Ah right, I misread that chart as manufacturer not integration and didn’t really look at the details. That does seem odd that Tuya is that prevalent, they don’t seem that common on troubleshooting boards which I’d expect if they were used that much. I wonder how much self selection is happening here in the labs project and how much it will change when it’s opened to the community.

Does this Tuya include Zigbee devices? I don’t have any wifi based Tuya devices but it’s surprising how many generic cheap Zigbee sensors are Tuya.

Roughly 1/3 of my Zigbee devices are Tuya branded, if you buy from AliExpress it’s a strong possibility.
