Facing a lot of 429 resoponse codes

Facing a lot of 429 resoponse codes

If you install an integration in a home energy management system, it may happen that the first call fails, e.g. due to incorrect settings (location, plane definition).

However, most integrations now regularly (sometimes every minute) try to send another API call!

If you use the Public API, the response code 429 will appear very soon, indicating that the rate limit has been reached.

In such cases you should

  • Deactivate/uninstall the integration
  • Wait at least 60 minutes
  • Check your parameters and preferably via direct API call (e.g. via curl)
  • If the direct API call works, reactivate/reinstall the integration
