Anyone knows if it´s possible to modify the sonoff pow r2 to use with 12v for example monitoring 12v solar power?
As it is now it can show 90-250V but what would happen if i use this on a 12V battery?
would it still show amps but not volt? or would it just not show anything?
The chip inside the original POW that performs the current monitoring is for AC current. I suspect the R2 is as well.
So i would need something like a sonoff pow for DC power then? casue it´s no way to modify it for DC i guess?
