Smart Motion Sensor, Wireless Hygrometer, Thermometer, Works with Apple HomeKit, Smart Home Automation, PIR Motion Detector-Thread ((iOS 17.4 and Above is Required)

I have 4 of these. One purchased in May 2023 and it's been great cost effective sensors.I love the direct integration with Apple Home (with supported Apple Hub device). This particular version/item was cheaper and had statements which referenced requiring Onvis Thread Bridge/Gateway (which I don't have), so wasn't sure if it would work.The item description/formatting should have -or- inbetween all the options. I'm writing this post to let others know that this particular listing works with Apple Homekit w/o the need for their bridge/gateway.

Edit, longer term review. I just recently bought my second of these. I have been very impressed with the first one I bought a year ago. I've been amazed how long the batteries have lasted. I have the original batteries in the first one I bought and they're still going strong a year later. That's really impressive given this sensor is constantly monitoring motion, temperature and humidity.Since I wrote the review below I have also started to use the humidity sensor to turn on and off my dehumidifier when it goes above or below a set level. It works great and keeps the humidity in the range that I like. I do still also use it to turn on lights at night so I never have to walk in the dark. I pair it with vocolink lights so I can have them turn on at 20% when the Onvis detects motion.Very happy with how they work, super impressed by the battery life, and overall great quality.--All I really wanted was a motion detector that would turn on the bathroom light when I get up at night. It works great for that. I had it up and running in Home in just a few minutes. I set up an automation to trigger the bathroom light (and turn it off in 4 minutes) between midnight and 5 am and I'm all set.Worked perfectly. As I think about it I can think of all kinds of uses for motion detectors like this but for now it's basically my automatic nightlight.

So the good: they are small, easy to setup, and connect into Homekit super reliably.I never had one fail on my adding to Homekit. I have had no problem adding it to Homepass as well, where I archive everything. They are super easy to program.Their range is decent. The normal placement of a motion sensor, up high, seems to really limit the range. If you put them at body height they work well. In my larger rooms I include multiple sensors for coverage (turn on when ANY trigger, turn off when AND turn off AND all of them are off).I've bought about 25 of them, scattered around the house. The inclusion of humidity and temperature sensors is pretty neat, though I'm not sure how much that helps.I have some Eve Sensors for outdoors, they work about the same, and are twice the price, and don't come with the extra sensors. Eve also uses a strange battery size, while Onvis is AAA, available anywhere cheaply.The negatives: like most Homekit devices, they have their own app that you need to install to manage the firmware. Like the apps from every company but Eve, the app is utterly awful. Since you only use it to upgrade firmware, this isn't too big a deal. However, it doesn't have a good way to see which ones need upgrading, so expect pen & paper while you upgrade.The sticky pad - it's cheap and mediocre. Maybe if you alcohol and dry the wall you can get it to work. For ones I want removable, I bought 3M Command Medium, and those generally work fine... walls with heavy knockdown or texture may not.It includes two anchors and screws, I highly recommend using those if you are installing over tile. I managed to break the back cover off mine. The company shipped me replacements for free, but I had to pay shipping from China and wait.All in all: it's a great device at the price. Most of the limitations are livable. They are cheap enough you can fill your house with them, which is why I recommend them. All the downsides are inconveniences, and the upsides are a functional, discrete, affordable, reliable solution.If you can deal with installing drywall anchors or buying better sticky tape, and taking the time to upgrade firmware, you have a solution.
