Simple EVCC configuration frontend

[Alestrix]

EDIT: Simplified script and no restart necessary.

Hi,

I thought I'll share an extremely simple configuration frontend that I use to switch around some settings of EVCC that are not accessible through the regular EVCC GUI. The whole work is done by OliveTin and I've only put in a dumb script.

One specialty I have in my setup is that there's a contactor for 1p/3p in my electric install that I can switch via a Shelly relay. So as a side effect every time I do a config change via OliveTin, the script checks the contactor state and sets the phases: parameter in evcc.yaml accordingly.

So here's the OliveTin configuration:

# There is a built-in micro proxy that will host the webui and REST API all on
# one port (this is called the "Single HTTP Frontend") and means you just need
# one open port in the container/firewalls/etc.
#
# Listen on all addresses available, port 1337
listenAddressSingleHTTPFrontend: 0.0.0.0:1337

# Choose from INFO (default), WARN and DEBUG
logLevel: "INFO"

# Actions (buttons) to show up on the WebUI:
actions:
- title: EVCC Konfigurieren
  icon: "🚘"
  arguments:
    - name: mincurrent
      title: Minimalstrom
      choices:
        - title: 6A
          value: 6
        - title: 7A
          value: 7
        - title: 8A
          value: 8
        - title: 9A
          value: 9
        - title: 10A
          value: 10
        - title: 11A
          value: 11
    - name: maxcurrent
      title: Maximalstrom
      choices:
        - title: 16A
          value: 16
        - title: 21A
          value: 21
        - title: 32A
          value: 32
  timeout: 10
  shell: |-
    NUMPHA=$([ "$(curl --silent http://shelly-wallbox/status | jq -r .relays[0].ison)" = true ] && echo 3 || echo 1)
    echo -n "Pases: "; curl -XPOST "http://localhost:7070/api/loadpoints/0/phases/${NUMPHA}" | jq .result
    echo -n "Mincurrent: "; curl -XPOST "http://localhost:7070/api/loadpoints/0/mincurrent/{{mincurrent}}" | jq .result
    echo -n "Maxcurrent: "; curl -XPOST "http://localhost:7070/api/loadpoints/0/maxcurrent/{{maxcurrent}}" | jq .result

This is what it looks like in the browser:

Cheers
