Theengs Gateway does not find anymore Xiaomi Mijia sensors.
Hi,
at some undetermined time, after some system updates, the daemon has stopped detecting 2 Xiaomi Mijia sensors, which were working fine before.
The gateway is installed on a Proxomox VM, Debian 11, standard python 3, with a passthrough on the USB port, and "hcitool lescan" seems to work:

And there it get stuck.
How can I proceed?
You are reading the sensors every 5s. Probably the battery died. I had the same issue. I tried to set to passive mode. But my raspberry os does not allow this. For the moment I set the time to every 10min. But for the long term I will probably switch to another solution which reads the sensors passive.

That's not it!
Not only I have an alarm set when batteries go under 10%, but the two sensors work fine with another little python demon (which I think uses passive mode, but maybe different libraries): https://github.com/JsBergbau/MiTemperature2
The exact same thing is happening at home, on a RPi 3, which has a debian 11 derivative distribution, so maybe there is something wrong with the debian shipped default libraries...
