Hello,
It’s probably late, but let it live for next years. I have been thinking about esp based wireless battery powered led lights for christmas tree but never found anything to buy. I know I can make it myself, but have anybody knows a similar product before I decide to make it for next years? Thx.
Your one requirement of being battery powered is the stumbling block here. My experience with esp on battery is that the battery depletes rapidly. Even with low power draw you will need more juice than you think.
Powerbanks usually have problems in case of low power draw, they turn off. I found some Chinese powerbank, which could be forced not to turn on in order to have night light in toilet room, which usually never have a 220v plug. Never turned to do it finally.
However, how much ESP32 draws to not be powered by a powerbank? I can have two and change them daily during Christmas time.
