Incorporate mains voltage sensor and CT?
I'm working on planing my system, and would love to be able to track the control panels voltage and current in Brucontrol. There are cheap ac voltage sensor boards that output DC analog voltage at 5 or 3.3V. And I've used current transformers (CT) in past projects where a simple circuit can give analog DC voltage out.
My question is about processing the signals. Looking at the documentation it doesn't sound like there is a way I can use a script to calculate RMS values sampling at 60HZ.
Is there a clever way to do this without going to the device firmware?
