Thanks! I started using @pkozul’s floorplan years ago for our home. I never got as fancy as some but literally use it daily. Floorplan for Home Assistant
Glad you are having luck with the 12v lighting. I had made some ESP32 controls with dimming that I could retrofit but ran into a major issue when I could only find a 12+ wire running to the lights: RV 12V Lighting Control - with Dimmer Switch control - #12 by yousaf465
Hope you share any success you have. I did try using a common ground but did not work for me either.
And GOOD LUCK with the BT sniffing. I tried on a Renogy unit a year or so ago and learned that I was not meant to do that stuff lol (aka unsuccessful).
