Please edit your report and ATTACH the diagnostics dump as requested, do not paste large amounts of logs or json into the ticket directly as it makes the entire report unreadable. Thanks!

Same issue - I have 3 of these so pls let me know if I can be of assistance. The matter server is able to get the endpoint details correctly, as @sdaltons1 states none of the controls or status reflect this data.

Same issue - I specifically bought this purifier, Matter enable Welov P200 Pro, as I wanted to have integration with HA and utilize routines based on existing occupancy states in HA. I can see on HA Matter Server there are clusters for Air Quality, Hepa Filter, and Fan Control, but the device has no associated entities for this information. I've also noticed that when joining to my Google Home's matter network, there are no associated controles or indications aside from a non-functional fan control % either. I contacted the OEM's support line and they mentioned something about IoT networks needing to add integration for air purifiers coming in June of this year, but I supposed this is just a boilerplate statement from their support lines. Please let me know if I can be of assistance as well.

[marcelveldt]

Please be aware that this is a super new device, based on an even newer iteration of the standard. Allow us some time to even implement it. For Air Purifier devices, sensor(s) should be discovered for the air quality.

HepaFilterMonitoring is not yet supported, that will take at least a few months.
Fan platform support is currently in the making, let's hope we can make it in time before the next HA release.

Thanks for the diagnostics dump @sdaltons1 - that helps us a lot to test the implementation.

Thanks for the feedback!

Totally understand on that. This device is just launched in April so no rush.

IMHO Air Quality and fan control are the most useful, filter life monitoring is a nice to have but the OEM's companion covers that.

Thanks for the update! As @domeng83 says, I'll be thrilled just to get the basic functionality.

Let us know if we can give any additional info.

[marcelveldt]

Fan control for this device is now in the HA 2024.6 beta - the Air Quality sensor will follow soon.

[domeng83]

Thanks all! I am new to the HA world but this experience and the interaction with the actual development team leading the charge has covinced me of the value in supporting Nabu Casa via annual subscription.

This was closed, but the lights are still not working as well as the control backlights.

And how is that an HA issue ?
Most vendors currently only implement the bare minimum of the Matter spec so many controls are missing.
Can you let me know if the device should report this and if yes, in what Matter cluster(s) ?
Do open your own issue, not respond to a closed one from someone else.

@johnhtx These aren't reported in the Matter cluster from the OEM. The HA team can't do anything until AiDot/Leedarson adds the controls. If desired, you should file a ticket with the OEM support teams first.

First off, I don't know how any of this stuff works and I am following and learning so you don't need to be rude.
You're telling me "how is that a HA issue" well how are people learning supposed to know where one ends and one begins.
It's people like you that make things harder and hostile. So chill with the attitude.

Thank you. I'll see what I can do. What would I need to say exactly or should I just quote that those are not included in the matter cluster?

Thanks for explaining. I'll see what I can do.
