Although the Tuya SMART WIRED GATEWAY PRO hub is compatible with matter, it is not properly recognized in smartthings. Specifically, I have issues in recognizing the Tuya presence sensor: ZG-205Z which, despite being connected to the Tuya smart wired gateway pro, it is not correctly recognized in smartthings.
I would start by getting in touch with tuya support for whatever company sold the gateway. Find out exactly how that device should appear when bridged. (For example, that kind of sensor often shows up as one motion sensor per zone rather than as an occupancy sensor.)
Also: did the gateway itself add OK? Is it showing in SmartThings as a matter bridge?
For example, here is how my aqara M2 hub shows up as a matter bridge in the SmartThings app:
The gateway is listed as a device, and it says connected.
The matter logo shows down towards the bottom right of the page.
The individual child devices are listed on the right as “connected devices“
Correct, I firstly add the presence sensor to the tuya hub and then I share the hub in smartthings. In this way the sensor is imported in smartthings. I send the images here below. It appears like your devices but my problem is that my sensor in smartthings is stucked showing presence and I cannot find any useful option that I can set.
I tried to connect this gateway to smartthings. And I failed. It works the way Andrea B described. But the big problem is : after adding it to ST it brings all the device in ST. But if you add ine device more, this devices will not shown in ST. If you delete the Gateway I cant add it again. I must reset the complete gateway. So it is useless
