Notes

The Treatlife DS01C Dimmer is single pole dimmer. This device comes with a Tuya WB3S chip and there are now two methods to make this device compatible with ESPHome:

1. Use Cloudcutter to flash the device.
2. Swap out the chip with a compatible one.

Using Cloudcutter

Cloudcutter is a tool designed to simplify the process of flashing Tuya-based devices. It allows you to bypass the need for physically opening the device and swapping out chips. By leveraging the cloud APIs, Cloudcutter enables you to flash the firmware remotely, making it a convenient and less intrusive option. Follow the instructions on the Cloudcutter GitHub repository to use this method for flashing your DS02F device.

Swap chip

The main board has the appropriate footprint for an ESP-12F. Further instructions can be found in the Home Assistant community. When desoldering the WB3S chip, take care if you use a heat gun near the black foam light guards around the speed LEDs and main switch LED. When overheated, the foam shrinks to less than half its original size. With a little patience, it is instead possible to peel the foam and adhesive off the PCB, set them to the side, and replace them after swapping out the WB3S.

The Tuya MCU UART runs at a baud rate of 9600.
