Control events in a system of networked home devices

A method of handling control events in a system of networked home devices, the method comprising, at a controller:

• receiving a signal indicative of a control event, the control event being an actuation of a user input device;
• and
• in response to the control event, determining whether to perform a control function associated with a networked home device of the system, that determination being made in dependence on a state of interaction between the networked home device and a physical environment in which it is located at a time of the control event;
• wherein the controller makes said determination by determining whether performance of the control function would cause a significant change in the state of interaction;
• and
• if the performance of the control function would cause a significant change in the state of interaction, the control function is performed in response to the control event, it causes the networked home device to perform an action that changes the state of interaction between the networked home device and the physical environment in which it is located,
• if the performance of the control function would not cause a significant change in the state of interaction, the control function is not performed in response to the control event, the controller causes another control function associated with a different networked home device of the system to be performed in response to the control event instead.
