Based on the dimming setting, an output circuit generates a dimming control signal for application to a conventional dimming interface of a lighting driver circuit.

This provides a simple to use way to implement a controllable brightness, which makes use of a dimming driver but used for a luminaire which does not need to be within a networked dimmable system architecture.

Abstract: A wired switch allows switching the power supplied to a wirelessly controllable appliance, such as a lamp, which may be controlled by e.g. a smart phone running an app. A wireless switch is retrofitted to the wired switch. The wireless switch comprises one or more sensors arranged to detect both the position of the wired switch and a touch input. A controller, receiving indications based on said detection, determines a reachability of the wirelessly controllable appliance. The controller then associates an OFF command to the area of the wired switch that would normally be pressed to turn the lamp off. This allows the lamp to be turned OFF, when the wired switch is in the ON position, by a user controlling the wired switch as (s)he normally would without the used needing to actually change the position of the wired switch (thereby turning OFF power to the appliance).
