I just bought several Tapo devcies (motion, water and temp senors) including two different hubs. All the sensors paired properly except for one T100 motion sensor which will not pair with either hub (the second hub is in my garage as it is 150' from the house). I tried using borth Android and Apple phone apps as I have found sometimes one will work where the other will not. All devices are in close proximity for pairing and the hubs are on a wifi network with other Tapo sensors connected successfully.

It's just this one T100 that refuses to connect. I have tried multiple times and reset for each attempt. I have also tried a new battery, and I have tried on both hubs with both phones. I just get "Connection failed" every time. If it helps, the animated connection display never shows the white line with arrows indicating a connection that it did with all the other sensors (IIRC)

I assume I have a dud T100, so should just return it? I ordered from Amazon, so returns aer easy enough. Thanks
