Squeezelite/piCorePlayer power to Tasmota/MQTT/HA

I am trying to control a smart power outlet so that a squeezeplayer state controls it.
The idea is to power the amp when the player is in use, but not otherwise.

I thought it would be easy but can't seem to find how...




I have Home Assistant and LMS integration. I can tell a player to turn on or off from HA.
But what I need is for HA to do an action when the player goes on or off, and it doesn't seem to have this option.


My power outlet runs Tasmota. Therefore, I can change its power state with MQTT or directly by http like so

http://192.168.x.x/cm?cmnd=Power%20Off

The plug is also using MQTT trough a broker, but I don't think the player will be MQTT compatible.

I thought about just running a script from the player on state change, but what's available on piCorePlayer is a script execution trigerred by gpio... Which won't do the same.

Anyone knows of a working path? Am I not seeing something that would make this work?

Any ideas of what next to try?

Thanks a lot.
