If your concern is not only about home security but about using motion to turn on or off the light, well, SONOFF SNZB-03 maybe makes you feel amazing.
This Zigbee motion sensor is an extra-handy smart device for placing anywhere in your home to detect motion and trigger alarms. That means the sensor will send an instant alert notification to your mobile phone whenever the motion is detected if this security system is armed. If you have a SONOFF ZBBridge, you can connect the sensor to it to activate Wi-Fi devices, not merely Zigbee devices. For example, you can set a scene for your living-room light so that it will automatically turn on when you walk through the living-room.
The new camera feature is used to make you know who is approaching your home and capture the video ever earlier than before. Boasts 110°view field and 6m detection rang and you can early receive an alert message of someone’s presence, accordingly taking measures to reduce the possibility that your house is threatened. Share control is available for multiple users to check and monitor your home together. Easy and tool-free installation, 3M adhesive installation significantly saves your time. Powered by the battery which is convenient to stick it on any place that you want to monitor.
Integrated effortlessly into Home Assistant using Zigbee.
The sensor itself works great as advertised in indoor settings. Its a pretty standard PIR motion sensor that connects via zigbee and has a fast response time. Im using it to tuen my office lights on as I walk in in the morning and its been pretty solid l.
I recently installed a couple of these to automate hallway lighting. I have two as this hall has a 90' turn and I wanted the lights to come on no matter which direction people entered. They have good field of view and are simple. Easy to setup in ewelink, easy to use and seem reliable to trigger. They are smaller than I imagined form the picture which is good. I did not want a large device drawing attention to itself. Small and inconspicuous was the goal. So far, these have been perfect. I plan to purchase and incorporate more.
Connecting to Home Assistant (ZHA) was easy. (That’s not true for sensors of other brands, generally speaking.)
I have the sensor a couple of weeks now, and it has been working reliably all the time. Battery is still at 100%
Only reason for not giving 5 stars is that it does not include an illuminance sensor. If they add that, it will be the perfect sensor.
Works great to trigger a night light when my toddler gets out of bed at night.
This is a nice motion sensor and works with Homeassistant (HA)(via zigbee2mqtt). But timeout between the detection can not be adjusted - big flow. Basically this device will not report multiple motion which happens within 2m of the detection. E.G.After receiving motion signal, if HA turns on corridor light for 30sec, and someone walk by in corridor after 30 sec, no detection! There should be a switch to control sleep time or to turn it off.
I've installed two Zigbee motion sensors to trigger automations in Home Assistant and both have worked flawlessly. I've ordered a third for another project.
I bought a SNZB-03 with the USB dongle and tow Door/Window sensor and a Temp/Humidity sensor. Every other sensor is working smoothly and never failed. but this Motion sensor is sadly crap. gets unavailable very often and you need to re-pair it in order to get it work again. only for it to fail again in a few hours. after some research (too bad I didn't do that before buying) i realize this is a common situation with this sensor. So, i do recommend the SNZB-04 and SNZB-02. but DONT BUY THE SNZB-03
I can only compare it with the IKEA Motion Sensor - main difference is the Sonoff one seems to have little larger range (both in distance and angle) and slightly faster detection time. It's also significantly smaller. I have it paired via Home Assistant (ZHA) and haven't experienced any reliability issues after several weeks.
Minor negatives are that it's very difficult to open (to pair or exchange batteries) and has limited mounting options (e.g. no screw mount like the IKEA sensor) - it comes with double sided sticker, but I don't want that in my wall, so I had to 3D print a wall mount.
A ZigBee end device is only as good as the Coordinator. I am using this with the ZigBee 3.0 Dongle plus and the results are excellent. No delay, no dropped connection and best of all battery life of more than a year if used correctly. Overall a 10/10. Excellent for Home assistant and can be used with Google home via Home assistant.
