Tuya Generic S11 Universal IR+RF Wifi Remote Control

General Notes

There's detailed teardown info at Elektroda.

This model includes RF besides IR. You can use the external component Tuya RF to integrate RF capabilities, but still note that you will need to write the RF codes into your ESPHome device (there is no remote.learn_command).

GPIO Pinout

Pin	Function
P7	IR Transmitter
P8	IR Receiver
P9	LED
P23	Button

Flashing

I used tuya-cloudcutter, allowing for disassembly-free flashing, to flash an ESPHome kickstart image. From there, you can just build your own image and upgrade to the latest version.
