Hi @landzaat
Flashing new firmware is always a bit risky, but I succesfully flashed 2 color lights and 2 filament lights, following the instructions for Tuya Convert https://github.com/ct-Open-Source/tuya-convert.
I used a dedicated Raspberry PI 3 for it, that worked fine. After flashing the Tasmota firmware you can connect to the WiFi netwrk (the light bulb acts as WiFi AP) and do the setup. What you need is the right template string.
For the filament LEDs I used https://blakadder.github.io/templates/lsc_smart_connect_filament.html. Even though the picture is somewhat different, the template worked fine.
Anyway, the original firmware can be saved as backup, and restored using Tasmota.
I totally agree that this is the better solution. Tuya software seems to be quite protective, and there’s certainly the risk of a software update that makes the binding unuseable.
