invalid meter type: custom

[obervolt]

I'm only starting with evcc and it looks very promising!

I was able to configure my vehicle and my charger. Unfortunately, I have problems to include my inverter as a meter via http. I have configured it like this:

meters:
- name: pv
  type: custom
  power:
    source: http
    uri: http://192.168.178.48/api/dxs.json?dxsEntries=67109120
    jq: .dxsEntries.dxsId."67109120".value

On executing, I receive this error message:

./evcc meter
[main  ] FATAL 2021/05/10 00:10:15 cannot create meter 'pv': invalid meter type: custom

What am I doing wrong? Whenever I copy an example meter configuration with type custom into my configuration, I receive this same error message.

I would be very happy for any hints.

Hi simply change meter type to default, instead of using custom.

meters:
- name: pv
  type: default
  power:
    source: http
    uri: http://192.168.178.48/api/dxs.json?dxsEntries=67109120
    jq: .dxsEntries.dxsId."67109120".value

Thanks! Yes, I'm using 0.53. So this should be the problem.

Unfortunately, with type:default I have the following problem.

$ ./evcc meter -l trace
[main  ] INFO 2021/05/10 00:37:38 evcc 0.53 (85c9604)
[main  ] INFO 2021/05/10 00:37:38 using config file /opt/evcc/evcc.yaml
[main  ] FATAL 2021/05/10 00:37:38 cannot create meter 'pv': cannot create type 'default': default meter config: power required

I thought, I have defined a power config? Any suggestions?

And, yes: I'm accessing a Kostal inverter. It's a Piko 4.6 - but I think it is not modbus-capable.

You have to even rename source: to type: as it is the old syntax.

[obervolt]

Thanks for your help. Now it's working. I still have to adjust the json query - my version above is not right. But this has nothing to do with EVCC or with the EVCC documentation.

[thierolm]

Simply try this jq query:

jq .dxsEntries[] | select (.dxsId == 67109120).value

Hi simply change meter type to default, instead of using custom.

custom is correct as per docs, default is deprecated. However, we have still not released the version where this change will happen (planned for 0.54).

This works on my Piko17

- name: pv
  type: default
  power:
    type: http
    uri: http://192.168.56.254/api/dxs.json?dxsEntries=67109120
    jq: .dxsEntries[0].value
  energy:
    type: http
    uri: http://192.168.56.254/api/dxs.json?dxsEntries=251658754
    jq: .dxsEntries[0].value
    scale: 0.001

The energy: node is useless for anything else then chargemeters and can be removed here.

[obervolt]

Thanks, everyone! You've been very helpful.

@premultiply For Kostal inverters, we have currently only modbus config templates on https://github.com/andig/evcc-config. Shall I create create some Kostal Web API templates? Found some documentation on https://www.loxwiki.eu/pages/viewpage.action?pageId=28803569 .

@ppistole do you have working config examples for a grid (power) and battery (power/soc) as well, which U could share with us?

[premultiply]

Wenn man auf der verlinkten Seite zu den Kommentaren scrollt stellt man fest, dass das wohl nur bei ganz bestimmten Modellen so funktioniert. Und dazu ist das auch wieder so ein Hybrid-Mist wo man sich die benötigten Werte am Ende wieder um 5 Ecken selbst zusammenrechnen muss…

[ppistole]

Yes it is true. This is only for the Kostal "Piko15-20" products. In OpenWB you can config three different types of Kostal Products

@thierolm
I use a KSEM. You can find a config here: https://github.com/andig/evcc-config#meter-kostal-smart-energy-meter-grid-meter

In case someone is interested in more http-querys for the Kostal Piko inverters. I'm using the following codes in openhab.
Some of them are only available if a external meter is connected to the inverter:

DCLeistung 33556736   
ACLeistung 67109120  
Eigenverbrauch 83888128   
HausverbrauchNetz 83886848 
Betriebsstatus 16780032  
TagErtrag 251658754 
TagHausverbrauch 251659010  
TagEigenverbrauch 251659266 
TagEigenverbrauchsquote 251659278
TagAutarkiegrad 251659279
GesamtErtrag 251658753
GesamtHausverbrauch 251659009
GesamtEigenverbrauch 251659265
GesamtEigenverbrauchsquote 251659280 
GesamtAutarkiegrad 251659281  
GesamtBetriebszeit 251658496

Some values need to be calculated:

Hausverbrauch = HausverbrauchNetz + Eigenverbrauch
Einspeisung = ACLeistung - Hausverbrauch

HTTP-Query is possible for a single value:
http://192.168.178.48/api/dxs.json?dxsEntries=67109120

Or for a set of values:
http://192.168.178.48/api/dxs.json?dxsEntries=251658754&dxsEntries=251659010&dxsEntries=251659266&dxsEntries=251659278&dxsEntries=251659279&dxsEntries=251658753&dxsEntries=251659009&dxsEntries=251659265&dxsEntries=251659280&dxsEntries=251659281&dxsEntries=251658496&dxsEntries=33556736&dxsEntries=67109120&dxsEntries=83888128&dxsEntries=83886848&dxsEntries=16780032

Um die Leistung am Hausanschluss für evcc abzugreifen, nutze ich folgende Meter-Konfiguration:

- name: kostal_grid
  type: default
  power:
    type: calc
    add:
    - type: http
      uri: http://192.168.178.48/api/dxs.json?dxsEntries=83888128   #KostalEigenverbrauch
      jq: .dxsEntries[0].value
    - type: http
      uri: http://192.168.178.48/api/dxs.json?dxsEntries=67109120   #KostalACLeistung
      jq: .dxsEntries[0].value
      scale: -1
    - type: http
      uri: http://192.168.178.48/api/dxs.json?dxsEntries=83886848   #KostalKostalHausverbrauchNetz
      jq: .dxsEntries[0].value
