Overview

We are hoping to flash Tasmota firmware on our Treatlife DS01C Dimmer switch.

The Treatlife DS01 uses a TYWE3S Chip (ESP8266):

This dimmer has an MCU connected to the TYWE3S over the RX/TX pins.

MCU: BYD - BF7612AM28T W9He

This chip is essentially an ESP8266. The ESP-12 Chip has the same pinout.

We can desolder the TYWE3S board and flash it just like we would an ESP-12.

To flash the ESP-12, you would need to connect it up as follows:

Flash:

Disconnect GPIO-0 and toggle power to configure

Re-assemble

From the console, issue the following commands:

TuyaMCU 21,2
DimmerRange 150,1000
Rule1 on system#boot do SerialSend5 55AA00060005040400010114 endon
Rule 1 1
