Step 0: check whether your station is WOW-ready

A “WOW-ready” station has an interface (app or web) that allows a custom upload and supports one of the following protocols: WOW-UK, Weather Underground or Ecowitt. Such a station can send data to WOW-BE.

Examples: Eurochron EFWS2900 (with the WS View or WS View Plus app; also sold as Garni 940, Alecto 5500 and Ventus W830), Ecowitt stations with an internet connection (with the Ecowitt app).

Have you managed to connect a different station to WOW-BE? Let us know via the contact form and we will add it to the list.

Step 1: register as a user

Create an account under “Login” or at wow.meteo.be/web/login.

Step 2: register your station

Log in and choose “Register a station”. You will receive the station ID (long and short version) and the authentication key you chose yourself by email.

Step 3: configure your station

In the app or software of your station, look for the option to set up a custom upload (sometimes called “DIY Upload Servers”). Choose “Customized” as the server (so not “WeatherObservationsWebsite”). Set the upload interval to 1 minute.

Wunderground protocol

• Server: wow.meteo.be
• Path: /api/v2/send?
• ID: short station ID from the registration email
• Key: your self-chosen authentication key
• Port: 80

Ecowitt protocol

• Server: wow.meteo.be
• Path: /api/v2/send?
• Port: 80

The Ecowitt protocol uses your station’s MAC address as identification — no ID or key required. Enter the MAC address when you register your station (or add it later).

Stations without a configurable upload path

On some stations, such as the Bresser 8-in-1 and devices using the WSLink app, the upload path cannot be changed. For these stations, use the Wunderground protocol with server towowbe.dev, your short station ID, your authentication key and port 80. This is a temporary solution; a permanent solution is being investigated.

Step 4: check the connection

Check your personal dashboard to see whether data is being sent. Your station will appear on the map a few minutes later.

WOW Met Office will be discontinued at the end of 2026. To connect your station to WOW-BE, you need to register it again on the RMI’s WOW-BE platform. Your station’s measurement history cannot be transferred: on WOW-BE, your station starts with a clean slate.

The upload protocol is identical to that of WOW Met Office, except for air pressure measurements: the parameter ‘baromin’ is now always interpreted as relative air pressure (i.e. pressure reduced to sea level).

Step 1: register as a user

Create an account under “Login” or at wow.meteo.be/web/login.

Step 2: register your station on WOW-BE

Log in and register your station. After registration, you will receive by email a new station ID (short and long version) and your self-chosen authentication key, which replaces the old six-digit PIN. The station ID is not the same as the ID of your station on WOW Met Office.

Step 3: update the endpoint and station details

Change the upload endpoint from http://wow.metoffice.gov.uk/automaticreading? to http://wow.meteo.be/api/v2/send?

Most weather software supports WOW-BE in recent versions. Look specifically for “WOW-BE upload” in the software.

Use your new station ID (short or long version) and your authentication key here.

Step 4: check the connection

Check your personal dashboard to see whether data is being sent. Your station will appear on the map a few minutes later.

You can also use the API yourself to connect your station. Full documentation: wow.meteo.be/docs/api

Take into account these important changes compared to the WOW Met Office protocol:

• The solarradiation parameter has been added.
• rainin is interpreted as rainfall intensity in inches/hour for all protocols.
• baromin = relative pressure; absbaromin = absolute pressure. baromin is the authoritative value: if both are supplied, only baromin is used; if only absbaromin is supplied, the relative pressure is derived from it.

The placement of your station is at least as important as the quality of the sensors. Please try to follow these guidelines:

• Temperature: place the thermometer in an open, well-ventilated location, away from buildings and other heat sources.
• Wind: place the anemometer as far as possible from buildings, trees and other obstacles.
• Precipitation: place the rain gauge in an open location, away from obstacles.
• Humidity: a difference of a few percent between sensors is normal. In fog above freezing, relative humidity should be close to 100%.
• Air pressure: no specific placement requirements.

If your weather station consists of a single unit (a so-called sensor array), look for a compromise between the guidelines above. More information about placing your weather station can be found under FAQ.
