Discussion of local control of Tuya Smart Wifi devices without flashing firmware

I have the tweaks in here to support DSP 20, 21 and 24. My strip does not have CT so that was not touched. You could use this as a drop in replacement driver or just pick pieces out if you want. It does either need to be used as a child of Johnathan's cloud driver, or if you use it standalone you have to copy some of the data values over using a third party app for it to work. I do have it fixed to send the HSV only instead of the RGB+HSV, along with a couple bug fixes I found and some other adjustments.

Need to click "RAW" on both the driver (TuyaLocalRgbLight.groovy) and library (TuyaProtocolLibrary.groovy) attached here:
