People have commented that it drops off frequently. I have found it to be design issue. If you open it up, you would find that the casing holding the battery is bit loose and allows battery t move around which, I am guessing, causing the connection drop. I got around this by wedging a piece of paper between battery steel casing and the plastic cover. It holds the battery in place and the sensor seems to be working ever since. It's been ~3 days only though.

Home Assistant- these work great, but Aqara is better
They work as expected, and setup within Home Assistant was painless. However, I recommend going with the Aqara contact sensors instead. The Sonoff ones are noticeably bulkier with sharper edges, so they stand out a little more and don’t blend in as easily as the Aqara ones. They also seem to be less sensitive than the Aqara sensors, so you have to get the pieces closer together to register a ‘closed’ signal. Under most circumstances this won’t be a problem, but if you have an older home with crooked door frames (like I do), those extra millimeters of flexibility make placement a lot easier.09/30/2022Verified Purchase
I had high hopes for this SNB-03 Motion Sensor, but, ...
The story regarding the Sonoff SNZB-03 ZigBee Motion Sensor did not start well, when removing the back to get to the battery was a great pain, then, the sensor did not initially connect after installing the battery and required a reset via the button behind the tiny hole (thankfully, I have a 0.6 mm probe). After reset, the sensor was connected to my Hubitat hub as, Generic Zigbee Motion Sensor (no temp), and it displayed a very good motion detection range throughout the day. For installation, instead of using the included adhesive tab, I 3D Printed a mount for it which I attached using VHB so that I could have easy access to the device. And what a good thing I did, as it appears that frequent access is necessary.
The next morning, the sensor gave a quick flash when motion was detected in the area, but no trigger was logged on the hub. I tried the available ‘configure’ and ‘refresh’ commands from the hub, but this had no affect. I also tried short & intermediate presses of the device reset button without affect. After this, the device was deleted from the hub, then reset with the 3 second press of the button, and added to the hub again, then reconfigured in the rules in which it participates. After which it continued to work normally throughout the day.
But, again, the next morning, the sensor flashed on motion in the area, but no trigger was logged to the hub. This time, I tried simply removing and replacing the battery, and the sensor began to log events on the hub. Much better (except for having to force the back open), but not something you want to have to do every morning. So, the detector portion seems to stay alive, but, something else within the unit seems to fall into a deep sleep after a longish period of inactivity. At this point, the sensor is in the mount I made for it with the back off for a simple reset, until a different brand replacement can be obtained.
So, unlike my many, rock steady, Sonoff S40ZB Zigbee Smart Plugs, this SNZB-03 Zigbee Motion Sensor is looking like a disaster. However, the sensor has an excellent range and sensitivity with an active/inactive reset timing of ~60 seconds, but getting to the battery is a real pain with very high forces required, and the non-recovery from a longish idle period is not at all good. Also, it only reports motion state to the hub, but battery state is an important and very much needed value. This seems to be a ‘close, but, not quite’ device. I had high hopes for it, but, it looks like, ** instead of ****, and, while I am still trying to find a formula that would make it dependable, it sure looks like I’m,
Works as it's designed to....Not as you would like it too.
I wanted to monitor the temperature in the garage storage closet via Alexa. Here’s what you need to know:
Environment: Samsung Smart Things Hub (the last Samsung version) for the backend and Alexa for the front end. You do not need a Sonoff hub as this Zigbee device is detected by the SmartThings hub when placed in pairing mode. I haven’t bought a Sonoff hub because its doing what I want.
Process: Place it in pairing mode and look through the Rooms in the SmartThings hub. You will find it in an Unassigned Devices area and need to select the Room you want it in. SmartThings is fairly robust with it, giving you Temperature, Humidity, and Power. In settings you can offset the Temperature and/or Humidity if you find the Sonoff reading high or low and have a trusted thermometer/hrydrometer. For Alexa follow the instructions, add the necessary skill, and your good.
Alexa: Alexa will tell you the temperature, if the device happens to be online when you ask. Alexa does not support humidity or power level.
SmartThing: If you check the device here, you will most likely find it offline. This is a zigbee radio device, which means low power and power conservation. If its offline, view the device anyway. It will provide the last environmentals. You can also view a log with several days of readings. This is key. Also, the line of site for my installation is through 3 walls and a refrigerator. I haven’t had to reset it, it just runs.
The SNZB-02: It is designed to transmit temperature and/or humidity when they change. There is some temperature reporting at 2 hour intervals but I have seen no temperature for up to 9 hours in the log and can only assume that there was no change. And this makes sense to get the appropriate mileage out of a CR battery device.
Perception Resolving: since all the data is in the SmartThings hub, Amazon or Sonoff needs to come up with a skill that is hub based, not device based. This skill needs to read the environmentals from the hub, ignoring that the Sonoff is offline, possibly including the date and time when the temperature was last read. The assumption on a lot of buyers that this is an instant reading device would then be mitigated.
Would I buy more? Yes. I have a need for the garage itself and the sunroom, and at this price I’m happy with how this works now that I have critically thought out its processes and limitations.05/08/2022Verified Purchase
Works with an old Echo 2nd gen plus.
I’m totally blind, I got this to put in the stairwell going down to the basement. The sensor is square in shape and has a half dome in the front of it. To me, this sensor looks like they just took the temperature sensor and just added the dome on it for motion detection. The battery replacement is the same. You pop off the back of the sensor to get to the battery.
I connected it up to my old Echo 2nd generation plus. The sensor had no issues connection. My only complaint. with this sensor is the area that it covers on the side is touchy. It is in the stairwell and if I walk by the stairwell I used a routine for Alexa to turn on and off the lights in the stairwell and had it announce a message through the Echo to let me know when the lights got turned on and off. This picks me up just walking along side the stairwell and not even in the stairwell. Now if I could just find a way to cause it to not pick up so much on the side of it! It would be great. Set the Alexa routine to only be active for days I’m likely to have someone go down to the basement. That away the lights aren’t always turning on and off.
No idea of how long the battery will last. It uses a 2450 battery.04/30/2022Verified Purchase
