Philips Hue show switching from unavailable to available why?


I show every min or so my hue light bulbs switching to unavailable and back to available in the logs. Why?

I use the original hue hub. I have a docker install of HA


It’s a common problem. I found improvement by moving the Hub higher and away from electrical interference. The best I managed was one or two bulbs going unavailable a few times a day. If you sit in the Hue app on your phone, you should see them going unavailable there too, so the problem is not localised to HA.

Since last week for unknown reasons I’ve had no unavailability. The problem seems to have magically gone away despite not doing anything. I’m not sure if there was an update applied automatically somewhere, but I’m not complaining.
