I have 5 CC-RT-BLE-EQ thermostats, which have worked fine for many months now, thanks to your efforts. After updating to Home Assistant OS 10 two weeks ago, I have a lot of intermittent connection issues. I am using the built-in Bluetooth adapter from the Raspberry Pi 3B. The following error message comes up in the logs:

This error originated from a custom integration.

I have already fully rebooted and power-disconnected the Pi a few times, to no avail. According to the changelog, they updated the BlueZ package in Home Assistant OS 10:

Updated software packages [...] The latest version of the Bluetooth package BlueZ 5.66 comes with various bug fixes for improved communication with Bluetooth devices. [...]

There seem to be some issues with Bluetooth in home assistant 10. I thought it was because the drivers for my Broadcom dongle are missing. Which Bluetooth dongle do you have?

I am using the built-in Bluetooth adapter from the Raspberry Pi 3B.

According to the Raspberry Pi 3B specs page its this one:

BCM43438 wireless LAN and Bluetooth Low Energy (BLE) on board

Broadcom. May be also affected by this. If you ssh into the server and run this:

dmesg | grep -i bluetooth

You can check.

If you see a line like [ 355.837213] Bluetooth: hci1: BCM: firmware Patch file not found, tried:, it means the dongle is missing drivers

I'm having the same issue right now with my Raspberry Pi 3b+. Two EQ3BT thermostats were running fine. But then I updated HAOS to 11.2 (I don't know which version I was running before that) and for some reason HAOS would not boot. So I did a rollback on HAOS to 11.1. It would then boot, which was a relief. But now my thermostats are unavailable, even though my BT device_trackers work fine. Rolling back HAOS to 11.0 did not help. Rolling back to HAOS 10.5 did not work. I also tried to remove the BT adapter integration and the EQ3BT integrations, no success. Reinstalling EQ3BT in HACS did not solve it.

Anybody know how to deal with this situation?

Try a hard reboot (power cycle the machine) or run this script https://gist.github.com/dbuezas/74c18293c22e6e31bfeb332fa826527f

I put this in an automation via https://www.home-assistant.io/integrations/shell_command/ It runs if a thermostat is unavailable for 10 minutes
