Tapo has updated the firmware of the Tapo P110M to 1.4.1 Build 251020. The power on state now is supported via Matter but I haven’t tested it so can’t tell if it will obey it or not. In fact, the option in Tapo app and the option in Matter are not in sync so who knows which one the plug uses 
They didn’t include support for On with Timed Off though.
Edit: Feb 27th 2026 (this was its own comment but I had too many comments in a row…):
The new Shelly Plug M Gen3 (Matter over WiFi) has been tested by @TapioX so I’ve added it to the list of known devices that work fine with the driver, thanks!
While it reports power, energy, current and voltage, it does not support setting the Power-on state or the On with Timed Off action.
Edit: March 11th 2026. Got myself a IKEA GRILLPLATS, so far it’s great! Every feature is supported, including power-on state and On with Timed Off. The power reporting is smart too, it’s quick to report changes when they happen but doesn’t flood the network.
