Onvis Door Window Contact Sensor, Magnetic Home Security System, Works with HomeKit, Automatic Notifications, Remote Access, Bluetooth Wireless Low Energy Battery Powered, No Hub Required (1 PACK)

After a few days i've decided to update my review. So it seems the device takes a little time to start up (an entire day to be specific) but after the first day it seems to work every time with no fail. Just beware that it may take some time to start up but after the first day it works flawlessly. Couldn't be happier.

Previously used Eve's version but the Onvis Door Sensor is just as good - uses a button cell battery which is easy to replace.Can be set-up entirely inside the Apple Home app but the Onvis app gives you detailed logs and allows for Firmware updates.

Small form factor sensor provides many mounting options, and was easy to pair with Homekit hub (needs to be within Bluetooth radius--2 walls and 20 feet for me). Now I get notifications on my iPhone when side door opens and closes, with no false or missed indications.

Super Produkt!Gut verpackt und wie angegeben 2 Tage später im Briefkasten gewesen.Die Installation war sehr einfach und unproblematisch bei der Installierung mit meinem  kit. Ich habe es mehrmals an Tür und Fenster ausprobiert und bin sehr zufrieden. Ein Pluspunkt ist vor allem das schlichte Design!Die Anleitung ist leicht verständlich. :)Ich kann es nur weiterempfehlen und würde es jederzeit wieder kaufen.

There isn't much to say... Setup was accomplished completely within the Home app and the sensor is very quick to report status changes. Instructions are very succinct - far too brief in my opinion as there are virtually no instructions included so users will need a basic familiarity with what they are doing. Still, for a simple sensor that is so quick to report status and requires no hub, along with its remarkably small footprint (about the size of a Tic Tac box) I cannot recommend this product enough. I plan on watching for price drops to outfit all of my exterior doors.

Homekit va benissimo. Unica pecca è che funziona solo con il bluetooth. Se lo dovete installare in un garage dove portate internet con un powerline, appena andate via dal garage non funziona più perchè perde il segnale del cellulare.

Habe den Kontakt bestellt um über Home Kid die Heizung auszuschalten wenn jemand das Fenster im Bad Öffnet. Hat alles super geklappt das einzubinden. Das Produkt ist klein und gut Verarbeitet. Und für den Preis super es in HOME KID einzubinden.
