Tuya-Convert might not be possible for this device since the template was added (). 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.
NOTICE!!! Manufacturer has started using unsupported non-ESP8266 chips recently and this device might not be compatible anymore. Check seller descriptions or contact them before buying!
There is a new version with a T102/WR2 WiFi module in it. This uses a RTL8710BN chip and can not be converted to Tasmota. Make sure that you get a plug with TYWE2S WiFi module based on ESP8266.
