Philips Hue bulb keeps going unavailable

Recently one of my Philips Hue bulbs keeps appearing as unavailable in home assistant for a few seconds before it becomes available again.

I’ve tried reinstalling the integration but it hasn’t changed. Its beginning to interfere with my automations.

Has anyone had any similar issues and if so have you been able to fix it?

It is likely the bulb and not the integration that is the cause.
Make a successive test by switching some bulbs around.

If the error follows the bulb, then the bulb is having issues and might need replacement.

If the error does not follow the bulb, then you have issues with the signal in that area. Something might be blocking the signal or jamming it or the location is to far from the rest of the Hue/Zigbee network.

Are you using the hue bridge or zigbee usb stick?

I am using the Hue hub

I think it was the ZigBee network. I changed the channel and now it all appears to be stable.

I will keep monitoring and see how it goes.

I just received a new update for my hue hub and now my bulb goes unavailable too.
They come back after some seconds though.
It installed the update manually and experienced the drop out right away, where the network were rock stable before.
I have a Lovelace card with just hue availablity status listed from the hue devices, so it is easy for me too see the difference.
