Distributed system of home device controllers
A home device controller can monitor published state data on a message bus of a distributed system of home device controllers, the published state data indicating current states of home devices connected to each home device controller of the distributed system. The home device controller can detect, from the message bus, a fault condition corresponding to a specified home device controller in the distributed system of home device controllers. Based on the fault condition and a set of acquisition rules, the home device controller acquires a home device in the local network of the specified home device controller in the distributed system. Based on the published state data on the message bus, the home device controller maintains a current state of the acquired home device.

make a determination as to an ability of the first home device controller to acquire the first home device, as compared to each of the home device controllers of the remaining set, wherein making the determination includes determining at least a relative wait time in acquiring the first home device by the first home device controller as compared to one or more of the home device controllers of the remaining set; and

7 . A method performed by one or more processors of a first home device controller of a distributed system, the method comprising:
monitoring published state data on a message bus of the distributed system of home device controllers, the first home device controller operating as part of the distributed system of home controllers, the published state data indicating current states of home devices connected to each home device controller of the distributed system;
maintaining a data store that identifies the current state of each home device and home device controller of the distributed system, the current state for at least a first home device of the one or more home devices indicating an adjustable parameter for operating the first home device;
detecting, from the message bus, a fault condition corresponding to a specified home device controller in the distributed system of home device controllers, the specified home device controller being connected to the first home device;
making a determination as to an ability of the first home device controller to acquire the first home device, as compared to each of the other home device controllers of the distributed system, wherein making the determination includes determining at least a relative wait time in acquiring the first home device by the first home device controller as compared to one or more other home device controllers of the distributed system; and
based on the determination, acquiring and operating the first home device in its current state, so that the adjustable parameter for operating the first home device is not changed after the first home device controller acquires the first home device.
8 .

9 . The method of claim 7 , further comprising:
detecting, via the message bus, that the specified home device controller is back online; and

10 . The method of claim 7 , wherein the first home device includes at least one of a light element, an electrical outlet, a door lock, a garage door, a doorbell, a video camera, a cooking appliance, an audio system, a temperature control system, a window shade actuation system, a fan controller, a television, a sprinkler system, or a security system.
11 . The method of claim 7 , wherein making the determination includes determining a wireless transmission latency for the first home device controller to communicate with the first home device.
12 . The method of claim 7 , wherein the specified home device controller comprises a touch surface, and wherein the first home device controller remaps at least one gesture input that was previously performed on the touch-surface of the specified home device controller.
13 . A non-transitory computer readable medium storing an instruction set that, when executed by one or more processors of a first home device controller in a distributed system of home device controllers, cause the first home device controller to:
