This device uses WB3S module which needs to be replaced with ESP8685-WROOM-01, ESP-12, ESP-C3-12F, ESP-12H, ESPC2-12 or ESP8684-WROOM-01C . Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill. Read more about module replacement in a detailed guide.

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.
