You were lucky to get them paired to Vera in the first place.
I’ve been trying to pair an Xiaomi Aqara Temp / Humidity sensor to my Vera Plus and it no longer works or pairs at all.
Regarding the “Can’t Detect Device” red banner annoyance.
On the problem door contact device try setting Automatically Configure to NO and Polling to 0.
Change CommFailure variable back to 0 and see if the red banner message comes back ?
Also take a look at this thread here where some time ago we were talking about these Xiaomi Aqara devices and Vera. You can find some tips and tricks.
In fact I tried pairing that same Xiaomi Aqara Temp / Humidity sensor to an Ezlo Plus and it didn’t pair with that hub either. So maybe I have a faulty device?
Although Ezlo have not officially confirmed Xiaomi Aqara Zigbee devices will work with their Ezlo hubs to my knowledge and Zigbee devices never worked well with Vera hubs.
