## Long description

HomeMatic HmIP-SWSD-2 is an optical wireless detector designed for integration with HomeMatic IP smart home systems. Powered by a 3 V lithium battery, the detector features a compact housing with a diameter of 11.5 cm and a height of 45 mm. It detects optical changes consistent with smoke or combustion particles and transmits alerts wirelessly to compatible HomeMatic IP hubs for alarm triggering, automation routines, and remote notifications. The device is lightweight and intended for ceiling or high-wall mounting in living spaces where rapid optical detection is required.
