What if I’m seeing an ‘Unexpected Error’ message during the Accessory Setup using an iOS smart device?
An "Unexpected Error Occurred" indicates one or more of the connection / registration steps failed. Please verify the following:
- You are connected to your home Wi-Fi on your mobile device and airplane mode is on (not using mobile data).
- You are within 5-10 feet of the thermostat throughout the connection process.
- Your mobile device has the most recent version of the Honeywell Home mobile app, and is running the latest OS/iOS version.
Once these steps are completed, force close and reopen the Honeywell Home app and try again.
