The Steinel True Presence COM2 v2 Bluetooth Mesh Recessed True Presence and Twilight Sensor Square White IP20 is compared with several alternative presence sensor models from the Steinel brand, such as True Presence COM1 V2, True Presence COM1 AP, TRUE PRESENCE COM1 Bluetooth Mesh IP54, IR Quattro HD-2 24m KNX V3.5, and HALLWAY KNX V3.5. All evaluated products are designed for building automation, lighting and climate control, and energy efficiency. The main differences between them lie in the mounting type (recessed versus surface-mounted), supported communication interfaces (Bluetooth Mesh, KNX, COM1, COM2), IP protection rating (IP20 or IP54), and specialized applications such as corridors or general-purpose rooms.
