WARNING: New Tuya devices have replaced their Wi-Fi module with one incompatible with Tasmota!!!
Tuya-Convert might not be possible for this device since the template was added (2020-09-22).
Will require the standard Tasmota shutter support and calibration.
Added some rules to get the switch working, based on https://tasmota.github.io/docs/Blinds-and-Shutters and copied from another curtain switch page below.
