Environment Canada
The environment_canada
weather platforms provide meteorological data for Canadian locations from Environment Canada.
The following device types and data are supported:
Location Selection
The weather
and sensor
platforms automatically determine which weather station’s data to use. However, as station coordinates provided by Environment Canada are somewhat imprecise, in some cases you may need to override the automatic selection to use the desired station.
For these platforms, the location to use is determined according to the following hierarchy:
- Location ID specified in platform configuration (optional)
- Closest station to latitude/longitude specified in platform configuration (optional)
- Closest station to latitude/longitude specified in Home Assistant configuration (default)
The camera
platform dynamically builds imagery using a latitude/longitude as a center point. Radar station IDs are also supported for backwards compatibility.
For this platform, the location to use is determined according to the following hierarchy:
- Station ID specified in platform configuration (optional)
- Latitude/longitude specified in platform configuration (optional)
- Latitude/longitude specified in Home Assistant configuration (default)
Weather
The environment_canada
weather platform populates a weather card with Environment Canada current conditions and forecast data.
To add Environment Canada weather to your installation, add the following to your configuration.yaml
file:
# Example configuration.yaml entry
weather:
- platform: environment_canada
- The platform checks for new data every 10 minutes, and the source data is typically updated hourly within 10 minutes after the hour.
- If no name is given, the weather entity will be named
weather.<station_name>
. - The platform automatically determines which weather station to use based on the system’s latitude/longitude settings. For greater precision, it is also possible to specify either:
- A specific station code of the form
AB/s0000123
based on those listed in this CSV file, or - A specific latitude/longitude
- A specific station code of the form
Configuration Variables
Part of a set of coordinates to use when finding the closest weather station.
Part of a set of coordinates to use when finding the closest weather station.
The station code of a specific weather station to use. Station codes must be in the form AB/s0000123
, where AB
is a provincial abbreviation and s0000123
is a numeric station code. If provided, this station will be used and any latitude/longitude coordinates provided will be ignored.
Sensor
The environment_canada
sensor platform creates sensors based on Environment Canada current conditions and alerts.
To add Environment Canada sensors to your installation, add the desired lines from the following example to your configuration.yaml
file:
# Example configuration.yaml entry
sensor:
- platform: environment_canada
- A sensor will be created for each of the following conditions, with a default name like
sensor.temperature
:-
temperature
- The current temperature, in ºC. -
dew_point
- The current dewpoint, in ºC. -
wind_chill
- The current wind chill, in ºC. -
humidex
- The current humidex, in ºC. -
air_quality_health_index
- The current Air Quality Health Index score -
pressure
- The current air pressure, in kPa. -
tendency
- The current air pressure tendency, e.g., “Rising”. -
humidity
- The current humidity, in %. -
visibility
- The current visibility, in km. -
condition
- A brief text statement of the current weather conditions, e.g., “Sunny”. -
icon_code
- A two-digit number corresponding to a condition icon, as specified in these image to description and code to description mappings. -
wind_speed
- The current sustained wind speed, in km/h. -
wind_gust
- The current wind gust, in km/h. -
wind_direction
- The current cardinal wind direction, e.g., “SSW”. -
wind_bearing
- The current wind direction in degrees. -
high_temperature
- The next forecast high temperature, in ºC. -
low_temperature
- The next forecast low temperature, in ºC. -
uv_index
- The next forecast UV index. -
chance_of_precip
- The next forecast probability of precipitation, in %. -
forecast
- A textual description of the next forecast period, e.g., “Tonight. Mainly cloudy. Low -12.” -
precipitation_yesterday
- The total amount of precipitation that fell the previous day. -
warnings
- Current warning alerts. -
watches
- Current watch alerts. -
advisories
- Current advisory alerts. -
statements
- Current special weather statements. -
endings
- Alerts that have recently ended.
-
- The platform automatically determines which weather station to use based on the system’s latitude/longitude settings. For greater precision, it is also possible to specify either:
- A specific station code of the form
AB/s0000123
based on those listed in this CSV file, or - A specific latitude/longitude
- A specific station code of the form
- In the case of multiple alerts in the same category, the titles of each are concatenated together with a pipe (
|
) separator.
Configuration Variables
Part of a set of coordinates to use when finding the closest weather station.
Part of a set of coordinates to use when finding the closest weather station.
The station code of a specific weather station to use. If provided, this station will be used and any latitude/longitude coordinates provided will be ignored. Station codes must be in the form of AB/s0000123
, where AB
is a provincial abbreviation and s0000123
is a numeric station code.
Language to use for entity display names and textual data (English or French).
Alert TTS Script
If you would like to have alerts announced via a text-to-speech service, you can use a script similar to the following:
weather_alert_tts:
sequence:
- service: tts.amazon_polly_say
data:
message: "{{ states('sensor.warnings') }} in effect."
Camera
The environment_canada
camera platform displays Environment Canada meteorological radar imagery.
To add Environment Canada radar imagery to your installation, add the desired lines from the following example to your configuration.yaml
file:
# Example configuration.yaml entry
camera:
- platform: environment_canada
- If no name is given, the camera entity will be named
camera.environment_canada_radar
. - The platform dynamically builds imagery based on a latitude/longitude center point. This center point can be specified using:
- The latitude/longitude of the Home Assistant installation (default)
- A specific latitude/longitude for the platform (optional)
- A specific radar station ID from this table. The code must be in the form
XXX
orCXXXX
, i.e., remove the leadingC
only if the result forms a three-letter code, otherwise, include it. Valid values includeXFT
for Ottawa orCASBV
for Montreal. (optional, for backwards compatibility)
Configuration Variables
The station code of a specific radar station to use. If provided, this station will be used and any latitude/longitude coordinates provided will be ignored. Must be in the form XXX
or CXXXX
.
Boolean setting to determine whether to display an animated GIF of images from the last 2 hours. If false
, the latest still image will be displayed.
