A Home Assistant Script to auto-discover MQTT topics populated by the Teslamate application
- Copy the yaml file contents into your configuration.yaml, or if you use packages save the entire YAML file in your packages folder.
- Edit line 21 with your HA auto discovery prefix. If you don't know what this is, leave it alone.
- Add your vehicle on lines 27-33. If you have multiple cars, make additional list entries.
- In Home Assistant, go to developer tools > YAML and click SCRIPTS to reload them.
- In Home Assistant, go to 'automations' > 'scripts' and run 'Teslamate Entity Creator'.
- Modify, add, or remove any sensor starting on line 51. All entries under the "config:" key are documented here:
https://www.home-assistant.io/integrations/sensor.mqtt/#configuration-variables
In order to pass a template, the brackets must be commented out. Use the following example as a reference:
value_template: "{{ '{{' }} value | float(0) * 1.234 {{ '}}' }}" - Create an automation to re-run this script whenever the software version sensor is updated. This ensures the correct software version is shown on the MQTT device page for each vehicle.
