Tuya-Convert might not be possible for this device since the template was added (2020-09-26). All new Tuya devices have firmware preventing flash but it is still possible to Tuya-Convert old stock devices without connecting them to the Tuya app.

Seems to be a rebranded Jinvoo of the same model number.

Relays etc numbered from top to bottom

All LED’s are white in colour however the bottom LED also has a blue LED for WiFi status (GPIO0). ‘Inverted’ has this blue LED on all the time and blinks when sending messages. Not ‘Inverted’ has the Blue LED off and blinks when messages sent.
