Hi,
I have a couple of Chihiros lights as well. I had purchased the Wifi bridge also. When it work, it was fine, but was not very durable. I went thru 2 of them in about 9 months. They just died and I couldn’t reset them,
Like you I started searching and I found this https://github.com/TheMicDiet/chihiros-led-control. and it works great. You can control the lights thru HA easily.
I used as ESP32 with ESPhome to create a bluetooth proxy and it has worked flawlessly. https://esphome.io/projects/?type=bluetooth.
I’m working on using Ashely’s Light Fader to do ramp up/ramp downs. I think it should work out great.
Check it out!
