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

Review: Fast Reliable Motion Sensor - We have smart switches and lights in our kitchen so we have been looking for a smaller battery powered Matter or HomeKit motion sensor. We wanted some of the lights to turn on and off automatically when you enter or leave the room. I setup the motion detector on a shelf about 20 feet from the entrance to the kitchen and near another hallway that someone might walk in from in the dark. I angled the motion detector so it’s seeing activity also in the kitchen to trigger motion. Works perfectly with the automation I setup to turn on the under-counter lights if anyone enters the kitchen between sunset/sunrise and if the overhead can lights were turned off. I needed to use the convert to shortcut feature to achieve this when creating the automation. Another thing I appreciate about this other than how fast it triggers the lights to turn on/off and its motion detection distance is that it is built on thread so that it isn’t connecting as another device to Wi-Fi but instead connecting through the Apple TV or HomePod Mini we have. Nice that it includes a temperature sensor and humidity sensor which were almost exactly the same readings as my smart thermostat. The Onvis app definitely needs an interface overhaul to update it to iOS design language but it functions well. Really easy to adjust settings within the Onvis app such as the interval that it is checking for motion, motion sensitivity or even if you want it to only detect motion in the light/dark or always. I did run into an issue with Apple Home when setting up an automation saying if the motion detector turns on versus detects motion but I just force quit Onvis and the Apple Home app and restarted creating the automation then it populated the detects motion trigger.
Review: Disabling a motion sensor is finlly possible! - If you use motion sensors to turn on lights, there are times where you want certain lights to not turn on at all. If you are a HomeKit user, the only way to make this happen is to use a Homebridge dummyswitch, which for nontechnical user is a lot to ask. The other option is to use another HomeKit accessory, like a light bulb, as a condition in your automation. While this works, you need to find an unused accessory or buy a new one to use as the on/off switch. Enter the new Onvis SMS2 motion sensor, which gives the user the ability to disable the motion sensor within their app, and in HomeKit. In the app, you can easily disable the motion sensor from the main page. In HomeKit, there is an “Active” flag that can be accessed in various 3rd party HomeKit apps. Further, since this flag is exposed to HomeKit, you can use it in HomeKit Scenes, Automations, and Shortcuts. Now, if you just don’t want the motion sensor to trigger accessories at all, you can create a Scene and then say: “Hey Siri, disable the bedroom sensor” and now that motion sensor will be completely disabled. If you want to disable the motion sensor based on an IOS focus mode, this is also now possible via a Shortcut. The great thing about this solution is the average user can now enable/disable the sensor without any need of additional technical knowledge like Homebridge, programming a Hue Bridge, etc. It just works. When the motion sensor is disabled, then those disabled accessories do not trigger even when you use scenes and automations if those accessories are a part of it. If you have other motion sensors, you can now include this new “Active” flag in their HomeKit automations to disable them as well. This is a problem that has plagued motion sensors since HomeKit gained support for them. We now have the ability to turn off the Onvis motion sensor as easily as turning off a light switch. So, if you have guests over, you can quickly disable all automations until they leave. The other interesting thing about this motion sensor is that the motion sensor timeout is also exposed to HomeKit. Therefore, if you need the motion sensor to have a different timeout depending on certain scenarios, you can do this now. For instance, during the day, the timeout in my bathroom motion sensor is set to 5 minutes. But late at night, it’s set to 1 minute. The motion sensitivity is also exposed to HomeKit. If you find the motion sensor is not triggering as you like, because of the ambient temperature, you can dynamically change the motion sensitivity to compensate. There is also a "Reminder" feature that tells you when the countdown timer gets to a percentage of the total countdown time. For instance, if the countdown timer is set to 10 minutes, you can set the reminder to 50% of that value. Then in the Onvis app, you can create a custom automation to dim the lights when that value is reached. This feature appears to allow the user to simulate the slow dimming feature of the Philips Hue lights when paired with their motion sensor. Lastly, the sensor also includes a temperature and humidity sensor. And finally, these sensors can b calibrated to match the values of other temperature and humidity sensors you may have in the same room. This is another feature that has always been missing from multi-sensor products. The only feature that is really missing from this product is a true light sensor, like Eve Motion and the Hue motion sensor has. Therefore, automations based on lux values are not possible. But with that said, I’m still giving it 5 stars because of the activation/deactivation feature of this motion sensor and being able to change the motion sensor timeout and sensitivity via HomeKit. The activation/deactivation feature alone is saves a lot of time and aggravation. So, even if you have another HomeKit motion sensor, I highly suggest buying this new Onvis motion sensor and use it in conjunction with what you have in order to be able disable automations more easily.

### ⭐⭐⭐⭐ Discrete and affordable, decent performance
*by M***R on April 20, 2021*

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.
