Shelly 1 pm relay stops working

My Shelly 1pm that was controlling power consume on a bulb disconnects yesterday without any apparent reason.

I have N connected and power on L, L1 and tried the 5 times on/off on the switch but I never listen relay noise and I never have power on Output.

Any way to solve this?

Yes I tried that, should I listen to relay noise any time I do the on/off on the switch? I don' t listen to any noise.

For resetting, did you cycle the supply voltage and then did the 5 times off/on of SW input (within 2st minute), after switching supply on again?

Yes, the relay should work after the 5 times pressings.

It does not work, I have power on SW any time I put switch on, but I never get power on (O) Output and I do not listen to any noise on relay.

I also can not find it anymore on my wifi network...
