Why get a bus id?

A bus id is used to provide identification when a PJON bus is directly connected or sharing its medium with others. To make sure that the bus id you use is unique, and not the same used by your neighbour, get a unique official bus id released here filling in the form below. The use of a bus id enables to control devices securely but also to communicate with other makers nearby. It is finally possible to setup a private, decentralized physical network infrastructure and anonymously connect to each other without an internet connection.
