Configure the Central System

Host address and port

  • The default host address '0.0.0.0' will listen to all interfaces on your home assistant server.
  • The default port number is 9000 but can be changed for your needs.

Secure Connection

If using Let’s Encrypt, Duck DNS or other add-ons that enables HTTPS you can get a secure WWS connection for OCPP. For more information on how to generate keys see this blog post.

  • The option secure connection enables connection thru WSS (HTTPS). With the option disabled the connection will be WS (HTTP).
  • If enabled provide pathways to SSL certificate and key files. The pathways will be ignored if secure connection is disabled.

Measurands

  • Select which measurands you would like to become available as sensor entities.
  • Most chargers only support a subset of all possible measurands. This depends most on the Feature profiles that are supported by the charger.

Add the entities to your Dashboard

  • On the OCPP integration, click on devices to navigate to your Charge Point device.

image

  • At the bottom of the Entities panel, click on 'Add to Lovelace' to add the entities to your dashboard.

image

  • An entity will have the value 'Unavailable' until the charger successfully connects.
  • An entity will have the value 'Unknown' until its value has been read from the charger.

Configure your Charger

  • Configure your charger to use the OCPP websocket of your Central System (e.g. ws://homeassistant.local:9000). This is charger specific, so consult your manual.
  • Some chargers require the protocol section 'ws://' to be removed, or require the url to end with a '/'.
  • Some chargers require the url to be specified as an IP address, i.e. '192.168.178.1:9000'
  • You may need to reboot your charger before the changes become effective.

Start Charging
