I bought this UseeLink water/gas valve which according to the casing was supposed to be SM-AW713Z with the Zigbee radio but is actually SM-AW713 with a Tuya TYWE3S WiFi radio. No wonder it wasn’t being discovered by my Zigbee2mqtt radio!
Incorrect case stating SM-AW713Z. 
Incorrect package stating SM-AZ713. 
SM-AW713 V4.0 with TYWE3S wifi radio. 
Valve motor with two micro switches at both states (open/close) and TYWE3S radio. 
SM-AW713 valve motor and electronics. 
Tuya SM-AW713 with TYWE3S radio and controller board.
Flashing Tasmota Firmware
After soldering the wires for the UART connection to the module according to the pinout of the TYWE3S module, I was able to flash the Tasmota firmware onto it according to these instructions.
I used the Jinvoo SM-AW713 Valve device template to configure the device with Tasmota version 9.4:
{"NAME":"Jinvoo Valve v2","GPIO":[0,0,0,0,52,53,0,0,21,17,0,0,0],"FLAG":0,"BASE":1}It now operates exactly like the original but doesn’t require the Tuya cloud connection or app.
