How to add network of 10 weather station fron weatherlink



  • It is possible to add 10 weather stations vantage pro 2 plus to windy?


  • Meteorologist

    There are many software options to upload to Windy when using a Davis station. You mentioned Weatherlink but I'm unsure if you are referring to Weatherlink.com or the new WeatherLink Live device. Either way you might need to add some hardware/software to upload to Windy.

    As for uploading from a network of 10 VP2 hardware it depends on the software used as there are several options. It might require a separate Windy account (email) for each device. I do know of a way with the Meteobridge for example to upload to Windy from several stations using the same account. It requires sending data to Windy using the HTTP upload method with custom URL instead of using the built in Windy upload. This is because the default Windy upload defaults to station=0 which is your first listed Windy station ID on your Windy account. So to specify upload to a different Windy ID you use the custom HTTP upload method and then change the "station equal statement" to match the matching ID for example station=3 in the HTTP upload. It is possible to probably do this with other weather software but you'd have to research or ask. Check with the following other software to see how to change the station= upload with these other various software; Weather-Dispaly, Cumulus MX, WeeWx. For information on how to do this with Meteobridge here is a relevant link:

  • Weather Stations send data to weatherlink.com via WeatherLinkIP


  • Meteorologist

    The WeatherLink IP alone is not going to help you send data to Windy.

    I recommend you run one of the following software that will read data from the WeatherLink IP in order to then send it to Windy. (listed in no special order). Which means you need a device on that local network to pickup data from the WeatherLink IP. This could be a Raspberry Pi in the case of some of this software or in case of the Meteobridge it is its own small device.

    • Meteobridge
    • Weather-Display

    Another thought.... remember with WeatherLink.com you can send your data to CWOP. All CWOP stations automatically show up on Windy without you needing to open a Windy account nor do anything on the Windy side. So that is just another option. Data from CWOP is delayed 10 minutes and compared to a station that sends data directly to Windy then that is only delayed 5 minutes. So there is an advantage to uploading directly to Windy rather than via CWOP. Another advantage to sending directly to Windy is that only then does it give a forecast.

    @glez_b Hi, you can use suggested solutions by @galfert. Alternatively, you can use WifiLogger or a python script which I am enclosing below:

    Newest Meteobridge update now supports custom station ID uploads. Basically it now supports &station=X standard.
