1. An electronic device for use in a lighting system for rendering emergency lighting, said electronic device comprising:
at least one communication interface; and
at least one processor configured to:
detect a switch from a normal mode of said lighting system to an emergency mode of said lighting system and a switch from said emergency mode to said normal mode,
activate an emergency radio frequency-based sensing function upon detecting said switch from said normal mode to said emergency mode, and
deactivate said emergency radio frequency-based sensing function upon detecting said switch from said emergency mode to said normal mode;
wherein said emergency radio frequency-based sensing function comprises using said at least one communication interface to receive radio frequency signals and inferring motion or presence of people by detecting disturbances to a radio frequency field affected by a human body, based on said received radio frequency signals.
