Hi,

I bought 8 shelly 2.5 for rollers shutters, for 3 of them, when i add to the network, the device is not visible anymore, i tried to search it in hidden device, but there's not there too.

How i can do to resolve it, should i re-initalise it again? what's the better way to do it?

PS:The same problem are happened with Shelly 1 (for light)

Thanks a lot for your help.
