Greetings from Austria!
I’m using 2 emontx with 3phase firmware, 1 emonpi and a local emoncms installation on docker + ubuntu (I got it working)
my goal is to monitor the consumption of the house (overall) and to find during the day when do I have which consumption to evaluate a PV
On the emoncms I can see the live input values of the emontx which has his sensors (P1,P2,P3,N) at the main lines. on the input side at the emonpi I have for lines P1-P3 the processes:
P1: >0, Log to Feed P1
P2: >0, Log to feed P2
P3: >0, Log to feed P3
Power1: Log to Feed P1
+ Input P3
Log to feed new feed: Use
Power to kWh new feed: Use_kwH
At first I saw on the emonpi in the feed Use and kWh values but then it was like only once …nothing was added.
Then I tried the same on the emoncms level - but there it never worked (I initialized the input with HomeEnergy Monitor of the emonpi, and when it didn’t work then with the same of emontx - both have the value Null in the feeds. The only hardware change I did was to plug the emonpi with the usb on an USV and the 9volt plug is on the normal ac. I tried now several times erasing the inputs and try new but with the same result - live input works but adding calculation doesn’t - what mistake do I make? Thank you very much for your help!!! BR Gerald. … To add something: I used one emontx plus the emonpi with emoncms on docker in a Synology for 2-3 years now. Now I deleted everything, made an upgrade of all components to the latest version (3phase emontx and emonpi with sd card). I deleted now all inputs and data and try to make it new - still the same result - it seems as the +input doesn’t work… BR Gerald.
