I installed the integration; but it doesn’t do anything, it doesn’t find any players. I have two piCore / Squeezelite players in my house. Both are are currently on and playing. They don’t show up in HA. The SlimProto integration doesn’t have any way to add players. The instructions just say that players will be ‘automatically’ found and added.
Note: I did also reboot the RPi that HA is running on after installing the integration to see if that would trigger it to see the players.
