Getting started with a Raspberry Pi 2b and TXV4

Thanks Robert, I was a bit tired last night I think… Today I have 24hrs of data and can see what is going on. Yes the E values are cumulative energy in kWh for each of the power measurements.

I’m not sure why some of my E values started out with random negative values but they eventually crept into positive territory. I did a quick search, and used the following post to zero the E values and now everything is as I’d expect it to be:

Thank you for your help, much appreciated!

I’ve got one more question, but maybe this should start another topic? Forum etiquette?

Since I have a radio in my TxV4 that I am not currently using (Pi is connected by USB), could I use it to receive temperature measurements from an emonTH2 and pass them through the TxV4 to be logged by the Pi? :thinking:
