Compatible with major Zigbee hubs and voice assistants like Alexa and Google Home, it supports local smart scenes that function even during WiFi outages. Beyond automation, it enhances home security by triggering alarms, cameras, and instant notifications, making it an essential upgrade for any smart home enthusiast. ## Description SNZB-03P is a low-power motion sensor based on Zigbee3.0 protocol. Supports smart scenes to link with other smart devices, making it easy to turn on lights when people come and turn them off when people leave in places such as corridors, entrances, stairs... Compared with SNZB-03, SNZB-03P has improved performance, with detection duration as short as 5 seconds, smart environment light detection, and 3 years battery life. With local scene intelligent linkage, you can still activate Zigbee local scenes as long as your Zigbee devices are powered on even if the network is disconnected. Low latency, higher reliability. SONOFF SNZB-03P is compatible with multiple Zigbee hubs, such as SONOFF NSPanel Pro, SONOFF iHost, SONOFF ZB Bridge Pro, SONOFF ZBDongle-E, SONOFF ZBDongle-P and Echo Plus 2nd...expanding the possibilities for your home automation system. SNZB-03P can also be used for security purposes such as detecting unauthorized entry. It can trigger a camera to record a video, activate a sound alarm through the gateway, and send app notifications to alert you. Efficient auto-trigger responses and notification settings ensure the safety of your family and property. Review: Small but super slow - Unbelievably slow reaction time (around 5 sec); super long “freeze” period until it starts reacting after being triggered (60-90sec). Useless for proper automations. Review: Great motion sensor with limited ambient light reporting - This is a great, responsive motion sensor that also has an ambient light sensor built in (though not in the best implementation). This makes it perfect for use in automations where you want a light to turn on, only when a specified darkness level is reached. I was able to pair this up and incorporate it into my Home Assistant setup via zigbee2mqtt with no issues. It has performed exactly as expected and I've had no issues with the motion sensing. The ambient light sensor is nice to have (my previous motion sensors did not have one), but unfortunately the device only seems to report either "dim", or "bright". It would be much more preferable to have a numerical value reported so that you can customize your automations with more flexibility (e.g. the reported "dim" value might not be as dim as I would like). While better than not having a sensor at all, it's still a disappointing implementation. ## Features - 【5-Sec Faster Detection】Automatically turn the lights on immediately when you pass by, and turn off the light after you leave, the shortest time can reach 5 seconds, helping you save energy. - 【3-Year Battery Life】Powered by CR2477 battery extends the battery life to over 3 years, eliminating concerns about frequent battery replacements. - 【Zigbee 3.0 Compatible】Supports Zigbee hubs using the Zigbee 3.0 protocol, such as SONOFF NSPanel Pro, SONOFF iHost, SONOFF ZB Bridge Pro, SONOFF ZBDongle-E, and Echo Plus 2nd… - 【Local Smart Scene】Even if your WiFi network crashes, you can still activate Zigbee local scenes as long as your Zigbee devices are powered on. - 【Home Security】SNZB-03P can also be used for security purposes such as detecting unauthorized entry. It can trigger a camera to record a video, activate a sound alarm through the gateway, and send app notifications to alert you, and ensure the safety of your family and property. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C1GB4DVR | | Antenna Location | home security, automation, energy management | | Battery Average Life | 3 years | | Battery Description | Lithium, Coin cell | | Best Sellers Rank | #7,607 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #18 in Motion Detectors | | Brand | SONOFF | | Built-In Media | Sensor | | Color | white | | Colour | white | | Compatible Devices | SONOFF NSPanel Pro, SONOFF iHost, SONOFF ZB Bridge Pro, SONOFF ZBDongle-E, SONOFF ZBDongle-P, Echo Plus 2nd, Zigbee 3.0 compatible devices | | Customer Reviews | 4.3 out of 5 stars 726 Reviews | | EU Spare Part Availability Duration | 3 Years | | Item Dimensions D x W x H | 3D x 5W x 7H centimeters | | Item Type Name | SNZB-03P | | Item Weight | 58 Grams | | Item weight | 58 Grams | | Manufacturer | SONOFF | | Maximum Range | 19.7 Feet | | Maximum range | 19.7 Feet | | Mfr Part Number | SNZB-03P | | Model Number | SNZB-03P | | Mounting Type | Wall Mount | | Mounting type | Wall Mount | | Number of Batteries | 1 Lithium Metal batteries required.
