I wanted to be able to collect readings from my own GCM monitor into my own time series database so that I can do my own time series analysis and use my own visulaization tools and dashboards.
- This library was implemented based on work from khskekec which, was generously made available in this gist.
- I also use this
javascriptbased API implementation at https://github.com/DiaKEM/libre-link-up-api-client
Given below are full examples of command line utility implementations of getting the latest value and a range of values for graph data.
The following example shows you how to get the latest blood glucose value available. This is achieved simply with a call to login and then getting the available connections. The connections call will provide latest values without the need to make a 3rd call for historical data.
package main
import (
"fmt"
"github.com/danishm/gollu"
"os"
"time"
)
func main() {
if len(os.Args) < 3 {
fmt.Println("Error: Please provide email and password as command line parameters")
os.Exit(1)
}
email := os.Args[1]
password := os.Args[2]
// logging in
client := gollu.NewLibreLinkUpClient(email, password)
resp, err := client.Login()
if err != nil {
fmt.Printf("Error: %s\n", err)
os.Exit(-1)
}
// getting latest value
connections, err := client.Connections(resp.Data.AuthTicket)
if err != nil {
fmt.Printf("Error: %s\n", err)
os.Exit(-1)
}
fmt.Println(connections.Data[0].GlucoseMeasurement.Value)
os.Exit(0)
}$ go run latest.go foo.bar@test.com fakepassword
136The example below will make 3 calls to get a list of blood glucose values for the last 12 hours. This duration is the behavior I've seen so far by default.
- Call 1 - Make a request to login to acquire a bearer token
- Call 2 - Get a list of available connections to retrieve a
patientID - Call 3 - Retrieve the list of historical values, typically for the last 12 hours
This utility simply outputs the vales as a tab seperated values of [Timestamp, Value]
