Group switch not updating

I do also have the same problem running openHAB 2.5.9 on a raspberry 3. I think the autoupdate =“false” parameter is not the solution and I am not sure if the is a “offical” solution for the problem.

Did you try already workaroud described from @ysk already:

Not sure if this is still valid.

Running into the same issue with openHAB 2.5.10-1

Need to reload the HabPanel page to get the group switch status correctly displayed.
