Use the package manager pip to install latest version of python-socketio i.e v5.
pip install python-socketioIts needs to have the "Requests" installed to work
pip install requestsimport socketio
sio = socketio.Client()
#put your Token below and make sure you keep the "Bearer " as it is.
token = 'Bearer <YOUR TOKEN GOES HERE>'
#put your charger Id here
chargerId = '<YOUR Charger ID GOES HERE>'

- When we turn on the charger by calling the API
https://library.vecharge.app/api/v1/charger/chargerDesiredStateWe will receive the socket log in the "statusChanged" event as
{"status":"ON"}And the charger will be turned ON.
- Once the charger is ON, Now we will periodically receive data logs about charger on the "newLog" event as follows :
{"deviceId":"veChargePoint0125896","voltage":"230.00","current":"7.00","power":"1577.80","energy":0.23,"createdAt":"2022-01-10T13:57:59.124Z","userId":"pulse-test-user","chargerId":"test"}This proves we are successfully connected to socket and will receive all logs as long as we are connected to internet.
- When we turn off the charger by calling the API (optional in case a user wants to pause the charger)
https://library.vecharge.app/api/v1/charger/chargerDesiredStateWe will receive the socket log in the "statusChanged" event as
{"status":"OFF"}And the charger will be turned OFF and charger & socket both will get disconnected and we will not receive any logs from the server socket.
Also, 5. When we call the disconnect api the charger will be turned off and charger & socket both will get disconnected and we will not receive any logs from the server socket.
