Tuya-Convert might not be possible for this device if the manufacturer started using newest Tuya firmware since this template was published. Instead you can likely serial flash Tasmota without soldering with a flashing jig, if the device is easily opened.

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.
