Easee EV Charger

[tomnord]

Hello, any ideas on how to integrate this? 

https://api.easee.cloud/index.html



I've found a Python script on github, is it possible to convert this in any way?

This is a similar API: https://forum.logicmachine.net/showthread.php?tid=1786
There's a difference in login procedure (GetToken function). You need to set the 'content-type' header to 'application/json' and send username/password as json string:

Code:

1234

request_body= json.encode({   userName = 'aaa',   password = 'bbb', })

Thanks, it works.

What would be the best way if i wanted the connection to the API to stay active, and then run seperate scripts for various commands?
It's not best practise to request new tokens for every command.

[admin]

Create a scheduled script that will call GetToken() periodically and save the token into storage. All other scripts will use this token to make requests.
Check the expiresIn field that /api/accounts/token returns. It will tell for how many seconds the token is valid. Adjust scheduled script execution period accordingly.

Did you get your script to work?

Are you willing to share your script and the commands for the Easee charger?

that would be very nice and would save me a lot of time :-)

Works like a charm. I'll post when I have access to my LM again.
