Bluetooth keeps disconnecting since April 2026 update

Configuration

Hi folks,

HA is running on RPi 4 (past 6 years), no issue with Bluetooth until latest update. I only have a few devices using Bluetooth - two of the fairly recent Switchbot presence sensors, and a few plant sensors. There are also 2 Bluetooth proxies running on ESPHome atoms.

If I reload the integration Bluetooth comes back on for a random amount of time, a few minutes if not longer.

The only thing in the logs (core) is of the plant sensors Xiaomi going offline. I have checked all logs under system and there is nothing apart from the plant sensors being mentioned, nothing about the Bluetooth integration.

Device: Raspberry Pi Trading Ltd bcm43438-bt (E4:5F:01:0E:A0:9B)

Any help appreciated.

Thanks folks.

Sometimes the Bluetooth radio can end up stuck in passive scanning mode, although I usually get a notice about that when it happens. Anyway, you might try powering down the Pi, unplugging it for 10 seconds, and then powering it back on. When I get the notification about the issue, those are the instructions, and that tends to fix it for me.

Hi, thanks for the reply. I did get a couple of notifications just after the update that Bluetooth had stopped and I needed to turn the pi off.

The RPi has been completely turned off a few times but it still keeps happening. I’ve also uninstalled Bluetooth more then once as well.

Not sure what to do now, unless I just role back the installation

I noticed this too, but I thought it was just my complicated 2.4ghz Apt / Flat environment. Lots of neighbors with lots of devices in a small area.

In my troubleshooting I noticed my BT RSSI values weren’t as good as I thought they should be, so I lowered my AP’s 2.4ghz power from 100% → 50% and the RSSI values improved, and the disconnects are reasonable.

I don’t know how to check what BT channel HA is using, but I assume for whatever reason in my case it is or was close to my 2.4ghz wifi channel.

Had a look at doing that but it cant be done on eero (Amazon) routers. Still having the issue though, think I’ll just have to rollback.

FYI after an ESPHome update on Bluetooth repeaters (Atoms) the issue has resolved, so obviously some conflict in the ether!

Hey sorry what exactly was the issue you were having bc I’ve been having the same issue…. Only use a few blue tooth proxies I have for switch bot blinds and roller shades and they haven’t been working for crap. Everything is up to date as far as I know, tho they show an update is there thru esphome to 2026.4.5 and I try doing it via a connection on my computer for it to do nothing. They show they are on 2026.4.4. Any suggestions would be appreciated. Thanks

Hi, the only thing I can now suggest is to unplug all proxies for say 10 seconds, and reboot HA plus your router. Have you checked your HA logs, to see if it says anything about the Bluetooth failing?

Well still having issues with my Bluetooth just stopping. I have 2 proxies and 2 Everything presence lites. I have unplugged all several times and have restarted HA as well. I guess I’ll try deleting the proxies and resetting them. I could prob do with out the proxies and just use the EPLs for Bluetooth and see if it still has issues. It’s just weird bc it was flawless up till recently

Well looking this appears to be an issue with multiple people and switch bot stuff so I guess I’m not alone in that regard.

I have very little Bluetooth devices but was similar to you in that my two Switchbot BT presence sensors were going offline. Does look like something is not at its best with the BT. What's your HA running on, an RPi? That can be very temperamental I've found,
