Matter - smart home connectivity standard (formerly Project CHIP)

I guess they could have opted for a less radical approach, like let him move it to another domain if they really didn’t want the brand to be used in the domain and allow redirections for a while. Or just change the style if they felt the site was “impersonating” the official website.

Just remembered the time 9to5Google was banned from Google Adsense for trademark violation.

Govee has released a couple of new floor lamps, and The model 2 is matter over Wi-Fi so should work out of the box with SmartThings without custom code. Some of the fanciest features will only be available in the Govee app, but of course one of the good things about matter is that you can use the same device with multiple platforms.

UK link:

Govee has lots of different models and only a few support matter at the time of this posting, so read product descriptions carefully.


I came back to this as I posted another question. I haven’t kept completely up to date with Matter, but my impression is that it has stalled and might even be risky hopping on at the moment. Does anyone have any updates on this thread, especially about the reality and success of Matter integration for Tuya devices?

I have moved your post to the detailed Matter discussion thread. If you read through this topic starting with the posts from December 2023 onwards, beginning with the one below, you should get a good sense of where things are right now. :sunglasses:

Matter - smart home connectivity standard (formerly Project CHIP) - #738 by jkp

Much appreciated. Having skimmed through it, I feel justified in my assessment of the current situation, i.e. that it is a mess and certainly not worth investing in for the kinds of things I am interested in. I realised I have a Tuya hub that I bought to install some Candeo scene switches. I think I will just get a cheap switch that I have found from AliExpress and see how it works. It is a simple two-gang rocker switch and only costs around £13/$16 so not the highest risk purchase.

Sometime when it’s convenient (I realize this is a secondary location for you), can you verify that you have some local voice control of those models through Alexa?

Alexa has offered this for Zigbee devices connected directly to an echo Zigbee coordinator, but then the devices can’t be paired to any other Zigbee hub. (I use this as my own “Plan B“ for a few devices in my home, enough to create a pathway from my room to the front door.)

But I keep seeing conflicting reports as to whether it works for matter over Wi-Fi devices or not.

And Amazon just says it works for “supported devices“ but doesn’t have more details.

I’ll be there the end of next week and will test again. I seem to recall using Alexa to turn them on/off. I have them connected to Alexa with Matter over Wi-Fi, but to ST through the cloud-cloud integration since I have no ST hub at that location.


I know Alexa can turn them on and off when they’re connected by a matter, I just don’t know if it can still do it if you are not connected to the Internet. That requires the voice commands to be processed locally on your echo device. It’s doable for some devices, including matter over thread, I just don’t know if it works with matter over Wi-Fi.

So, let me preface the results of my testing by saying that my results may be skewed by the fact that I have Wi-Fi from my ISP’s router (AT&T FIber) and I noticed that my phone Wi-Fi showed as unavailable when I unplugged the fiber from the router. I suspect that the integrated Wi-FI works differently than if you have a Wi-Fi network that is independent from your ISP. So, I don’t know if local Wi-Fi communication is actually disabled/possible when the ISP router thinks the Internet is “down”.

That being said, I performed the voice tests in two different scenarios:

  • Using the ISP router’s “Disable Wi-Fi for device”
  • Unplugged the fiber from the router

In both scenarios, neither of the Leviton switches responded to voice commands without Internet available and Alexa announced “Something went wrong. Internet is not available”. Strangely, one of the dimmer/switches did respond in both scenarios, but not on the first attempt after using the “Disable Wi-Fi for device”. I can find no obvious difference between the two devices and both are in the same great room area where my ISP Router/Wi-Fi are located.

So, I’m not sure that my testing actually tells us anything about local execution since 1) one of the devices did respond; and 2) I can’t confirm the behavior of the Wi-Fi when the ISP router believes the Internet is “down” and/or the fiber it not connected.

What my testing does suggest is that you should probably have a Wi-Fi network that is independent from your ISP router to insure that local communication is available when the ISP router thinks the Internet is down. I can’t test that theory at my second location since it relies on my ISP and my primary location uses the Wi-Fi from the ST Wi-Fi Mesh Hub which requires Internet connectivity, even for local communication.

Hope this somehow helps :slight_smile:

Google Nest Thermostat with Matter

I purchased a new open box Google Nest Thermostat at the Thrift Store for $21. It was manufactured in 10/2021 (pre Matter), hardware version 1.4 and Software version 1.3.

