Please refrain from giving this kind of advice. It’s dangerous!
Nothing more to say - I’m out of this thread.
Well sorry if it's wrong you've told me several conflicting things and I'm doing my best to parse out reality from fiction.
Can you or anyone provide 1 single reason as to why the Shelly 1L Programming header cannot be used while connected to mains voltage? Which pin on the header is the dangerous one? DBG TX, TXD, RXD, RST, and GPIO0 are all connected directly to the ESP inside of it, correct? 3.3v is connected to the 3.3v output of the regulator that supplies voltage for the ESP. GND is connected to Sx, yes, but so is the GND on the ESP chip. Is any of this incorrect?
If all of it is correct then it's just as safe for anything you plug in as it is for the ESP chip.
ZitatNo, Sir, this is not simple to implement!
A cut of the wire trace and a jumper wire. It is literally that simple. Connect the jumper wire from the programming header GND pin to the GND of the 3.3v regulator and you are just as safe as the ESP chip.
Of course this is predicated on you giving me accurate information in this thread so if there are inaccuracies in what you've previously told me by all means I beg for enlightenment, that's why I made the first post to begin with!
