Froggit Weather Station Protocols for Custom Server

This documentation explains how to receive data from a Froggit weather station using your own server. It covers two protocols: Ecowitt (POST requests) and Wunderground (GET requests).

Hardware:

DP2000 7-In-1 Y-Edition Wifi/Lan Wireless Weather Station: Product Link
It is recommended to put the Gateway into a VLan

Setup

Power the Gateway: Connect the Gateway to a power source, and after a short period, a new Wi-Fi network (GW2000X-WIFIXXXX) should appear.
Connect to the Gateway’s Wi-Fi: Use the Gateway’s Wi-Fi to connect and open 192.168.4.1 in your browser.
Select Connection Type: In the “Local Network” tab, select your preferred connection type: WiFi or Ethernet (via cable).
Configure Protocol: Under the "Weather Services" tab, choose the desired protocol type: Ecowitt or Wunderground.

Ecowitt Example:

Wunderground Example:

PHP Code

The both.php file supports both Ecowitt and Wunderground protocols.

PHP Code Overview

The provided PHP code extracts data from incoming POST (Ecowitt) and GET (Wunderground) requests and normalizes the values before storing them into an SQLite database.

Key Mapping from Wunderground to Ecowitt:

$WUNDERGROUND_TO_ECOWITT = array(
    'tempf' => 'tempf',
    ...
);

Conclusion

This setup allows you to receive weather station data from either Ecowitt or Wunderground protocols, process it on your custom server, and store the data in an SQLite database for further analysis. The PHP code provided normalizes the data and ensures compatibility with both protocols.
