We had a power failure, was only down for a short time. 5 of my 6 shelly 2.5 disappeared off the network completely. I tried to reset from the button on the case, which I have done before. They never do the 3 clicks they do when the reset.
Nothing else in the house had any trouble. Anyway to try and save them? or should I assume they are bricked? I should add that several of them are left in off state, can't even use the lights associated with them, and one seems to be left in on. Nothing happens when I push the light switch to change the shelly state
