Aeotech Nano Switch fail

Hi guys.

I have installed an Aeotech Nano Switch at home connected to my vera plus controller, and it was working great. However after a blackout the other night, it will now only stay on for roughly 17 seconds.

I have factory reset, and readded to the controller but its still tripping.

I feel like the surge post blackout killed it but maybe im missing something?

And help on this would be greatly appreciated.

Maybe worth speaking to Aeotec to be honest

Thank Chris.

Bought another and its working seamlessly. After extensive testing it was punted to the bin.
