This device uses WB3S module which needs to be replaced with ESP-12 or ESP-07 module. Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill.

This dimmer switch is manufactured by Earda Technologies and sold under many brands such Girier, Lonsonho, Moes, Tessan, white label and more.

Serial Flash

Unit contains a WB3S tuya chip. I transplanted an ESP12F module in it’s place pre-flashed with tasmota via serial flash. If you use ESP-12F/E module, you must ground GPIO15 with a piece of wire or solder or the switch won’t power on.
