How does the alarm work within HomeKit?

Connecting to a smart home
The Onvis CS1 alarm with a magnetic sensor paired with your HomeKit hub sends instant push notifications when the sensor is activated. This means that you will immediately know that the door (window) is open. This will easily give you a reliable 24/7 overview of the security of your home, garage, office, or warehouse and effectively deter thieves. The sensor can also be controlled by voice commands via Siri.

Adjustable alarm
You can set the alarm sound in a moment according to your needs in 4 selectable modes, which correspond to different uses. The volume of the burglar alarm is up to 120 decibels with 3 volume levels and an adjustable time delay. You can control the alarm via the application, the button directly on the device, or Siri.

Create useful automations

Switching on the sensor can also serve as part of automation, which will save you energy, make your stay at home more pleasant, or make it easier to manage any interiors. Activating additional HomeKit devices by opening / closing the door, or a specified temperature / humidity will help you improve the care of your wine cellar, animals in pens, warehouse, or office and save your energy costs.

You can install the alarm yourself in a moment

Use the accompanying Onvis Home application or your existing Apple Home application. After you scan the code, the pairing of the device with your HomeKit hub will be complete in a few minutes. The small size of the alarm and battery power allow installation on a variety of surfaces, such as doors, windows, gates, pens, or cabinets.
