Activate and deactivate the alarm at the press of a button. 

You come home late at night in the dark and want to get into the house quickly - if only it weren't for the alarm mode being activated. No problem with Homematic IP: With the key ring remote control, you can activate and deactivate both alarm functions from inside the car. The button is located within easy reach on the key ring so that you'll press it quickly and instinctively. The alarm mode can also be reliably deactivated with the remote control switches and works, even if the Internet is down.
