I just got my first Matter device (Kasa KP125M) to get familiar with this new protocol. It is an Energy Monitoring device and after fooling around with it for a few hours I can throw commands at it like on() and off() but power monitoring did not work... And then I found this post. I imagine if I use a non-Matter driver for Kasa it would work but I wanted to do it the "Matter" way! Has anyone been able to implement a handler for power monitoring in which the driver is Matter?
It looks like power monitoring was part of Matter 1.3 released in late spring. Iām not sure if Hubitat has implemented the new features or what version HE supports. Might be a question for @bobbyD
For example...Tapo Matter plug seems to think it can report power, but doesn't using the built-in matter outlet driver, or the community Matter advanced outlet driver...power always reads zero.
I'm actually running into the same issue - did you find a solution to get power monitoring through the matter protocol?
I only found a driver that worked for the non-M version to provide monitoring. The M version I believe has a different protocol so the non-M drivers are not going to work. The Matter driver allows on() and off() but I believe I read that the monitoring stuff is available with the latter Matter version which I don't think Hubitat engineers have included yet (as of my posting). I decided to byte the bullet and bought the Zooz Zen15. Works great but it is BIG. It is for large appliances so it worked out for me monitoring my refrigerator. I also purchased the Zooz XSE44 temperature sensor and also VERY happy with it. I had trouble communicating to the frig area with other devices but the LR (Long Range) based Zooz devices worked really well for that and general functionality. Good Luck.
This is good news. I have currently a device named KP125M1 and the "type" is "Generic Matter Outlet". How do I get "tplink_plug_em" to appear in my types list?
Thanks

I just removed the driver that was matter based and deleted the matter device I created in Amazon Alexa. I then installed the Tapo Integration and its EM device. I then used the Mobile Kasa App to install the KP125M and then used the IP it reported to run the Tapo Integration App. The Tapo App did not find the device?? Any words of wisdom would be greatly appreciated.

After several attempts I removed the Tapo App and reinstalled via HPM and it now works great???!
I am looking forward that in the near future a standard Matter inclusion will allow EM to work. But thanks for a method in the mean time that allows me to use my KP125M.
