SONOFFSNZB-06P Zigbee Human Presence Sensor, Zigbee Smart Motion Detector with 5.8GHZ cmWave Radar, Requires ZigBee Bridge (1)

This is a very basic radar presence detector. It was immediately discovered and configured by Home Assistant. I have been using it for my office lights and it is very responsive. It features 3 levels of detection that you can set with the button. It is about 1.25 inches in diameter and uses a magnet in the base to allow you to position it easily. I plugged it in with a old phone charger to keep it powered. There are more options that allow more programming capabilities but this is easy and a good way to test presence detection easily.

I set this up with Home Assistant and zigbee2mqtt to control two Zigbee-based outlet switches for my office lamps. It works exceptionally well. You can even set a threshold in the device to determine how long it remains active between detections, which is a useful feature. The integration with zigbee2mqtt is seamless and exactly as expected—this is actually a significant advantage that may not be immediately obvious. It also works flawlessly with Home Assistant Automations.The only reason I’m not giving it 5 stars is that it occasionally experiences interference from my 5 GHz Wi-Fi network. This is likely partially my fault, as my high-powered Ubiquiti AP is located just 3 feet above the device. I suspect it uses the 6 GHz band for its radar functions, which might be close enough in frequency to the 5 GHz Wi-Fi signals to cause interference.Overall, it’s a reliable and well-designed product that meets my needs, with only minor drawbacks that are likely due to environmental factors.

I tried the SONOFF SNZB-06P using the SONOFF Zigbee Bridge Ultra - Matter Compatible Smart Hub with Matter connection to Homey Pro. Everything connected flawlessly, no problems there. Except that the sensor itself is flawed and constantly indicates presence. No matter what I tweak in the eWelink app it won't work. Sonoff REALLY needs to fix this POS device. They don't seem to be concerned that they are taking people's money as there hasn't been a firmware update in ages. I don't recommend this sensor. If you want a much better device buy the Aqara FP1E presence sensor. The SNZB-06P was half the price of the FP1E but I guess you get what you pay for.Edit: I increased my review by 2 stars. After working with the sensor for a while I discovered that the magnetic metal base really interfered with the signal. So, I removed the base and just used command strips to hold it in place (you can use anything nonmetal you want). The sensor started working well! The only downside is it's a little slow on sensing presence and the sensitivity/distance can't be adjusted. But, it functions as expected now. I placed it next to the Aqara motion sensor for comparison, and it functions now.

I REALLY wanted this to work, I've had awesome experience with Sonoff's smart fan/light relays, but it just wasn't so. Maybe it was just released too soon and will likely be fixed with a driver update but as of this moment, it's pretty useless. Biggest problem is in it not flipping back to motion not detected after detecting motion. Even with the lowest sensitivity. I tried reinstalling the driver multiple times but didn't seem to help any. The information and user guides were quite confusing leaving me with many questions. There is a sensitivity setting in the app, but I believe the button on the side of the device adjust the sensitivity as well, but they don't seem to match or affect each other. Also, and I know this is petty but it's really poor design to put a status light on a button that you have to press. (Your finger covers the light.) I know eventually they will get the kinks out and it will be a nice unit but it's just too soon.

I used the SONOFF SNZB-06P with Home Assistant. The Zigbee connection was solid and paired easily, but the sensor kept getting stuck in a constant “detected” state even when the room was empty. It took a lot of tweaking and trial-and-error to get it working reliably. Once it stabilized, it was usable for basic presence detection, but the initial behavior was frustrating. Decent hardware, but the firmware or sensitivity needs improvement.

I would give this device a solid "Good Enough". It's getting the job done and I'm overall satisfied.I'm using this with Home Assistant and Zigbee2Mqtt. No issues there. All the functionality is fully supported. Response time is quick.One important thing to note is that unlike some other mmwave devices, this one will not tell you distance or size or number of objects. It's really just a binary presence sensor. It's pretty good at that, but if you need fall detection you will not get it here. You can adjust the sensitivity, but it's just 3 different levels (low, medium, high).I have a few complaints, but none of them deal breakers. At first I thought the magnetic mount was a great idea. In theory it allows you to point it in any direction and it seems to hold pretty strong. But once you plug in the power cable it pulls the device in different directions and limits the full range of motion. I ended up squeezing the device into a little gap on a shelf so it would stay pointed the direction I want.I had trouble with some of the locations I tried. One thing I really wanted to try was putting it under my desk pointed toward my chair so I could avoid any detection from the rest of the room. I was getting a ton of false positives though. I'm not sure if it was electrical interference or what. Moving it away from the desk has made it much more reliable.

Lost connection to zigbee hub MULITPLE times. Using through home assistant, and it worked perfectly the first week or two, and then it started dropping .. OFTEN. I need a presence sensor but unsure what to get now. Went back to standard motion sensor for now
