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

Hi Mathieu, i think the view.yaml that you publish is not the last one, the first screen, or am i wrong? (the last is the first screen?)

Hi Mathieu, i think the view.yaml that you publish is not the last one, the first screem, or am i wrong? (the last is the first screen?)

The code is updated but the screenshots not: the only change if I remember is the addition of the switch count. I don't update the screenshots for such minimal change.

Hi, I have only seen now your work, very interesting.
I wanted to ask you if there is a specific reason why you use MQTT directly and not the integration already available for OpenEVSE
https://github.com/firstof9/openevse

I am interested in the automation you have built on top of it

@doppiaemme I know this project. But at that time, it was very limited because MQTT / ws / http api in OpenEVSE was very limited. I also don't like to rely on http com (prefer mqtt) and if I remember the project was relying on the http api before (not ws).

I contributed to OpenEVSE codebase to add a correct MQTT support for sensors but also config (I refactored their config system). This was a first basic requirement to get a nice HA integration (OpenEVSE devs are sadly not knowledgeable about HA).
Then I proposed these packages files.

I didn't want to participate in the HA plugin dev because I prefer the flexibility of yaml code and package. The plugin might be nice for someone who is satisfied with limited features, but at the time it was too limited. I hope that since my changes in OpenEVSE codebase, the plugin has improved. But with such plugin, you are limited to what the dev exposes.

And I didn't want also to contribute a HA discovery implementation directly in OpenEVSE for the sane reasons: an HA discovery impl would probably limit to the bare minimum and would not allow more flexibility.

So I find this alternate approach with packages more flexible and easier to adapt to our need by commenting out sections and sensors, and also include some scrips and automations.

There are many ways to make it better also by grouping these templates per device, like an HA discovery impl would do, but I didn't do it.

I think that the nature of OpenEVSE bing already quite a geek-style EVSE car charger, any geek using HA should be clever enough to understand this gist and adapt ;-)

[edit]

I've looked at the commit history in the plugin and I am pleased to see it has been updated a lot to reflect the current OpenEVSE state :-)

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.
