What does esp_reset_reason() say immediately after reboot?All good, but during final tests i started to face random hardware reset... or something which makes my board to reboot.

Any suggestion is more than welcome.

Re: random hardware reset
Good question!
The device is already in production controlling my pump in the garden, but it worth to open it to get the answer to the question.
Will do this in a couple of days, because i need to bring it back to my table.

Somehow, I expected this... but why... i surrender and give up.
Maybe you want to know how i found the solution with the wire connected to J2 pin2. Simple, i put a scope probe to J2 to see if any glitch. Obviously, no glitch and no issue. Then i removed the probe but i kept the wire used to connect the probe and... by magic: issue is gone! Remove the wire: issue is back.
See in the picture the guilty wire.
