Support for other GFI CTs? #160

Closed jasonwray closed 1 year ago

jasonwray commented 1 year ago

As far as I can tell, only the GFI CT from openevse.com is supported. I'd like to use the one already in my Juicebox. It should be technically possible to use any GCI CT via some form of offset (like the regular CT) or a calibration process. ie: Store the GFI CT value at rest, and then with the self test active.

Thoughts? Thanks!

The GFI is triggered by a hardware circuit, which only asserts a pin when a fault is detected. Therefore, there's no way to tune it via firmware to work w/ a different CT
