I have some switches (S-01) and some dimmers (SD-01)

According to https://devices.esphome.io/guides/tuya-convert you can load a generic ESPhome image and then use OTA thereafter.

SS-01 Switch

The ESPhome page for the device is here https://devices.esphome.io/devices/Martin-Jerry-US-SS01.

I have managed to reprogram 2 of these but can't remember how I did it right now.

It has a button and a relay and two LEDs, one red and one blue.
