Home-Assistant MQTT configs

EDIT: I made some changes and improvements to the configurations below but decided to move them to github to make it easier to work on going forward.

https://github.com/mdallaire/ovms-hass-configs

Here is an extract of my Home-Assistant config for various sensors and a pre-heat switch for my Leaf 2015 on OVMS. Hopefully it will be helpful to get people started with Home-Assistant and OVMS.

This will give you multiple sensors, a location device and a switch to turn on/off the pre-heat.

There is space for improvement, especialy with the drivetime/parktime where I would like to convert the second timestamp to a real time sensor in HA. So feedback is more than welcome :)

### This goes under your mqtt platform configuration

sensors:

      topic: "ovms/[mqtt-client-name]/[vehiculeID]/metric/s/v3/connected"
      payload_available: "yes"
      payload_not_available: "no"

For the pre-heating, since the mqtt topic where its turned on and off is different from where the status is I created a small automation to turn the switch off based on the real status of the HVAC

- id: '12346' #Generated by automation interface
alias: Leaf - Status Heating
description: ''
trigger:
- platform: mqtt
topic: ovms/[mqtt-client-name]/[vehiculeID]//metric/v/e/heating
payload: 'no'
condition: []
action:
- service: switch.turn_off
data: {}
target:
entity_id: switch.leaf_heating
mode: single

I also created an automation that combines the lat and long into a device_tracker for the car.

1. In the device_tracker.yaml file add the following:
   

   leaf_2015:
   name: leaf_2015
   mac:
   icon:
   picture:
   track: true

2. Create an automation with the following:
   

   - '12346' #Generated by automation interface
   alias: leaf location
   description: ''
   trigger:
   - platform: state
   entity_id: sensor.ovms_leaf_longitude
   - platform: state
   entity_id: sensor.ovms_leaf_latitude
   condition: []
   action:
   - service: device_tracker.see
   data_template:
   dev_id: leaf_2015
   gps:
   - '{{ states(''sensor.ovms_leaf_latitude'') }}'
   - '{{ states(''sensor.ovms_leaf_longitude'') }}'
   mode: restart
