• Use the example parameters for your source (often available in the documentation) (don't forget to restart Home Assistant after changing the configuration)
• Checked that the website of your service provider is still working
• Tested my attributes on the service provider website (if possible)
• I have tested with the latest version of the integration (master) (for HACS in the 3 dot menu of the integration click on "Redownload" and choose master as version)

Checklist Sensor Error

• Checked in the Home Assistant Calendar tab if the event names match the types names (if types argument is used)
