Cannot restart ZHA integration

dave_t_uk · November 24, 2025, 3:38pm

I’m pretty sure I used to be able to restart the ZHA integration.

In the above dropdown or something very similar to it, there used to be a ‘restart’ option in 2025.10.x and earlier.

But now that option has gone away. So when my ZHA network completely fails and needs restarting (still happens to me about once every 2 days), I can’t find a way to do it.

It stays at ‘initialising’ and I don’t know of a way to get past this without restarting HA completely.

Other integrations have a ‘reload’ option.

Am I missing something?

I have Reload in mine.

it’s still there indeed.
Your issue with zha initialsing sounds more like a USB instability (power) issue, which is probably rooting from PI

As you can see from my screenshot, it definitely isn’t there on my setup. Weird that it’s there on other peoples’.

The actual problem is probably this one:

ZHA - application controller is not running

integration: zha

### The problem My ZHA entities couldn’t be controlled anymore although all Z…HA entities seemed available and fine. No sensor updates and errors logged when sending commands (example logging included was a turn on service) . Even reloading ZHA suggested that ZHA was fine, but the failure state remained. Shortly Un-plugging the ZBDongle-E (Sonoff stock Firmware: 6.10.3.0 build 297), resolved the issue. So for some reason the ZHA watchdog didn’t notice this hanging dongle state for hours! ### What version of Home Assistant Core has the issue?

So all mains devices should have been made unavailable by ZHA (my timeout for mains devices is 5 minutes)
