HA Config

In global config:

homeassistant:
  packages: !include_dir_named packages

# https://www.home-assistant.io/integrations/mqtt_statestream
mqtt_statestream:
  base_topic: homeassistant
  publish_attributes: true
  publish_timestamps: true

Then put openevse_*.yaml files in config/packages folder

view.yaml is the Lovelace dashboard section above

openevse_integration.yaml is the one you'll need to customize.

EVSE Config

Shelly

I am using 2 Shelly EM:

• One connected to the wire going to the EVSE box, to measure the whole EVSE consumption
• One for the grid

Yes indeed it works quite nice at the moment, I was using MQTT myself directly but an integration is just easier as it provides all the buttons, switches etc already set.

What I am trying to do at the moment is to implement an alternative to the self-production auto adjustment that is in OpenEvse.
I find it so unreliable and it would make more sense to keep it in HA and leave the wallbox to do only on/off.
I saw yours and I also saw someone else doing that but via OCPP instead of MQTT.

@mathieucarbou would you mind sharing the configuration for the binary_sensor.grid_tarif_hc and the related scripts script.openevse_charge_manual, and script.openevse_charge_auto? My utility provider doesn't charge the high time of use rates on national holidays so I'm looking to use HA to enable auto charging on those days. But I have limited experience with HA and its automations.

But otherwise this is great work, Thanks.

  - alias: "OpenEVSE: Charge HC"
    trigger:
      - platform: state
        entity_id:
          - binary_sensor.grid_tarif_hc
    condition: []
    action:
      - if:
          - condition: state
            entity_id: binary_sensor.grid_tarif_hc
            state: "on"
        then:
          - service: script.openevse_charge_manual
            data: {}
        else:
          - service: script.openevse_charge_auto
            data: {}

@e2thenegpii : everything is there already, but I have just updated the files to their latest version.

I see them now, I just needed to look a little harder, thanks.
