Onvis HomeKit Contact Sensor

by HomeKit Australia


Introducing our super-simple HomeKit contact sensor.

The Onvis CT2 contact sensor is just that - it is a simple contact sensor to trigger notifications or actions within your Apple HomeKit setup.

This Apple HomeKit contact sensor is 100% compatible with Apple's HomeKit ecosystem. You can build endless automations for your smart home and control other HomeKit enabled devices. You might for example open your front door and the entrance and nearby HomeKit lights will turn on automatically.

You do not require a special hub and you can check motion detection records, trigger HomeKit enabled lamp, plug, camera, whatever plus you can use Siri voice control.

In the Apple Home app, you can choose to have the Onvis contact sensor detection send instant notifications to your iPhone, Macintosh, iPad or Apple Watch .... whenever there is an on/off status change. So, put simply, the Onvis sensor tells you whether the door is open or closed offering true round the clock remote home security for your home, office, hotel room, kitchen cupboards, garage, warehouse - whatever opens and closes.

And like all good HomeKit devices this contact sensor is operational in seconds and the HomeKit end to end encryption secures your data in iCloud and iOS devices

As a bonus the Onvis contact sensor stores detection records for 30 days and of course as soon as the contact sensor is triggerred, you receive instant notifications wherever you are in the world.

Three extra spacers are supplied in the package. These are for a door or window where the door jamb and the door don’t fully align, allowing the magnet to be raised up to match up with the sensor.

HomeKit Australia is the sole and exclusive supplier of Onvis HomeKit products in Australia, including the Onvis HomeKit camera with Apple secure video.
