Integration does not see any BT devices at all. I also have a Mi Band 6 and others, but it doesn't see any.

Bluetooth in Home Assistant is working fine. I use many BT thermometers and similar devices.

Have you configured a device entry? Where did you get the device address from?

the XiaoxiangBMS app on my iPhone shows the address bytes in reverse order, so if the iOS app says aa:bb:cc:dd:ee:ff, the address should be configured as ff:ee:dd:cc:bb:aa.

I have the same issue very regularly. ~ bluetoothctl devices does show all devices, the addon at the (almost) same time, does not. I think the whole setup is not very robust against unstable connections as it does not use https://bleak.readthedocs.io/en/latest/api/scanner.html#starting-and-stopping but only scans once and then assumes the BMS is available ... ?

The scan uses bleak, there are some issues with bleak. If the device does not appear in the scan, batmon will not be able to connect. Try to enable install_newer_bleak and bt_power_cycle

closed due to inactivity. empty scan results is usually not a issue with batmon but with the OS, permission, container etc
