Ich habe die Box in meinen Home Assistant eingebunden, funktioniert soweit ganz gut. Hier meine Konfiguration:

config/configuration.yaml:

binary_sensor:
  - platform: mqtt
    name: "Wallbox Ladekabel verbunden"
    state_topic: "warp/SLq/evse/state"
    device_class: plug
    json_attributes_template: '{{ value_json }}'
    value_template: '{{ value_json.vehicle_state in [1, 2, 3] }}'
    payload_on: 'True'
    payload_off: 'False'

  - platform: mqtt
    name: "Wallbox Fehler"
    state_topic: "warp/SLq/evse/state"
    device_class: problem
    json_attributes_template: '{{ value_json }}'
    value_template: '{{ value_json.vehicle_state in [3] }}'
    payload_on: 'True'
    payload_off: 'False'

  - platform: mqtt
    name: "Wallbox verfügbar"
    state_topic: "warp/SLq/evse/state"
    device_class: connectivity
    json_attributes_template: '{{ value_json }}'
    value_template: '{{ value_json.uptime > 0 }}'
    expire_after: 30
    payload_on: 'True'
    payload_off: 'False'

  - platform: mqtt
    name: "Wallbox Ladevorgang"
    state_topic: "warp/SLq/evse/state"
    device_class: battery_charging
    json_attributes_template: '{{ value_json }}'
    value_template: '{{ value_json.vehicle_state in [2] }}'
    payload_on: 'True'
    payload_off: 'False'

sensor:
  - platform: mqtt
    name: "Wallbox Leistung"
    state_topic: "warp/SLq/meter/state"
    value_template: "{{ value_json.power }}"
    device_class: power
    unit_of_measurement: "W"
  - platform: mqtt
    name: "Wallbox Zählerstand"
    state_topic: "warp/SLq/meter/state"
    value_template: "{{ value_json.energy_abs }}"
    device_class: energy
    unit_of_measurement: "kWh"

switch:
  - platform: mqtt
    name: "Wallbox Maximaler Ladestrom"
    command_topic: "warp/SLq/evse/current_limit"
    payload_on: '{"current": 16000}'
    payload_off: '{"current": 6000}'
    state_topic: "warp/SLq/evse/max_charging_current"
    value_template: '{{ value_json.max_current_configured >= 16000 }}'
    state_on: "True"
    state_off: "False"
    json_attributes_template: "{{ value_json }}"

  - platform: mqtt
    name: "Wallbox Automatisches Laden"
    icon: mdi:ev-plug-type2
    command_topic: "warp/SLq/evse/auto_start_charging_update"
    payload_on: '{"auto_start_charging": true}'
    payload_off: '{"auto_start_charging": false}'
    state_topic: "warp/SLq/evse/auto_start_charging"
    value_template: '{{ value_json.auto_start_charging }}'
    state_on: "True"
    state_off: "False"

  - platform: mqtt
    name: "Wallbox Ladevorgang"
    icon: mdi:battery-charging
    command_topic: "warp/SLq/evse/charging_command"
    state_topic: "warp/SLq/evse/state"
    value_template: '{{ value_json.vehicle_state in [2] }}'
    state_on: "True"
    state_off: "False"

  - platform: template
    switches:
      wallbox_ladevorgang:
        friendly_name: "Wallbox Ladevorgang"
        icon_template: mdi:battery-charging
        value_template: '{{ is_state("binary_sensor.wallbox_ladevorgang", "on") }}'
        turn_on:
          service: mqtt.publish
          data:
            topic: warp/SLq/evse/start_charging
            payload: 'null'
        turn_off:
          service: mqtt.publish
          data:
            topic: warp/SLq/evse/stop_charging
            payload: 'null'

config/automations.yaml:

Die Automation ist leider notwendig, um das MQTT-Kommando der Wallbox richtig zu senden. Die Box hat zwei Topics zum Starten und Stoppen des Ladevorgangs, und Home Assistant unterstützt leider nur einen Topic für den Schalter. Funktioniert aber gut soweit.

Edit: Ich habe doch eine Variante ohne Automation gefunden, mit Hilfe eines Template-Switches.
