Maximum Amp (Power) from grid on L1 or L2 or L3 setting

[highendsyl]

Use YouLess meter in combination with WallBox Commander2.

Is there any way to maximize L1 of L2 or L3 Amp/Power from Grid?

My Grid-fuses are: L1: 40A L2:40A L3:40A

As house-installation is divided over L1, L2 and L3 and WallBox divides power equally over L1 + L2 + L3 this can lead to power-overflow on a specific fuse: in my case this is L3.

L3 shuts off when charging with 32A and wife uses kitchen-appliances and washer and dryer all at the same time in combination with heat pump. I cannot explain her and I don't want to limit charging setting to e.g. 20A. As this limit is only required under the above mentioned conditions.

The template youless does not support L1, L2, L3 Amps. However the youless can support them: (see: Stroom L1: 19A L2: 11A L3:10A.

Would be good to add this in Loadmanagement, so each phase can be controlled. (or Powersetting for each phase)

[mfuchs1984]

You cannot control single phases of your charger, it will always distribute power equally. So when you setup load management to 40 A and phase 3 is overloaded, evcc will reduce the charge current, the charger will reduce it on all three phases and your fuse will stay safe.

In case your meter supports phase currents but it is not in the evcc template, you can enhance the template.

Try this

- name: grid
  type: custom
  power:
    source: http
    uri: http://YOURYOULESSIP/e
    headers:
      - content-type: application/json
    jq: .[0]|.pwr
  energy:
    source: http
    uri: http://YOURYOULESSIP/e
    headers:
      - content-type: application/json
    jq: .[0]|.p1+.p2
  currents:
    - source: http
      uri: http://YOURYOULESSIP/f
      headers:
        - content-type: application/json
      jq: .[0]|.i1
    - source: http
      uri: http://YOURYOULESSIP/f
      headers:
        - content-type: application/json
      jq: .[0]|.i2
    - source: http
      uri: http://YOURYOULESSIP/f
      headers:
        - content-type: application/json
      jq: .[0]|.i3

[highendsyl]

almost there I think:

output of: http://YOURYOULESSIP/f

Logging EVCC

[mfuchs1984]

Then it is even simpler, replace jq: .[0]|.i1 with .i1

Same for i2 and i3

[mfuchs1984]

If you want, you can even add the voltages

voltages:
    - source: http
      uri: http://YOURYOULESSIP/f
      headers:
        - content-type: application/json
      jq: .v1
...

[VolkerK62]

but .... currents are not signed
you can use the phasepower to sign the current
jq: if .l1 < 0 then -i1 else i1 end

[mfuchs1984]

Good catch

[mfuchs1984]

Actually

jq: if .l1 < 0 then -.i1 else .i1 end

[highendsyl]

evcc won't start: (something with currents, without current evcc will start)

[mfuchs1984]

jq: is missing, sorry ;)

Use
jq: if .l1 < 0 then -.i1 else .i1 end

[highendsyl]

EVCC won't start. Where is my mistake?

[VolkerK62]

jq: .i3
jq: if .l3 < 0 then -.i3 else .i3 end

only one jq .use the formula
