Frequency Output

Was wondering if there are any plans to export the frequency, Hz, to emoncms or others? Would like to be able to log that though normally it is a nice steady 60 Hz, but when I am on emergency generator I would like to capture what it is.

You can do that now. Just add the voltage channel as an output in the Emoncms configuration and set the units to Hz.

If you want to look at your historical frequency, just define an output for the voltage channel with units Hz, then run graph. The output will appear in the outputs group on the left.
