Bluetooth device (Washing Machine) constantly becomes "unavailable"

Hardware
1

Hi. I have a Beko washing machine, that has bluetooth.

Originally, it conneects to the HomeWhiz app, but I was able to get it to connect to HA using HomeWhiz Inegration and a bluetooth dongle.

The problem is that, sometimes, I go to use the machine and i notice that it is “unavailable” in home assistant.
The fix is to restart the HA container, and it usually comes back.

Checking the logbook, i see that the machine constanlty becomes unavailable, usually when it’s turned “off”.

I would assume the issue is not on the machine side, since restarting the HA container brings it back up, which makes me think the issue might be in HA or on my dongle. (Don’t think restarting the container reboots the dongle either…)

Any ideas of how to solve this?

For context, this is how i’m passing my bluetooth dongle to HA

How far between the HA install with the BT adapter is it from the washing machine that you need to connect to?

I would look at getting a bluetooth relay setup closer to it to improve signal strength and if that still does not solve it then the issue may be the way that the integration works especially if its cloud reliant for control of supported devices as it may be an issue on their end when this happens with the API.
