I guess you missed the update on this. This was the original statement:
So they acknowledged upfront that there were some complications/hurdles that might prevent it, and then they later told us publicly somewhere (it might have been an AMA IIRC?) that they were not able to overcome some of those hurdles after all and were forced to abandon the attempt, and instead would just make this possible with the thermostat’s official room sensors. So you are correct that it is not coming for the climate sensors, though they did let us know up-front that was a possibility and then let us know when it became clear they weren’t able to overcome those hurdles. Still frustrating though. I was also really looking forward to that. I have a bunch of Climate sensors 
As someone who currently has and uses Matter devices, I was initially optimistic of this. I’m not 100% convinced of this anymore though. Let me share some alternate perspectives with the community in general (this isn’t all directed to you, but general info for those interested that I can refer/link other people to later) on why Matter may not be as revolutionary and game-changing as some people suspect and why A LOT of companies have been bailing on it:
- For one thing there are a lot of unmet expectations with Matter not living up to the initial hype and promises. One of the missing or underdeveloped promises include the multi-admin feature allowing it to work seamlessly across different platforms. This is still a total failure years after it’s officially launched and way behind schedule.
- It also has really terrible and limited device support so far.
- There are huge technical challenges related to memory and processing capabilities for devices to support it, making very few legacy devices backward compatible, especially for any producing lower cost devices. Matter devices are generally exponentially more expensive than other options.
- It’s pay to play and not technically true opensource since you have to pay a huge membership fee plus yearly fees and per device (model) fees forever. This can be unsustainable for many companies. Consider the following. How is a company that makes contact sensors supposed to survive with Matter? The company has to pay a yearly membership fee plus a PER DEVICE (model) fee to maintain approval to use Matter. Once they sell that sensor, it no longer brings in new income without a subscription, but they have to keep paying their extortion fees to the Matter consortium. What happens once they stop producing and selling that device model (ie: as they iterate and create newer, better sensors)? Now they aren’t even making new money on those sensors, but they still have to pay their yearly extortion fees to keep it certified, and if they don’t, then they must remove Matter capabilities. How does that make any financial sense for any company to support Matter? It doesn’t. After a few generations of different devices or EOL’ing old models for new designs, they will either have to cancel Matter functionality on all old devices or risk that asset draining their profit margins as they’re still paying for something that is only a harsh liability draining their money for no reason. This will cause lots of Matter products to basically be useless every few years. That is horrible, but it is what Matter is going to cause due to their pay to play extortion certification model. OR companies will have to plan for this in advance and jack up prices on products really high to take this into account for several years in the future. Basically, you have 2 possible outcomes…either EVERY Matter device comes with a mandatory subscription, you will just either have to pay it all up-front in the initial hardware cost being jacked up, or an ongoing mandatory subscription from some companies’ products, or just know that within a few years your device will likely lose it’s Matter capabilities when the company stops paying the consortium the mandatory extortion fee…I mean yearly certification fee. The point is that the pay to play structure and not being truly opensource leaves Matter up for potentially being long term failure when some future protocol that is TRULY open source with no pay to play requirements is ultimately adopted…but that is not likely any time soon. This issue alone is enough to have major doubts about Matter.
- As things have progressed, more and more companies have been back-peddling on their initial support. More than increasing support. It is a concerning trend. Each of them have different reasons/concerns, but in the end, more and more are back-peddling than are adding support. Adoption is extremely slow and remaining with high market fragmentation with fewer and fewer full commitments to the protocol. Many are opting instead to use alternative solutions that do not have as many of the above technical and financial challenges as supporting Matter would require of them. Companies can directly integrate with Alexa, Google Home, and Home Assistant relatively easily and virtually for free in the long term. Home Kit does have some financial and technical hurdles for support, but they are easier and more affordable than choosing Matter. Some of this is likely intentional from those companies (make it easier and more affordable to go through them directly instead of the more difficult and expensive route through Matter).

I suspect that in the longer term, Matter will eventually be replaced with a REAL open source standard that is fair and doesn’t have Pay-to-Play mandates. I actually wouldn’t be surprised if the ultimate decision in the long term comes from the Open Home Foundation.
And remember I currently use Matter and mostly kind of like the idea of Matter. I’m not a Matter Hater. I specifically bought the Skyconnect so I could use Matter on Home Assistant, and I have Google and Alexa Matter Thread Border Routers too…but it’s not quite as amazing as we were initially hoping. It still has a lot of potential, but it is also a HUGE disappointment and I would certainly not call it the reliable game changer it was promised to be. A lot of companies see the same thing and have concluded they can still thrive by focussing on their existing ecosystems and ensuring compatibility with the major smart home platforms already in use, and so many of them have been ditching matter, or at least still producing alternative models that don’t use Matter that are more affordable and not at risk of being made obsolete through financial extortion or continued through exponentially jacked up prices.
Anyway, I am in no way speaking for Wyze here. Wyze has actually promised that once the Camera libraries are finalized they will review/analyze the Matter requirements/libraries and decide how to move forward at that time. However, it is likely most of their older cameras and other devices will not be compatible with the memory and processing requirements to support the required libraries. It will likely require them to launch new models specifically designed to support Matter. But they will have to figure out the Financial requirements and how to continue support of the certifications for years to come, including when they stop making that model camera without making it a financial liability in the long term.
The Matter consortium has publicly stated that they are in the process of working out the camera libraries right now, and we’re hopeful there will be progress by the end of the year. I expect whenever that happens, Wyze will finally decide how to move forward. They may decide to build matter into some new devices, they may decide like other companies recent that it’s still not worth it. They may build a “matter bridge” to support some legacy devices that can’t support the official libraries, and they might not.
But my point is that regardless of whether they support Matter and the technological and financial hurdles/challenges/considerations it brings, I hope that at least after that, they will reasonably consider the alternative benefit of a direct integration with Home Assistant, which will allow them to do this free and the Home Assistant team might even HELP them build it. They already did so with direct Google and Alexa integrations, and IFTTT, so they are obviously not trying to be a totally closed and isolated ecosystem. They have made efforts to support some of the biggest/most-popular platform integrations. Home Assistant is the next biggest Wishlist they haven’t fulfilled at all yet, and even has more demand than Matter, so it should realistically be their next priority if they are living up to their “be friends with users” to listen to our feedback and desires. The community has overall voted highest on Home Assistant over anything else, including Matter, or basically anything else. The only 3 things voted higher than it have been either fully implemented (2 of them) or at least partially implemented (1 of them). So this is now the highest requested unfulfilled request.
This already exists for Wyze sensors BTW…though you have to connect them directly to Home assistant and no longer be able to use them on Wyze. I have more than a dozen Wyze sensors that work 100% locally on Home Assistant right now.
I know there has been some discussion of people finding a way to integrate Wyze sensors through the Wyze HMS hub by polling the Hub locally instead of polling Wyze cloud API. I don’t know the progress on that, but it would be awesome if they figure it out!
I have said some similar things and addressed this to some employees in the following thread. It was actually remarkably well received by the company as I outlined a lot of my concerns. I am actually pretty optimistic that they are committed to making improvements. The following post and thread is pretty long, but it is actually a very encouraging response (both publicly and privately) to some hard to hear feedback they received from me and others IMO. I have been extremely impressed:
