This one is excellent
I bought the same one month ago and I had to return because motion detection was very bad. This one is excellent: quick detection and good range, Temperature and humidity values are very accurate. I already had one previous version SMSK-1 since 2019 and it still works good even in winter at -20c. I think this new one received today has been improved via firmware update.

Not as reliable as Eve, but it’s cheaper
I use both Onvis and the Eve motion sensors with Apple HomeKit to control lights. The Onvis works reasonably well when the signal is decent (ie not too far away from the hub), whereas the Eve, being Thread based, seems to be more reliable. When I say reliable, I mean the response time between motion being detected and the output automation. In my case, the motion sensors were set to turn on my stair lights so I don’t fall in the dark at night, so response time and reliability were important factors. Initially the Onvis worked fine, but over time I found there was an increasing delay between motion being sensed and the output/lights turning on. I found the Onvis battery life did not last as long either. Still, it’s not too bad, installation and connectivity was easy, but after about a year I decided to stop using it whereas the Eve is still working fine.

Works, but detects motion when there is none.
It works well but it constantly detecting motion when there’s no on around, even at the lowest setting. It connected to HomeKit easy, and so far has had a rock solid connection.

Works for short distances
The sensor was purchased to detect motion in the garage, including people and when the garage door opens / closes. At first I tested it at the back wall of the garage, 25 feet from the garage door and next to the door into the house. It detected a person coming out (about 3 feet away) but not the garage door. I found it had to be within about 3 feet of the garage door, so mounted it on the header above the door. That works well. It’s connected to Apple HomeKit. I changed the garage switch to a HomeKit compatible one, and now the garage lights come on when the garage door goes up, not just the light on the garage door opener. The video shows the smart switch for the garage lights, then shows where I mounted the sensor and how close you need to be to it for it to detect motion. It’s easy to tie the motion sensor to a smart switch in HomeKit.

App sucks without notification
The sensor itself is fine, I like the bluetooth connection and thus long battery life. But the app sucks withou any notification from Onvis app or Apple Home app. You can see motioned triggered in the app interface, but nothing else. What a dumb, you can do better without much more effect on the user app. Have to return it.
