After some long, painstaking work, I was able to get the Costco FEIT RGB Bulbs to work with HA… with full RGB, and even White-bulb-temperature working.
I even fixed this bug I found, where if you push the temp slider all the way to the left (bright daylight-white) it doesn’t change, but it does if you move it one tick over to the right. I simply clicked on “Options” under Tuya in Integrations, and altered all of the bulbs to limit the maximum supported temperature in kelvin to 6499.
Anyways, I’d like to know what are some recommended switches to use in conjunction with these? I do not want to do any hard wiring so they must be batter powered.
