Eelink GPT18
Flespi parses telemetry data from your Eelink GPT18 into a standardized JSON and
lets you send commands to Eelink GPT18 via API.
Here’s the like of JSON you get
{
"ident": "352625333222111",
"position.altitude": 273.61,
"position.hdop": 0.7,
"position.latitude": 49.069782,
"position.longitude": 28.632826,
"position.satellites": 18,
"server.timestamp": 1650636570.426424,
"timestamp": 1650636570.426424,
"device.type.id": "Eelink GPT18",
"channel.id": 1111,
"protocol.id": "eelink"
"engine.ignition.status": true
...
}
How to consume this nice JSON
The easiest way is to make a REST API request like this
curl -X GET --header 'Authorization: FlespiToken XXX' 'https://flespi.io/gw/devices/<device id>/messages'
You can also
Modify messages
Add or remove parameters, inject data from LBS and reverse-geocoding services, etc.
Learn what plugins can do
Aggregate data
Determine trips and stops, catch events, detect geofence ins/outs, and more.
