Easee EV Charger - tomnord - 15.04.2021
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?
https://github.com/fondberg/pyeasee
Regards..

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:
request_body= json.encode({
userName = 'aaa',
password = 'bbb',
})RE: Easee EV Charger - tomnord - 15.04.2021
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.
RE: Easee EV Charger - admin - 16.04.2021
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 :-)
RE: Easee EV Charger - tomnord - 28.01.2022
Works like a charm. I'll post when I have access to my LM again.

Hi soo exaited about this!
Will you post it? Or sent it on PM?
Thanks

Here is a script I use at a client's company to visualize the current charging power at each charging point in their company parking lot. Thank you tomnord for the earlier scrips
