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
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.

Unreliable and inconsistent
Sadly, just not reliable or accurate motion or presence detection. Sometimes the motion is picked up nearly instantly, other times a minute (if it picks up at all). Sometimes it can indicate clear as a result, even within 5 feet of a target, despite trying with numerous positions and angles. The thermometer updates every 15 minutes, but was the most consistent in its measurements. I find the bright/dark detection too course-grained to be useful unless you are using it to confirm a nearby light is on or a room is receiving sunlight on a cloudless day. Battery lasted 4 months, always reporting around 80%.

Works well, easy connect with HomeKit.

Was eenvoudig te koppelen en je hebt lekker veel knoppen om te programmeren.Helaas was de werking van korte duur. Regelmatig moeten resetten door de batterij de verwijderen om hem weer werkend te krijgen, maar inmiddels werkt dit ook niet meer.Na verwijderen uit homekit, kan bij het opnieuw koppelen de knop niet meer gevonden worden. Oom nog de Onvis app geprobeerd, maar helaas, troep dit
