support phase currents, and three-phase with enphase envoy

[pdeliot]

To use enphase template for circuit, phase current is required.

This information information is available for single and tree-phase.

Three-phase support is also required (for me ;-) )...

Attached sample file with Tree-phase.

envoy.json
Below a little sample extract of available data:
{ "consumption": [ { "type": "eim", "activeCount": 1, "measurementType": "net-consumption", "readingTime": 1729414585, "wNow": 5364.339, "whLifetime": 48631628.574, "lines": [ { "wNow": 452.054, "whLifetime": 20136453.749, "varhLeadLifetime": 5727861.458, }, { "wNow": -98.144, "whLifetime": 1634255.145, "varhLeadLifetime": 4811478.811, }, { "wNow": 5010.429, "whLifetime": 26860919.68, "varhLeadLifetime": 1345115.396, } ] } ] }

I can try to work on it if you can point me a sample template for tree-phase and/or phases currents...

here you can see an example, how to add currents to a template https://github.com/evcc-io/evcc/blob/master/templates/definition/meter/shelly-3em.yaml

it should be the same syntax as for power

evcc/templates/definition/meter/enphase.yaml

Line 23 in 27e45a2

power:

the jq should be
jq: .consumption[] | select(.measurementType == "net-consumption").lines[0].rmsCurrent

where
lines[0] = phase 1
lines[1] = phase 2
lines[2] = phase 3

Thanks,

I've started a first implementation that looks to work.

powers: - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[0].rmsCurrent - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[1].rmsCurrent - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[2].rmsCurrent currents: - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[0].rmsCurrent - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[1].rmsCurrent - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[2].rmsCurrent voltages: - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[0].rmsVoltage - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[1].rmsVoltage - source: http uri: http://{{ .host }}/production.json?details=1 {{- if .token }} auth: type: bearer password: {{ .token }} insecure: true {{- end }} jq: .consumption[] | select(.measurementType == "net-consumption").lines[2].rmsVoltage
Now I need to check this is working on single-phase systems.

Is it expected/better to have 2 version of the template? Or a parameter to define 1 or 3 phases? Or it will deal automatically with error on phase 1 and 2 ?

[VolkerK62]

But powers is wNow and not rmsCurrent.

[pdeliot]

But powers is wNow and not rmsCurrent.

Yes! Fixed.

Now I have severall questions

• Understand how to deal with single and three phase definision
• Is it possible to use ONE query for several indicators (to avoid querying once per value. All the values are in the returned json)?
• How can I push the contribution?

Understand how to deal with single and three phase definision

How does the JSON für single-phase looks like?

Is it possible to use ONE query for several indicators (to avoid querying once per value. All the values are in the returned json)?

Not sure, but I don´t think so.

How can I push the contribution?

create a PR.
Best way would be, to modify the actual template, if it is working under all circumstances
