Introduction
Automatic Packet Reporting System / Citizen Weather Observation Program
With your existing weather sensors, gather the data with flows and send weather reports to the world-wide network as a radio amateur (licensed call sign required) or using Citizen Weather Observation Program (CWOP free registration required).
Note, that your Homey location is used to set your weather station’s geo-location and published to the service together with the weather report.
Device: Weather Station
For the Weather Station to be able to send weather reports to APRS-IS servers, you need have either an amateur radio call sign or apply for a Citizen Weather Observation Program ID for free.
Once you have a call sign, you can setup the device:
- Callsign
- Passcode (Only for amateur radio call signs)
- APRS Tier-2 Region (CWOP stations will always use Citizen Weather Observation Program)
Supported flow cards
Then - Action
- Set temperature to
Temperature. - Set humidity to
Humidity. - Set barometric pressure to
Pressure. - Set rainfall to
RaininUnits.- Rain measurements are internally evaluated to hourly, last 24 hour and since midnight values.
- Set wind speed to
Wind speed, gust speed toGust speedinUnitsand direction toWind angle.
For rain and wind values you will need the choose the units (mm or in of rain and m/s, km/h, mph or knots for wind speed). Bold are Homey internal defaults.
With these action cards you can take the values from your existing weather sensors and apply them to this Weather Station device, which then transmits them to APRS-IS.
At this time I do not have wind instruments so I’m not updating the wind information. This serves as a hint on how it works:
WindGust is optional and can be skipped.
