One Presence Sensor for Several Living-Room Zones?
Zone-based sensing is attractive in an open room with distinct activities. Buy it with a room-layout and commissioning plan rather than expecting a product’s maximum zone count to design the space for you.

Draw useful zones
Mark the sofa, desk and passage rather than dividing every square into a new rule. Fewer meaningful zones can produce a clearer daily experience and make later adjustment easier for the household.
Check the proposed mounting
Ask how the planned position sees each activity area and deals with boundaries. The room’s geometry and furnishings matter, so include a current layout and photos rather than only a floor-area figure.
Connect zones to real actions
Name the lighting changes each zone should trigger and which should remain manual. Request a walkthrough with a person sitting in each location before accepting the configuration or ordering repeated rooms.
