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.

Requires configuring shutter support.

As of August 2020 model SC400W-EU V3 does not have an ESP chip anymore.
