enphase: energy and power empty

[othi]

Describe the bug

My Enphase Envoy API returns the following at the URL http://{{ .host }}/production.json:
{"production":[{"type":"inverters","activeCount":22,"readingTime":1734616504,"wNow":207,"whLifetime":6787031}],"storage":[{"type":"acb","activeCount":0,"readingTime":0,"wNow":0,"whNow":0,"state":"idle"}]}

The jq query as defined here

evcc/templates/definition/meter/enphase.yaml

Line 44 in e33a682

jq: if .production[] | select(.measurementType == "production").activeCount >= 1 then .production[] | select(.measurementType == "production").wNow else .production[] | select(.type == "inverters").wNow end

does not return anything.

(.production[] | select(.measurementType == "production").wNow) // (.production[] | select(.type == "inverters").wNow) does work for me but I don't have an instance that returns measurementType so I can't be sure if the jq is correct. It's probably missing the activeCount check.

The same is true for

evcc/templates/definition/meter/enphase.yaml

Line 54 in e33a682

jq: if .production[] | select(.measurementType == "production").activeCount >= 1 then .production[] | select(.measurementType == "production").whLifetime else .production[] | select(.type == "inverters").whLifetime end

replacing wNow with whLifetime

Steps to reproduce

1. Configure an Enphase meter in PV mode
2. Start evcc

I see. Assumption was that the key are universal, but it seems that they are not. We need to check if they exist before we use them. I'll try to work on this today. @othi does production.json?details=1 return different set of keys? I see you are using http, and not https, so you have an older firmware too (not using tokens for auth)?

[othi]

The enphase template uses http itself:

evcc/templates/definition/meter/enphase.yaml

Line 37 in 5902507

uri: http://{{ .host }}/production.json

but it returns a 301 to the https URL anyway.

My gateway is on firmware 8.2.4264, which seems to be fairly recent (november 2024), and I do use a token.

As for the output of production.json?details=1:

# curl -H "Authorization: Bearer eyJra..." https://192.168.xx.xx/production.json?details=1
{"production":[{"type":"inverters","activeCount":22,"readingTime":1734687932,"wNow":442,"whLifetime":6788138}],"storage":[{"type":"acb","activeCount":0,"readingTime":0,"wNow":0,"whNow":0,"state":"idle"}]}

Hey there

I believe I have an answer for this. I've tested with your production.json as well as mine and from few other folks and it gives the right answer:

jq 'if (.production | length) > 1 and (.production[] | select(.measurementType == "production").activeCount >= 1) then .production[] | select(.measurementType == "production").wNow else .production[] | select(.type == "inverters").wNow end'

jq 'if (.production | length) > 1 and (.production[] | select(.measurementType == "production").activeCount >= 1) then .production[] | select(.measurementType == "production").whLifetime else .production[] | select(.type == "inverters").whLifetime end'

If there are more than 1 member of production array, it checks if production's activeCount is, basically, not null (which means it's enabled). If all that is true, it returns the value from CT's wNow reading. If any other case it just returns inverter's wNow.

I'll prepare a patch for this...
