Hi,
I got professionally installed a Shelly 3 EM by an Electician in hour house and it was working great for 15 hours. Suddenly in the Moment when we switched off a light there was a big bang , the shelly exploded and the whole house was out of power.
I searched the internet and found similar issues, this seems to happen quite often.
No Problem, I returned the shelly via amazon and I will never buy this Shelly 3EM Model again.
My Problem is: I need such a device to measure power usage. Will the Shelly PRO 3EM be more resistand and stable than the 3EM ? Is it a goog advice to buy the pro model ?
See attached Foto for the damage
