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: Reliable and easy to setup - I purchased the "Onvis Smart Motion Sensor, Wireless Hygrometer, Thermometer" smart sensor to replace some old analog temperature and humidity sensors in our Apple HomeKit system. It installed without issue in 1-2 minutes. It's been running for a month and I haven't noticed any connectivity issues. I haven't had to perform any resets or re-pairings. It seems to work pretty reliably with our Unifi wireless network. The motion sensor is reliable and triggers the automation attached to it every time we walk by. The temperature and humidity sensors consistently report a temperature that is 1-2 degrees higher and a humidify that is 1-2% higher than the old analog sensors and the sensors attached to our furnace controls. That's close enough for my use. If you require exact temperatures you are going to want to do some testing with this sensor. Overall, I'm happy with this sensor and will likely buy more when/if they go on sale.

### ⭐⭐⭐⭐ Easy! Works like it should
*by J***Y on 24 June 2026*

Super easy to pair up with Apple Homekit, as well as the Onvis app. I bought this to measure temp and humidity in my basement, so I'm not using the motion sensor presently. The only thing I don't like is that Homekit will not allow me to set a notification to my iphone if the humidity reaches a certain level....I think this is an issue with Homekit rather than the device, as I have the same issue with a door contact sensor from another brand.
