SM Command

 Silly questions but what is the syntax for using the $SM command?  I've tried $SM 240 and get $OK but when I check with $GM I get $NK.  I also tried $SM 240 0 and get the same result... any help would be appreciated.


OpenEVSE does not currently have hardware to measure voltage. The commands are there as a place holder for experimentation. 

Ah, make since! I believe the $SA command settings is where I need to be then to calibrate the current feed back then. Thank you for the update!! Oh, what does the offset do with the $SA syntax? If I use a clamp meter and find the exact current draw and apply that number to $SA setting, like $SA 225 0, what's the purpose of the "0"?