After I paired it, I opened settings and was surprised to see there was a Linked Matter Apps and Settings. So Google must have added Matter to this device with an update. I gave it a try and was able to link it to SmartThings and Alexa with Matter.

I do have a Google Nest Mini which is probably needed for starting this process in Google Home. And I also have Echo devices which would be needed for the Alexa Matter integration.

So you can link it to SmartThings by the old cloud to cloud (c2c) method and Matter (If you have a ST hub).

The c2c method exposes more capabilities.

The Matter method is missing both Humidity and State.

The c2c method is NOT exposed to 3rd party apps sure as SharpTools, API Browser+, Alexa, etc.

The Matter device is Local and is exposed to SharpTools, API Browser+, Alexa, etc.

You can use both methods to get the best of both.


If you’re feeling ambitious, you could fork the ST repo and create a version of the driver to include those capabilities. :slight_smile:

That has crossed my mind. I really can’t believe that state was not included.


The aqara m3 hub is now available globally. You’ve probably already seen some news on it: my Home Automation feed this morning was full of bloggers talking about it.

My first edit of this post was incorrect: it is both a matter controller and a matter bridge, so that’s excellent. It means if you are using this hub, you can use it to bring many third-party matter devices into the aqara app and you can also use it to bring many aqara Zigbee devices into the SmartThings app.

It does not as yet appear to bring aqara Wi-Fi devices like the Fp2 into SmartThings, though. :thinking:

Note the following from the product page:

  1. Third-party device support is limited, only covers selective brands, and will be improved over time

As an example, on the release date, it did not support nanoleaf devices via matter.

Also, at time of release its matter bridge is very limited in terms of IR devices: it can only bridge one IR air conditioner. No other IR devices of any device class. In contrast, the SwitchBot hub 2 can bridge multiple IR devices of a number of different device classes.

But historically, aqara has been very good at adding new features frequently overtime through firmware updates, so it may get better. But no promises.

Technically, they are doing some brilliant stuff with multi hub networking, but most people won’t care about that, it’s all under the hood.

One caveat: the always thorough HomeKit News site reported that adding an M3 to their set up created intermittent instability for their thread fabric, but they also noted that might’ve been a matter of local interference. Other bloggers have not reported a similar problem yet, but it’s just something to be aware of.

HomeKit News offers links to the M3 at Amazon In multiple countries, including the US and the UK, along with a 20% off coupon code good through May 10, 2024.

Also note that Aqara uses “edge” the way the general IOT industry uses it: to indicate a server device with cloud connectivity, that also operates some functions locally. It is not a reference to the SmartThings edge architecture.

Lots of improvements to the spec, but of course, now the individual device manufacturers have to decide which, if any of those they choose to implement, and the matter controller manufacturers have to decide which if any they are going to support. And with an update schedule of twice a year, it’s probably going to be a while before we see many of these new features available for actual use. But it’s definitely a positive trajectory.

It will be interesting to see if any of the manufacturers adopt scene support, for example. :thinking:

Matter now supports scenes for product makers and smart home platforms to set, read, and activate for devices or rooms. Scenes let you create a desired state for devices, rooms, or your whole home by combining settings such as brightness or color in devices like smart lights that can be triggered with one command.



It’s really interesting, indeed. I would be more worried about them implementing it correctly and SmartThings exposing the feature too so it’s easy to use. Matter protocol for lights has SO many features, and almost none is exposed to the end user.

I’ve been testing Matter features in lights from Nanoleaf, WiZ and Tapo and they all have something basic that does not work as the specification says. Sometimes it’s the transition while dimming which is not smooth and continuous but harsh with visible steps, sometimes it’s a weird behaviour with low brightness levels, sometimes spamming the hub and making it sluggish, sometimes just commands that simply don’t work or ignore attributes like directions or times. Aren’t they tested to get certified?

Firmwares will fix it over time, but we’re talking about basic features since Matter 1.0 that weren’t even new since they were inherited from the Zigbee Cluster Library.

It’s going to be a slow ride to enjoy all the features as envisioned, but it’s quite promising and I’m all in. All my devices are already Matter, most WiFi but I’m even starting to have few Thread devices. Well, all except buttons, I stick to a certain brand with Zigbee because they’re cheap and I made a custom driver so I’m kind of locked-in :rofl:. Plus… there are almost no Matter buttons, the ones are quite expensive and I don’t even think they do bindings yet so there’s no advantage there right now.
