Lights - FengtianGu/Sonoff-Tasmota GitHub Wiki

Tasmota WebUI displays Brightness and CT or White level sliders depending on your module or the number of PWM channels configured.

The WebUI doesn't have a color picker for RGB lights due to memory and flash size requirements to implement one. Instead use Color to control colors.

Refer to light commands for all possibilities to control your lights.

Channel mapping

By default the PWM channels are mapped accordingly depending on the number of used channels:

Channels	PWM1	PWM2	PWM3	PWM4	PWM5
1	Brightness
2	Cold White	Warm White
3	Red	Green	Blue
4	Red	Green	Blue	White
5	Red	Green	Blue	Cold White	Warm White

When connecting more than one light strip to PWMs, you cannot control them separately in the WebUI due to the above mapping. Use Channel<x> to dim each PWM channel individually.

Some lights use different controllers instead of PWM (f.e. SM16716 or MY92x1). In that case channel mapping is dependent on the controller. It can be remapped using SetOption37.
