SONOFF SNZB-04 Zigbee Smart Door Window Sensor Mini Door Alarm Sensor Work With SONOFF Zigbee Bridge For Smart Home Security
Note 1: SNZB04 must be used with Zigbee Bridge.
The wireless door/window sensor is essential for knowing who is coming in and out of your home, so it is most often used as part of smart security system.
SONOFF SNZB-04 is a Zigbee two-in-one wireless door/window sensor that can be put on your door or window to tell you with an alert notification if your door or window is opened or closed, adding an extra layer of security to your home. The sensor provides you the possibility to create a scene linkage of Zigbee and Wi-Fi devices. Both the opening and closing status of the door/window are synced on your mobile phone, no longer to think back whether the door/down is off or not. It is really useful and can help you turn on or off the light in the action. Works with SONOFF ZBBridge in harmony, you can set a scene to get your hallway lighted immediately when the door is opened.
The camera function can be enabled on the sensor page in the eWeLink APP, which also allows you to view clearly who enters your home; even you can frighten the stranger and ask him to leave your home immediately with the two-way audio function. Its application can also extend to wide areas like drawers, garage doors, blinds, etc. Just stick it anywhere two things connect and it is always safe even if you don’t keep watch on it. Share the sensor with your family to give them an ability to quickly control and monitor your home together. Simple installation for easier setup. Peel and directly stick it on the targeted place or object, a smart security system is ready for you.
The sensor takes too long to update the zigbee network with its state. Other devices update instantly on the very same network. The device blinks but state is not updated. I have a couple of those devices, replaced batteries, and it seems all have this problem on different rooms and close to different routers.
Sorry for the inconvenience, our customer service will contact you to help you solve this issue.
Paired easily and has been working great for weeks. Using with zigbee2mqtt and connected to home assistant. Smaller than other contact sensors I've purchased in the past which is nice.
After trying both the DW2-WiFi (slow response and terrible battery life) and DW2-RF (faster, better battery life, but does not give both open and close events). This version has the best of aspects without the drawbacks. Only downside is the need for a ZigBee hub. Physical size of these is also smaller then the Wifi or RF versions.
What differentiates this sensor from all the others on the market is that they work first time and are reliable. The sensor is a breeze to configure and if you are thinking about a Zigbee window/door sensor, this is the way to go. It's a pity that its the only unit in the range that uses a CR2032 battery while all the other units use a much longer life battery. Of course, because it reports the battery life, you can easily setup routines to pre-advise you about the need for battery replacement. They did a great job with this sensor. I have been using the Sonoff products for many years and have installed hundreds of their units. Their Zigbee products are great, easy to set up and are a breeze to integrate with Home Assistant or to flash new hardware. Over time they have proven to be reliable and value for money and have proven that they have heard their customers and what they want.
