Yeah, I played around with HTTP Posts messages as well and had the same experience. Only able to power on/off. I unfortunately still had no luck getting the home assistant to connect to the Lighthouse with bluetooth. Somehow, and I’m not sure what I did, I managed to get the moonside to connect to Wifi and stay connected. Again, I have no idea what I did differently, given the buggy-ness of the app, it is likely a fluke. It’s been working on wifi for about a week now. In HA, I just use the google sdk integration with the command “Toggle moonside light” which has a delay, but works. I can also send commands to change it’s color and brightness, but I’m not able to switch themes or get its state.
A youtuber made a great video about making your own bluetooth integration
The problem is this came out before HA updated it’s bluetooth, so the instructions here don’t work. He promised to make an updated video and once he or anyone else makes a tutorial I’ll try again.
