I have H200 hub with several Tapo T315 sensor and everything works seemly. Other Tapo devices are connected directly to WiFi.
I bought motion sensor T100 and connected it according to the instructions. I see it in the All devices list, but I can only view the HW and FW info, everything else is grayed out. At the same time, the sensor does not detect any movement. In the hub tab, I see the device as connected (together with the thermometers), but when I add a device in the "My Home" tab for moving between rooms, I see all devices in the My Home group (1x camera, 3x thermometer, 3x smart socket) and I can choose them, but the T100 is in the "Supported firmware coming soon" group and it cannot be selected. 
According to the documentation, the H200 hub and T100 sensor should be supported solutions. Both devices have the current FW version according to the application. H200 version HW: v1.0; FW: 1.3.6. build 20240829 rel.71119.
Hub was purchased in Germany few monts ago, T100 in Czech republic this week. Both countries are in EU region.
