Station Forwarder

This code is built to be hosted on the free Google Apps Script platform. It takes in weather station data from:

and periodically sends it on to


  1. Create a new Google Apps Script project and give it a name
  2. Overwrite the default file with from the latest release in this repository
  3. Configure the script for you:
  • Choose your datasource:

    IBM Wunderground

    Uses the IBM Wunderground API.

    Note: Unfortunately, it looks like the new Wunderground API keys have started expiring 6 months after being generated, so you may need to replace the key if that happens.

    • Set the datasource to ibm on line 10
    • Set your ibmAPIKey on line 12
    • Set your ibmStationId on line 13

    Experimental. Uses the undocumented MyAcurite private API.

    • Set the datasource to acurite on Line 10
    • Set your acuriteUsername on Line 15
    • Set your acuritePassword on line 16
    • Set your acuriteHubName (the user-set name on the internet-connected receiver) on line 17
    • Set your acuriteStationName (the user-set name of the outdoor sensor/station) on line 18
    Davis Weatherlink

    Uses the Davis Weatherlink API v2.

    • Set the datasource to davis on line 10
    • Set your davisApiKey on line 20
    • Set your davisApiSecret on line 21
    • Set your davisStationName on line 22
    Weatherflow Tempest

    Uses a Weatherflow Tempest Personal Use Token.

    • Set the datasource to weatherflow on Line 10
    • Set your weatherflowPUT on line 24
    • Set your weatherflowSationId on Line 25

    • Set the datasource to ambient on Line 10
    • Set your ambientWeatherStationName on line 27
    • Set your ambientWeatherApiKey on Line 28 (CWOP)

    Uses the API to fetch APRS packet data from a CWOP station.

    • Set the datasource to aprs on Line 10
    • Set your aprsStationID on line 30
    • Set your aprsApiKey on Line 31 from your account
  • and choose one or more forwarding destinations:

    IBM Wunderground

    To send to Wunderground:

    • Set updateWunderground to true on Line 35
    • Set your wundergroundAPIKey on Line 36
    • Set your wundergroundStationId on line 37

    To send to

    • Set updateWindy to true on Line 39
    • Set your windyAPIKey on Line 40
    • Set your windyStationId on line 41. It's likely 0, 1, 2, etc.
    Aeris PWSWeather

    To send to PWSWeather:

    • Set updatePWSWeather to true on Line 43
    • Set your pwsWeatherAPIKey from your station's profile page on line 44
    • Set your pwsWeatherStationID on Line 45

    To send to WeatherCloud:

    Retrieve your station's ID and API Key by going to your Devices, then clicking Settings → 🔌 Link on your station.

    • Set updateWeatherCloud to true on Line 47
    • Set your weathercloudAPIKey on Line 48
    • Set your weathercloudID on Line 49
    • Set whether or not you have a WeatherCloud Pro or Premium account with hasWeatherCloudPro as true or false on line 50

    Creation of a new OpenWeatherMap station must be done by API, not on the OpenWeatherMap website. More information is available in the OpenWeatherMap Station API documentation. The basic concept for what must be done is available in the createNewOWMStation_() function. Remove the _ character from the name of that function to make it selectable from the ▷ Run button in the toolbar. If you do so, make sure you note your new station's ID and other details in the log (available in the Executions tab in the sidebar after running!), then:


    Send to WindGuru:

    Start by registering a new "Other / Upload API" station, then:

    • Set updateWindGuru to true on Line 56
    • Set windGuruStationUID to your chosen station UID on Line 57
    • Set your windGuruStationPassword to your chosen station API password (note, not your account's password) on line 58
    NOAA Citizen Weather Observer Program (CWOP)

    Send to CWOP. Start by registering for a new station, then when you receive your email:

    • Set updateCWOP to true on Line 60
    • Set cwopStationIDOrHamCallsign to your assigned CWOP station ID that you received via email on Line 61
    • If you are using your ham radio callsign as your station ID and you have received a validation code from NOAA CWOP support, set cwopValidationCode to your validation code on Line 62
  1. Run the "Schedule" function with the ▷ Run button in the toolbar. You're done! You can see it periodically running in the ☰▶ Executions tab on the left sidebar. This code is executed on Google's servers and does not require a computer to remain on.

If you ever make changes to the API keys or enabled services, just run the Schedule function again.

How to Update

  1. Copy the code from in this release over your file.
  2. Make sure your API Keys and settings at the top of the file are correct and 💾 Save.
  3. Run the Schedule function again with the ▷ Run button in the toolbar.
