3-phase Ampere devices P1 Smart Meter

[giton]

I just would like to know if the following 3 IDs (Ampere per phase) being part of P1 Smart Meter could be integrated within Domoticz as per the following post: viewtopic.php?f=14&t=34255

1-0:31.7.0(003.58*A)
1-0:51.7.0(004.85*A)
1-0:71.7.0(003.93*A)

Ideally, Ampere for each phase could be integrated as separated graphs and also within a single graph.

@giton,

Obviously the current in Belgium is presented with 2 digits after the decimal point, since some time.
However this is not compliant with the DSMR 5.0.2 specification. See: https://www.netbeheernederland.nl/_uplo ... fce1f1.pdf. On page 21 of 28 you will find:

Instantaneous current L1 in A resolution

As far as I know, the specification is still valid and not succeeded by a newer version. Also a check of my P1 Smart Meter, did not indicate otherwise.
So it is still in A resolution.

When looking here below on page 9 and 10 (https://energieverbrauchimblick.be/rail ... attachment)

--> 'Note 4' related to 1-0:31.7.0*255, 1-0:51.7.0*255 & 1-0:71.7.0*255 states this:

Note 4: In deviation to the DSMR P1, the resolution for the instantaneous currents (1‐0:x1.7.0*255 with x
=3, 5, 7) is improved from F3(0,0) to F5 (2,2)

Meaning that 2 digits are available. Honestly, I don't know who is managing this standard but I clearly have those information available with my T211 3-phase device and would have it integrated as devices in Domoticz when adding my HW:

Hi @giton,

Thanks for the information and the document.
As this is not implemented in NL, it is only valid in B.

So perhaps a PR?
