There, FTFY! My turn to beat you this time.
And you’d need to spend a small fortune on test gear to calibrate to the accuracy that the basic emonTx is capable of. In the past, users who have carefully adjusted the calibration so as to match their supplier’s meter (which by definition is 100% accurate, even when it isn’t!) report agreement afterwards to within 1%. The weakest link, following tests on the latest batch of CT, is the phase shift variation in the a.c adapter due to voltage changes, and that’s likely to be significant only with low power factor loads.

A simple example of OOK is a radio door bell. Press the button, the transmitter turns on. Take your finger off, the transmitter turns off.
