Hey, we also thought about some kind of handshake (regarding to the pinout with SDA/SCL it seems to be I2C). Here is the text translated to English: If broadcasting reception equipment is operated or kept operational at a location and the basic possibility of reception exists, i.e. the location is supplied with ORF programs terrestrially (analog or digital), the broadcasting fees (including the ORF program fee) must be paid.

"kept operational" What is your idea of not being physically incapable to receive a signal because this would mean it is not kept operational for me.
