Can not turn on any lamps, only off works

We’ve got exactly the same problems you are seeing all since the latest hue update. Lights show as on randomly and can’t be Controlled, a reset of Vera solves it but it does not always last more than a day before they lock up again.

Only this morning I notice many hue lights showing as on which they are not and like you we can only get control back with a brightness change or a Vera reset. Very odd as worked well across both hubs in the past. It does seem to effect only lights on one of our hue hubs even though they are both on the same FW.
