Can you post a screenshot of the debug logs that follow a refresh() command?
Merry Christmas! 
Please update to ver 1.0.2 2023/12/26 1:57 PM
There are a lot of changes in the code, including the use of the Basic cluster attr. 0 for the ping() command - I expect this method to work for all different Matter devices now.
I have also added 'Get Info' command. Click on it and observe the live logs page (it is better to run it with the Debug logging turned off). I am curious what will be the results with your device. Here are the results using the Onvis plug :

I am close to a solution ...
What other Matter devices you have? : )

That's great news.
I only have these smart plugs at the moment, if you confirm what other matter devices you are likely to support then I can look into purchasing if not too expensive.
I've purchased the Zemismart matter hub from Aliexpress which I should receive soon.
I have one Matter bulb, one LED strip, and one Aqara P2 contact sensor. Probably I will stop here, for now, these are enough to satisfy my curiosity ... : )
It will be more interesting when handling Matter Bridges functionality is added to HE (this is where the Zemismart/Tuya Zigbee to Matter Bridges will come into play).

I have published an update - ver. 1.0.3 2023-12-28 - (dev. branch) added initializeCtr and duplicatedCtr in stats; added reSubscribe() method.
I couldn't make the automatic unsubscribe->subscribe sequence to work reliably with the different Matter devices that I have.. : ( So as a temporary solution - there is now a new button "Re-subscribe".
Clicking on it will first unsubscribe the driver from all the previous subscriptions (probably multiple subscriptions), that result in duplicated events received on every on/off operation.
Do not click on the Initialize button - it will result in creating multiple subscriptions and duplicated events, as it is currently in all stock drivers with all Matter devices that I have tested.

Thanks @kkossev for the work on this driver!
I am using Kasa KP125M Outlets I have one on your driver now, it was sending 4 messages per event. I used the resubscribe and back to single events now.
Cheers!

I have just added a meross matter plug https://amzn.eu/d/2LKqaTw and everything appears to be working except no power monitoring which the plug apparently supports. Is this feature not supported in Hubitat?

Matter standard does not currently support power monitoring. Hopefully, this will be implemented in a future version.

@kkossev,
Just wondering why one of the matter Meross plugs has an high number of Hub actions?
The dehumifier plug seems to be okay.
The Meross plug may be sending periodically its on/off status as a heartbeat, or similar ...
Enable the debug logs to see.

Do you see in the Events window which app is sending periodically the on() command?
In my opinion, when a driver command on() is called - it should be executed unconditionally, no matter what switch state the driver 'thinks' it is ... last state may be wrong. So the driver should not filter commands.
