Hi,
Living in the city with no garage or parking spot, I rely on public EV charging stations. While I’m waiting for my first EV to be delivered, I made a quick’ndirty integration to have the stations around me displayed in HA:
I have a station around the corner, so I can use this to get notifications when a spot gets free.
The integration uses the TomTom API that you can use for free for a limited calls per day.
Maybe this is useful for someone.
Happy Home Assistant tinkering.
Edit:
The free TomTom api only allows one call every 5 minutes, and the EV endpoint only allows to pass one station ID per call, so if you want to get data from several stations, you need to adapt the scan_interval.
The Here api allows to make a call on a zone and retrieve all EV stations within a radius. HERE Technologies Documentation | HERE Docs
My restfull sensor for a single station:
- platform: rest
name: "EV Venue Victor Rousseau"
resource: "https://ev-v2.cc.api.here.com/ev/stations.json?prox=[longitude],[latitude],[radius in meters]&apiKey=[your-api-key]"
method: GET
value_template: >-
{% set station = value_json.evStations.evStation | selectattr('id', 'equalto', 'station_id') | list | first %}
{% if station is not none %}
{% set connectors = station.connectors.connector %}
{% set statuses = connectors[0].connectorStatuses.connectorStatus %}
{{
statuses | selectattr('state', 'equalto', 'AVAILABLE') | list | length
}}
{% else %}
unknown
{% endif %}
scan_interval: 300
json_attributes:
- evStations
NB: Haven’t found an API that shares price informations so far.
