February 12, 20224 yr I have a sonoff TH16 attached to my solar water heater that I use in conjunction with an added heating element. Would anyone know how I could get a smart lightbulb to turn red when the water temperature is at a certain temperature (example 55 degrees) and turn green when it is below 40degrees) I have some cheap smart bulbs that don't seem to be able to do this. Help much appreciated.
