A system for automation and control within a building, comprising a first actor node configured to operate within a wireless network, wherein the first actor node comprises:
- a receiver configured to detect data packets that are transmitted by other nodes configured to operate within the wireless network;
- a processor configured to:
- i) subscribe the first actor node to a first non-empty set of addresses, including a first space address that is representative of a first predetermined space within the building, wherein the first space address is stored in a memory, and
- ii) generate a control signal in response to detecting a first data packet in the data packets, only if the first space address is both a) received in the first data packet and b) subscribed to by the first actor node;
- and
- an output unit configured to perform a predetermined function based on the control signal.
