Sure. Maybe someone else would implement mrm support on his own. I will consider reimplementation if I convince myself to buy Pro as I have only one device atm.Onlyoneme, thank for your work, I tried to use your integration. Works well for playback control.
But as you can see, I am interested in multiroom management and automation of these processes. Including between devices on the A31 platform and WiiM.
In the official app it works without any problems. I hope someday it will be possible in the Home Assistant.
