Do you want your light to turn on automatically when you go to the hallway? Just smartly set the scene to activate your home into action.
Connect a camera to the motion sensor and place it almost anywhere in the house, then you can see what is happening in your home through the camera on the sensor page of the APP.
It can provide a detection distance of up to 6M and an angle of up to 110° when the sensor is operating, ensuring that suspicious movement near your home is detected even earlier.
You will receive a low battery notification when the battery life is at 10%.
Simply use the 3M adhesive tapes to place the motion sensor in your ideal locations in seconds.
There are two ways to activate the SNZB-03.
Specifications are collected from official manufacturer websites. Please verify the specifications before proceeding with your final purchase. If you notice any problem you can report it here.
I have a total of 5, no problem with any of the 5. Excellent for their price and for the purpose I bought them (to turn on the lights). They do not work for an alarm because they take time to reset and detect motion again.
The battery drains very quickly and the app does not provide accurate information about its level. Frequent disconnections that turn off the sensor and then to reconnect it, the pairing process had to be repeated several times. It is better to choose a more reliable solution.
I have 4 of them and as long as they work, they are ok BUT they go offline on their own without any other device connected to the sonoff zigbee hub having an issue. Sometimes they get stuck on detecting motion for hours when there is none. You have to reset them to get them back and re-register them in the routines. I do not recommend them.
They were purchased for automation through home assistant. They were connected to a ZigBee tuya hub, with which the sensor never sent motion cleared, resulting in it not being usable. Later, I read many reports on the internet from users with similar problems. Before throwing it away, I decided to try the native integration of home assistant by purchasing a sonoff USB dongle p (plus). It connected immediately and has been working perfectly since then! If you are indeed experiencing issues with this specific sensor, it may be a problem with the ZigBee hub.
I have 5 of them that work with smartthings without any problem.
The only drawback is that you cannot set a reset time.
With the instructions provided by user roa below, the device works perfectly. I have connected it to Home Assistant through SONOFF ZIGBEE BRIDGE. Perhaps the disconnections are due to the channel of your WiFi. Try changing the channel
Described in one word: 'Garbage'. Stay away. I bought two, over 1+ month ago. They are the worst devices I have ever used. They do not have the range they claim in any case whatsoever. Even in the same room, without obstacles, outdoors (without other networks), both devices are out of network most of the day, at a distance of 1-2 meters from the zigbee coordinator. Out of the 34 zigbee devices, these are the only devices that behave like this. The 'you get what you pay for' principle would indeed apply here if zigbee devices were not already excessively overpriced compared to competing technologies.
You get what you pay for. Excellent product for its price. I have it as a sensor to turn on the lights in the room, and it's okay. From the moment it detects motion, it takes 2 minutes to send another motion detection. So if something passes in front of it, you will receive a notification, but if something passes again within the next 2 minutes, you won't receive one.
Give some extra money to get something more reliable. Constant disconnections, freezes on motion detected, battery runs out quickly. If you're going to deal with the basics for so long, find something else and use your time more creatively. (I've bought 3, all dysfunctional)
The sensor works correctly but with specific rules. That's why some people may be disappointed.
I have 5 of them connected to a Sonoff ZB Bridge-P and they all work as expected.
After some experimentation, I came up with the following 5 rules:
1. When the sensor detects motion, it sends a "motion detected" signal and instantly lights up a red light on the sensor.
2. As long as the motion remains, the sensor "sees" it but, be careful, it does not send a new signal. Even if the motion continues for hours, the sensor will "see" it but will not send a new signal.
(This is very convenient for me because I installed a sensor to turn on the kitchen countertop lights. As long as there is motion in the kitchen, the lights stay on.)
3. If the motion stops but returns within less than 1 minute (e.g. I leave the kitchen and return after 50 seconds), then the sensor remains in the initial "motion detected" state and does not send a new signal.
4. If the motion stops or if the sensor does not detect it for 1 minute, then it sends a "no motion detected" signal and instantly lights up a red light on the sensor. As long as it does not "see" motion, be careful, it does not send a new signal.
5. From the moment it sends a "no motion detected" signal until it can detect motion again, be careful, approximately 5 seconds must pass. Once it detects motion, we return to rule 1.
The problems start if we use a "delay" function.
I'll give an example where the sensor will work correctly but it will appear as if it is not working correctly.
We set up a sensor to turn on the kitchen lights and create a routine "scene" where we add a 5-minute delay and then the lights turn off.
We enter the kitchen and the lights turn on normally.
However, as soon as the 5 minutes pass, the lights will turn off even if we are still in the kitchen.
This happens because the sensor has "locked" in the "motion detected" state and does not send a new signal (rule 2). But the routine is running and does not refresh as long as someone is in the kitchen, so as soon as the 5 minutes pass, the lights will turn off. And if they turn off, no matter how much motion we make, they will not turn on and it seems like the sensor is not responding. However, it is functioning correctly according to rule 2.
Therefore, it is advisable to avoid using "delay" functions.
For indoor use, it is very good, it has excellent connectivity with Alexa. And you can create routines - scenarios through the ewelink app or Alexa. The connection with Google was not as good
At least 2 out of the 3 give false alarms, now I will try the third one, but I already know the result.
Also, I have the large PIRs from Sonoff, one indoor and one outdoor, they do not give false alarms (fortunately).
I don't know why some people have complaints. I installed it above the external door with a routine through Alexa when it gets dark and detects motion, it turns on a floor lamp in the hallway for 1 minute so I can enter the house. Everything I have bought from SONOFF and I have bought many things, all work flawlessly.
It is not worth it for outdoor use, every now and then it makes a lot of noise and scares away all the birds, while there are some sparrows on the balcony. Only at night it is a bit quiet haha because it doesn't have bats. It is exactly the same as the other one which is not pet-friendly and both of them make noise at the same time from something in the outdoor area.
Not very reliable with the Sonoff Zigbee Bridge. However, by changing the firmware to Tasmota (zigbee bridge), no problem
It is good for running simple routines with Alexa in a smart home. Not suitable for security sensors for alarm systems. After detecting motion, it goes into sleep mode for 1-2 minutes. It experiences some disconnections.
It does not work properly, it takes false motion commands and drains the battery quickly!!! I do not recommend it, I have already bought 4 and they all have the same problems
I will not say that I am thrilled by its sensitivity!
It is well constructed and easily connectable through the Sonoff application.
It connects instantly with Amazon Alexa
Verified purchase
VERY short battery life (2 weeks) in a place with daily movement inside the house (kitchen).
Verified purchase
They work very well, I didn't have any issue
Verified purchase
Very good, but within 2 months it ran out of battery!
Verified purchase
Good for the money it costs!!
It loses connection when I change between the two that I bought
Verified purchase
It constantly sticks and the battery runs out quickly
Verified purchase
If it doesn't catch movement for a few days, it disconnects on its own.
