You have to fill in the license plate number without center line, otherwise it doesn’t work.

Thank you for your feedback @Jacques_Derks.

This is an initial version, I’ll try and get around to adding some validation and error handling when adding a licenseplate/vehicle.

If you see anything interesting here that you’d like in the app, let me know.

A check for if there is any open recall operation (openstaande_terugroepactie_indicator) was already mentioned and will be added in the next update.

Latest test version adds a new capability, new flow triggers and flow conditions.

New capability:

  • Open recall (“Ja”/“Nee”)

New flow triggers

  • The APK expiry date has changed
  • There is a recall

New flow condition:

  • Has open recall

I’ve identified an error regarding the flow card “The APK expiry date has changed”. I’ll need to further investigate the issue and will post any updates here.
