The Avia Secure intelligent sash fastener Designed especially for sash windows. Now you can tell at a glance of your phone whether your window is open or closed. Simple to set up and sends alerts to your iOS devices. All Avia devices can be used with Apple Home Automation.

So, what does it all mean?

Apple Homekit allows you to control your smart home from your Apple devices. The Avia Sash Window Fastener will appear in your Apple Home app, and you can view, manage and control this device from your iPhone, iPad, Mac, Apple Watch, or HomePod. Please note – Some features of Avia products aren’t available within the Apple Home app.

The Avia iOS app is available on the Apple App Store. The iOS app will allow you to control all of your Avia Smart home products from your Apple devices, for example, your iPhone and your Apple Watch.


When we set out to develop the Avia range of smart products, home security was a driving principle. That’s why every one of the Avia device family went through a process of design review. We already knew how to develop hardware, but how could we marry that with the latest tech to produce something that not only made life a little easier, it added benefit by improving home security. We think we achieved our goal.
