would be of concern with portable user-interface devices like remote controls that are likely to be taken around the premises.

Although this article is Wi-Fi focused, I would still see the wired network being important. For example, some house designers and builders are even wiring the homes they design with Ethernet whether as standard or as an option while the home is being built or renovated. As well, there is powerline networking based on either HomePlug AV500 or AV2 standards. Here, these wired-network technologies are still viable as a backhaul connection alternative especially if you are dealing with building materials and techniques like double-brick or sandstone construction, or foil-lined insulation that can slow down Wi-Fi wireless communications.

But could these wireless-network access-point “pods” be simply a dedicated device installed in each room? It could be feasible for a device that offers other functionality that benefits from the network to be an access point or one of these “pods” in its own right. For example, a network-capable printer or a consumer-electronics device like a home-theatre receiver could connect to an existing network’s backhaul but also be an access point in its own right.  In this context, a Smart TV installed in a lounge area further down the end of the house could become an access point or smart-home “pod” to cover that end area.

The idea has been proven in the form of the Amazon Echo Plus smart speaker which has a built-in network-bridge function for Zigbee smart-home devices. This is alongside the ability for it to be a controller for these devices in context with the Amazon Alexa ecosystem.

What is being put forward with the Wi-Fi NOW “Pod In Every Room” concept is the idea of a single logical network with a high-speed wireless data backbone and access-point devices serving all wireless networking applications for both regular data transfer and smart-home/IoT applications. As long as the approach is driven by common open standards without dependence on particular technology owned by one vendor, then there is the ability for this approach to multi-function Wi-Fi networking to work properly.
