I have been testing a number of these cheap Zigbee based devices, and sharing my results here: On a quest to find the “perfect” mmWave device.
These look like new models though, which I have not seen yet. I have tried some other models from Wenzhi though which look very similar (but not exactly) like the ones you have shown.
A lot of these are so similar, I probably should do as someone suggested and include some pictures with my reviews, as that seems the only way really to tell some of these apart.
You can read my linked post for lots more information (and perhaps ongoing testing) but so far I found almost all of these Tuya Zigbee devices very underwhelming. Many of them spam the Zigbee network, etc.
