I have a couple of the Govee H1162 Music Sync boxes in my environment and they seem to only work via Bluetooth through the app. I know there is a Bluetooth adapter in my Raspberry PI 4B and it is active and I see them.
These show up in my Govee to MQTT list and it looks like I have a power switch I could toggle on and off but it does not work.
I am guessing that the only way I could do this is if it actually connected to Bluetooth and with it not a traditional Bluetooth connection (which happens with my motorcycle for its light controller).
I might just have no solution at this time. I wish these things connected on the wireless network like every other product I have from them.
