{"NAME":"LSC Mood Light","GPIO":[0,0,0,0,37,40,0,0,38,41,39,0,0],"FLAG":0,"BASE":18}

This device uses CB3S module which needs to be replaced with ESP-12, ESP-C3-12F or ESP-12H module. Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill.

The button is on GPIO16, but as this pin does not have an internal pullup you need to pull it up externally e.g. with a 10k resistor from VCC. After that you can assign “Button_n” to GPIO16 in the Tasmota template.
