Overview / Docs

 
After its insolvency in Oct. 2019, Bonaverde disappeared from the scene and left thousands of Berlin users alone with the airfilter reset problem.
The problem has been solved in 2020.

The combined effort of a few resourceful and competent Berlin(ers) who had come together in a facebook group has finally led to the development of an app that allows you to create RFID tags to control the Berlin yourself.

The raw material required is commercially available writeable tags of the type "Mifare Ultralight EV1".
The cards are available at a reasonable price, for example, here:
But it also works with scans from Bonaverde that have not yet been used.

The app called VerdeNFC works perfectly and can be installed for free via the Google Play Store.
Link to the app:

The Apple version can only be used with iOS 13 or higher due to technical requirements.
Link to the app:
Since Apple collects high fees, this version unfortunately costs about 2€.
(... "it has always been a bit more expensive to have a special taste" 😆)
