Smart Weather UDP for Home Assistant

This a custom component for Home Assistant. It reads real-time data using the UDP protocol from a Smart Weather weather station produced by WeatherFlow.

As I don't have access to HW on my location, this Integration is no longer maintained by me. LuckyJayDIY (Mark Turner) has volunteered to fix bugs, as time allows. If any one else wants to volunteer, please send me a note.

v0.1.7 - Now has support for the Tempest Weather System!
The Tempest Weather System combines the functionality of the AIR and SKY units into a single device.

It will create several sensor entities for each weather reading like Temperature, Precipitation, Rain etc.

The smartweather component uses the WeatherFlow UDP API to retrieve current data for a local WeatherStation.

Notes:

1. As this component listens for UDP broadcasts, in can take up to 1 minute before all sensors have gotten a value after restart of Home Assistant
2. Precipitation values broadcasted from the unit is always current precipitation rate. That means that the value in the sensor precipitation is a calculated value. So if the system is restartet during the day, the value will be reset to 0. As long as the system is running this should be correct.
3. My setup is 1 AIR unit and 1 SKY unit. This component is only designed to work with one of each unit. But I would be glad to know what happens if you have more than one of each unit connected to the same base.

Installation

This Integration can be installed in two ways:

HACS Installation
Add the following to the Custom Repository under Settings in HACS:
briis/smartweatherudp and choose Ìntegration as Category

Manual Installation

1. If you don't already have a custom_components directory in your config directory, create it, and then create a directory called smartweatherudpunder that.
2. Copy __init__.py, manifest.json and sensor.py from this repository in to the smartweatherudp folder.
3. or using Git, go to the custom_components directory and enter:
   git clone https://github.com/briis/smartweatherudp.git

Track Updates

If installed via HACS, updates are flagged automatically. If you did a manual installation this custom component can be tracked with the help of the Custom Updater component.

In your configuration.yaml file add the following:

custom_updater:
component_urls:
  - https://raw.githubusercontent.com/briis/smartweatherudp/master/custom_updater.json

Configuration

Edit your configuration.yaml file and add the smartweather sensor component to the file:
Note If you don't add monitored_conditions then all sensors will be created.

Configuration Variables

wind_unit
(string)(optional) If Home Assistant Unit System is metric, specify kmh to get units in km/h. Else this has no effect.
Default Value: m/s if Home Assistant Unit System is metric, and mph if Unit System is imperial

host
(string)(optional) Default is 0.0.0.0 but you can enter any host IP. Typically used if your Weather Station is on a different Subnet than Home Assistant.

name
(string)(Optional) Additional name for the sensors.
Default value: SmartWeather

monitored_conditions
(list)(optional) Sensors to display in the frontend.
Default: All Sensors are displayed

• temperature - Current temperature
• dewpoint - Dewpoint. The atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form
• feels_like - How the temperature Feels Like. A combination of Heat Index and Wind Chill
• heat_index - A temperature measurement combining Humidity and temperature. How hot does it feel. Only used when temperature is above 26.67°C (80°F)
• wind_chill - How cold does it feel. Only used if temperature is below 10°C (50°F)
• wind_speed - Average Wind Speed in the last minute
• wind_bearing - Average Wind bearing in degrees for the last minute (Example: 287°)
• wind_speed_rapid - Current Wind Speed (Updated every 3 seconds)
• wind_bearing_rapid - Current Wind Bearing in degrees (Updated every 3 seconds)
• wind_gust - Highest Wind Speed in the last minute
• wind_lull - Lowest Wind Speed in the last minute
• wind_direction - Average Wind bearing as directional text for the last minute (Example: NNW)
• precipitation - Precipitation since midnight
• precipitation_rate - The current precipitation rate - 0 if it is not raining
• humidity - Current humidity in %
• pressure - Current barometric pressure, taking in to account the position of the station
• uv - The UV index
• solar_radiation - The current Solar Radiation measured in W/m2
• illuminance - Shows the brightness in Lux
• lightning_count - Shows the numbers of lightning strikes for last minute. Attributes of this sensor has more Lightning information.
• airbattery - The current voltage of the attached AIR unit
• skybattery - The current voltage of the attached SKY unit

NOTE: The Tempest Weather System will return its battery voltage in BOTH the airbattery and skybattery sensors
