WeatherFlow Cloud

The WeatherFlow Cloud integration provides access to cloud provided Weather Forecast of a user’s Tempest Weather Stations. In order to access the station, you will need to configure the integration with an Api Key.

Which integration(s) should I use

There are two integrations for WeatherFlow devices, and you are not limited to selecting just one.

  • WeatherFlow is a local only UDP-based integration that will read data directly from the device. This integration does require the Home Assistant server and the WeatherFlow device to be on the same subnet.

  • WeatherFlow Cloud is a cloud-based integration that closely mirrors the data available via the Weatherflow Tempest mobile applications and is likely a good starting place for most users as it provides both Forecast and Sensor data.

Configuration

To add the WeatherFlow Cloud integration to your Home Assistant instance, use this My button:

Manual configuration steps

If the above My button doesn’t work, you can also perform the following steps manually:

  • Browse to your Home Assistant instance.

  • Go to Settings > Devices & Services.

  • In the bottom right corner, select the Add Integration button.

  • From the list, select WeatherFlow Cloud.

  • Follow the instructions on screen to complete the setup.

Temperature sensors

Sensor Description
Dew point The temperature to which air must be cooled to become saturated with water vapor.
Feels like An index that combines temperature and humidity to determine the apparent temperature.
Heat index A measure of how hot it feels when relative humidity is factored in with the actual air temperature.
Temperature The degree or intensity of heat present in the area.
Wet bulb globe temperature A composite temperature used to estimate the effect of temperature, humidity, wind speed, and solar radiation on humans.
Wet bulb temperature The lowest temperature that can be reached under current ambient conditions by the evaporation of water only.
Wind chill The lowering of body temperature due to the passing-flow of lower-temperature air.

Air sensors

Sensor Description
Air density The mass per unit volume of Earth’s atmosphere.
Pressure barometric The pressure exerted by the atmosphere at the earth’s surface.
Pressure sea level The atmospheric pressure at mean sea level.
Pressure station The atmospheric pressure at the station level.

Lightning sensors

Sensor Description
Lightning count The total number of lightning strikes.
Lightning count last 1 hr The number of lightning strikes in the last hour.
Lightning count last 3 hr The number of lightning strikes in the last three hours.
Lightning last The most recent lightning strike.
Lightning last distance The distance of the most recent lightning strike.

Weather icons

There is not a straight 1-1 mapping between the Home Assistant supported weather conditions and what tempest provides - as such you may see a difference between what is displayed in the tempest app and what is displayed in Home Assistant.
