Show a message triggered by the Google calendar on a KNX display to put out the garbage cans

Rubbish departure times are becoming more and more complex. Because of waste separation, each household has up to four bins, each with different emptying intervals, and because of public holidays there are shifts. It has become difficult to remember when to put out what. With this applet, it's easy. Once a year, enter all collection days in the Google calendar and be informed on your KNX display. Never miss an emptying again.
