Notes
This TuyaMCU requires a baud rate of 115200.
You only need to disassemble the "master" device - the one with five wires. The other unit doesn't have any smarts in it. When you disassemble the device, mind the thumbwheel at the bottom of the switch.
The black and red wires on the harness are ground and 3.3V respectively.
You will need to soldier wires onto GPIO0, TX, RX, and the Tuya MCU's reset pin.
Finally, the device won't function properly if the harness isn't plugged in - the ESP and the Tuya MCU refuse to talk to each other. I have not figured out why; I reconnected it, hooked it up to AC, and powered it up and insured it works.
