Tuya-Convert might not be possible for this device since the template was added (2019-08-04). 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.

I haven’t been able to track down the other functions, if there are any, and haven’t cracked open the case to do any exploration.
