I bought 4 sockets in December 2023 of the type described in the post 1 above as "Tuya Smart Zigbee Plug AU 16A" - I bought it on Aliexpress. In Hubitat it is manufacturer: _TZ3000_typdpbpg model: TS011F
These are not safe to use - I even got an electric shock as a result of one the switches. 2 problems:
- The earth connection on the 4 sockets I received is not reliable. I tested all of them and found that the earth pin and earth socket were normally connected as they should be. However, if the Neutral pin is pressed slightly outwards (thumb pressure), the earth disconnects!! This is very dangerous. The pressure on the neutral can happen when the pins on the plug side are pushed into a normal socket. A person could get a bad shock if a device like a kettle is faulty and not connected to earth. I even made a video to show this.
- The socket switches the neutral power and not the active power. Dangerous because a user may think a device is switched off and that it is not live but it will be live. This is very bad.
I provided the above information to the store sixwgh but despite exchanging messages for over 11 days they never seemed to understand the problem. They sent me a video of their test, which clearly was not testing what I had described. Use at your own risk.
