Universal powerline bus

Universal Powerline Bus (UPB) is a proprietary software protocol for power-line communication between devices used for home automation. Household electrical wiring is used to send digital data between UPB devices via pulse-position modulation.[1]

Communication can be peer to peer, with no central controller necessary.[2]

UPB addressing allows 250 devices per house and 250 houses per transformer, allowing over 64,000 total device addresses, and switches can co-exist with other powerline carrier systems within the same house.[3][4]

While UPB may be more efficient than X10, it has far fewer products available on the market.[5]

Interoperability

As of 2017, control of UPB devices is partially supported by the openHAB software project.[6]
