Froggit weather station protocols for custom server

Example output and NodeJS server code snippet for a Froggit weather station when using an own custom server instead of predefined weather services.

My hardware:

• WH3000SE sensor
• DP1500 Dongle

Ecowitt protocol type

• HTTP method: POST
• Data: urlencoded body

Wunderground protocol type

• HTTP method: GET
• Data: query parameters

}

NodeJS code to try out

Here's a very basic server to retrieve the Froggit's data with.

Configure the following options in the weather station when trying it out:

• For Ecowitt protocol type
  • Server IP: [your machine IP]
  • Path: /data
  • Port: 3000
• For Wunderground protocol type
  • Server IP: [your machine IP]
  • Path: /data?
  • Port: 3000

var express = require('express');
var app = express();

app.use(express.urlencoded({ extended: true }));

//  Wunderground requests
app.get('/data', (req, res) => {
    console.log(JSON.stringify(req.query, null, 2));
    res.sendStatus(200);
});

//  Ecowitt requests
app.post('/data', (req, res) => {
    console.log(JSON.stringify(req.body, null, 2));
    res.sendStatus(200);
});

app.listen(3000, () => {
    console.log('ws-server listening on port 3000...');
});
