Finally I sent my device back to the seller, I hope to have my money back because many other devices I got of other brands do not have any issues at all. I don't understand how shelly is so expensive.

...and, by the way: 8 months old Shellies are still in warranty period. Would propose to claim for a replacement!
Yeap, I think I will.

Other nonsense behaviour, I have just checked again without the clamp and both channels had is_valid:true ... 10 seconds later shelly is no longer connected to the wifi.
After a factory reset, it last 1 minuted connected to the wifi, then it disconnects.
I am starting thinking Shelly is a crap brand, I am reading a lot of users with similar issues.
-
I don't think so, P2 pins were never used and they also have "is_valid": false . And of course, I recently tried with the clamp there and did not work.
-
With the Shelly disconnected from power supply and clamps unplugged... 10 ohms between p1/p1+ and p2/p2+ so resistances are still working.
-
With the clamps disconnected, the volts between P1/P1+ and P2/P2+ is 0V , so it looks like there is no power in the clamp pins.
Anyway to get the shelly alive again?
Is this also normal?
"hwinfo": { "hw_revision": "dev-prototype", "batch_id": 0 }
dev-prototype ??? I saw other shelly em's showing the manufacture date.

I have a similar issue, what do you have if you go to http://<your_shelly_ip>/status ?

Hi, sure, here are the settings:

My 8 months old Shelly EM is not returning any Kwh or V and the json returned by the "status" endpoint looks like this:
Code

Really sad that it did not last a year.
Thanks for your comments!
