Frequently Asked Questions

The app lets you control select Airscape fans using your iPhone. The initial version of the app is ad-free and offered at no charge. Version 2 will add an optional paid feature to pre-cool your home.

All versions are ad-free.

With the Porchdog app for Airscape whole-house fans, you can wirelessly control your whole-house fan from anywhere in your home.

The app downloads current outdoor temperatures from the service and can notify you when the outside temperature is too hot or cold for optimal whole-house fan use.

Some Airscape fans have a speed control feature - also known as an "interlock" - that can automatically slow or stop the fan. These interlocks can lower fan speeds when not enough windows are open or if a smoke alarm is active. If your installation includes these options, the app will notify you whenever the fan's speed has been automatically reduced.

If your fan installation includes optional temperature features from Airscape, the app will use temperatures provided by those modules.

If an Airscape temperature module isn't installed, the fan will contact to get the current outdoor temperature for your location.

If you decide to provide your GPS coordinates, be sure to set up the app while you're near the fan. Otherwise your temperature readings will not be accurate. Once you've provided your GPS coordinates the app will store them for future use.

The app will not display the indoor temperature unless you have Airscape’s optional indoor temperature module.

As a general philosophy for both the site and the app, we do not collect personal information of any kind, except as needed for participation in Apple's app store, to provide product support (e.g. troubleshooting), or to deliver the app features you choose to use.

Take, for example, our use of your location information. If you choose to let the app find your local outdoor temperature, your location will be sent to Besides the networking information required to contact the service, the only information sent to are your GPS coordinates (based on your settings). Porchdog Software does not receive or have access to your location information.

The app can scan your network for all Airscape fans on your network. Model-specific capabilities (like the number of available speed settings) are configured automatically. When you first open the app, you'll want to go to the "Network" tab to find and select your fan.

Your fan's IP address may change from time to time (power interruptions, for example, may restart your network and cause address changes). If you experience a "fan not found" error, please go back to the Network tab and re-scan.

If you have more than one fan at home, the app will find all of them. Although the app can only control one fan at a time, you can switch between fans on the "Network" tab.

We worked hard to get all the kinks out of our whole-house fan app. But if something's not working, please let us know. Report all issues using the “Feedback" link.

Please note that we are not affiliated in any way with Airscape Fans. We are very happy fan owners but we'd be way out of our league trying to support their fine products!

Gen 2 controls are required to use the app. Airscape recently discontinued support for gen 2 controls on new fans, but many installed fans support it. If you don’t know if your fan has these controls, download the free app and scan for a fan on the “Network” tab. If there’s a compatible fan on your network, it’ll show up in the list.
