What is geofencing?


Let's begin by explaining what a geofence is. A geofence is an invisible boundary, a virtual perimeter for a real-world geographic area. For example, with geofencing you can create "triggers" so that when a device enters or leaves the pre-defined boundaries, a device turns on. This way a nicely lit house awaits you when you come back from work.

Here's typical scenario:
When all family members and their phones have traveled out of the designated geofence area (your home), the geofence can set the alarm, adjust the thermostat, turn off all the lights and unnecessary appliances, even lower the blinds. When any family member returns, the reverse can happen: lights on, heat or AC back to the comfort setting, outside lamps on. So that your family members can come and go at will, the smart home will take care of the rest with geofencing.

  4. You can also adjust an accessory by pressing and holding on it.

  5. Tap Done to create the automation. Here you can also test it and specify when to turn it off.

Congratulations, you have just created a geofencing automation! 🎉

Geofencing for Amazon Alexa & Loxone/KNX users

What you need:

How to create Geofencing automations with the Amazon Alexa app:

  1. Add a new routine, hit the + button in the top-right corner.

  2. When you select "when this happens" you’ll see five options, pick Location and follow the onboarding.

  3. Then select a trigger of your choice by tapping the “Add action” button.

Thanks to an update from Amazon, Alexa devices can perform time- and location-based reminders as well. If you set up a reminder based on location (e.g. "Alexa, remind me to take out the trash when I get home”), Alexa will provide it to you on cue. If you're not near an Alexa device, you'll get a push notification through the Alexa app.


Geofencing for Google Home & Loxone/KNX users

Google hasn't introduced geofencing yet, however in November 2020 they've presented the Home & Away routines which trigger devices based on presence sensing.
