Hi!
I'm currently monitoring a 3-Phase installation with 3CT's (only watts). And I want to compare total power consumption (KW/h) with the utility meter readings.
AFAIK I have to sum emoncms all 3-Phase KW/h readings in order to compare with the meter, correct?
Perhaps I need a "+ feed" instead of "+ input" but this process doesn't exists on the input configurator. Later, with the KW/h sumed, I can do a "+" process with the current meter reading to keep in sync with the meter.
Any suggestion?
Thanks so much in advance
Regards
Re: Comparing Emoncms power consumption with meter readings
The way I do it is to sum the 3 power inputs using +input and then log the total to a feed for kWh

Ooops, so easy to do, you're correct. Thanks!
By the way, now I have all 3 inputs summed, next I log to a Feed "Total W" and then a "Power to KWh" feed.
Now I have to find a way to sum this feed with the number of the electric company meter and display it in eMoncms. I know the measurements will not be exact, but I want to keep eMoncms and meter synced together.
I've tried add a process that sums 1105 (meter value) to my "Power to KWh" feed but I'm getting "Total W" feed + 1105.
Maybe isn't possible?
Regards!
