I'm curently sending the smart-main readings from Flukso to PVoutput which works fine. The Flukso is hooked up to the P1 port of my smart meter and has a sensor called smart-main energy. The smart-main sensor is however based on the calculation consumption - generation (from solar panels) which are both available as separate readings from the P1 port interface.
I'd like to read out the consumption data as a separate reading as well as I monitor my solar panels before the smart meter and I can use PVOutput to calculate all the values I'd really like to know (generation, total consumption and solar panel self consumption).
Is this already possible and if not, could I submit this as a feature request for a future firmware update.
I would like this as well. The P1 port sends more detail info, that is now hidden.
A good start would be to show negative values in the graphs in the dash. At that point energy is delivered to the net.
I should like seperate values in the dash graphs of the "slimme meter" (Kaifa M105) for the positive T+(consumption) and the negative T-(generation). A red line for the T+ and a blue line for the T-.
I agree with Moerbeek that a good start would be to make the negative values visable in the graphs.
The readings from the P1 port are consumption and generation (=0) in case there are no solar panels.
With solar panels (after the meter) this changes to import and export. Consumption is now a little bit more complicated to calculate:
consumption = import-export+solar
With import and export as separate readings, pvoutput could calculate the net consumption. Without these separate readings it is better to use flukso v2a with a clamp for measuring consumption.
Thanx for the extra info. As I'm not planning on using clamps (it feels like a step backwards) it would be great if we could read the import as a seperate value with our Flukso v2b. PVoutput could probably do the math from there.
Showing negative values on flukso.net as suggested by omoerbeek would be nice as well.
(although I'm afraid development on Flukso is pretty much dead seeying the activity on the forum and the blog .. :-( )
The smart-main value is obtained by subtracting import from export, not consumption from production. The latter is not known by the smart meter since it's only taking measurements on the main power feed. E.g. your appliances might be consuming 500W with your PV panels producing 1000W. Your smart meter will then report 500W export. But you might as well be consuming 1500W and producing 2000W, netting the same 500W export. So the Fluksometer simply subtracts the values (import - export), resulting in a signed integer ("+" for consumption, "-" for production). No information on production/consumption is however lost, since the smart meter simply does not measure net production/consumption. You could obtain those values by measuring solar production with an extra clamp or DIN-rail meter. Net consumption would then be smart-main + PV production, as indicated by Driek.
The smart-main values (i.e. net electricity export) are not yet properly charted (but are reported when hoovering your mouse over the chart). This will be fixed in the next dash iteration.
Flukso code is not written in the forum or on the blog. They are a bad proxy for development activity. A better indication of development activity is to look at the commits in the different Flukso code repositories on Github. Have a look at e.g. the flm02, the cloudi_service_flmqtt and the tmpo-py repositories. Observe how undead Flukso really is.
Good to hear Flukso is still very much alive. I understand your explanation but I'm still looking for a way to calculate my consuption, preferably on PVOutput.org since it's more flexible then the Flukso dash.
I have the PV production values (monitored before the smart meter straight from the inverter and send to PVOutput.org) and I have the smart-main value from the Flukso which is also send to PVOutput.org. So I should be able to calculate the actual consumption right. So it looks like my question is more a question if there are any options out there to automatically calculate the consumption value.
Just take the sum of smart-main and your PV production and you will get your actual consumption.
I get that but I'm looking for a way (a tool) to do this so I can visualize it, preferably on PVOutput.org. But I guess there is no such way. Thanx for the responses.
