Hello @Rob_Malschaert,
A 429 error typically means too many requests—Wallbox may be rate-limiting API calls from the Homey app. This can happen after repeated polling or failed authentications. Try waiting a few hours, then re-authenticate your Wallbox account in Homey. If the issue persists, it’s likely a temporary API restriction on Wallbox’s side—worth reporting to both Homey and Wallbox support for resolution. You’re not alone—others have seen similar issues recently.
Best Regards,
Amy Cross
Thanks for the reply.
The re authentication did not work. I am going to raise the issue with Wallbox. I believe the Wallbox update is the issue
Thanks for this github link. Exactly what I needed.
I build a flow for my charger (not wallbox, but the flow should still be usable).
I am very satisfied with the way it uses all my solar surplus. (My meter is on ~300W, which more or less matched the resolution (1A=220W)
You can read and doenload it here
I also have this 429-error.
I’ll wait until @rkokkelk has made a new test version available: he is working on it.
To help him I am sending a “cup of coffee” to him … 
Many thanks for fixing the app Roy!
