Sonoff SNZB-03P Zigbee PIR motion sensor with ambient light detection

Walk in and the light is already on: the SNZB-03P PIR fires within 5 seconds, covers 6 m at 110° and runs over 3 years on one CR2477 cell; automations live on a Zigbee 3.0 hub.

Sonoff SNZB-04P Zigbee door and window opening sensor

By day the SNZB-04P flips on the hallway light as the door opens; with the flat empty it turns guard and pushes an instant alert — automations call for a Zigbee 3.0 coordinator.

No one ever wired a switch by the bed — the SNZB-01P adds one without opening the wall: an adhesive plate holds it magnetically, or it simply lies on the nightstand.

A single-channel Zigbee 3.0 relay that hides in the back-box behind the key and keeps the light on a local mesh through a Tuya Zigbee gateway, off the home Wi-Fi.

Stick the two halves on the door and frame: the moment the door or window opens, the ZDS16 sends a Zigbee alert to your phone.
