Using AutoWake with HomeKit

Update - iOS 15.5 Fix

(17 May 2022)

Apple have just released the update to iOS 15.5 and WatchOS 8.6 that will fix the complication issue.

Please be sure to reboot both devices after you update by following the below steps:

Power both devices off and back on again.

i.e. Shut down completely and restart.



Important - iOS 15.4 Issue

Apple has introduced a bug in iOS 15.4 that prevents an iOS app from knowing which complications are active.

Our support team have filed a Feedback report with Apple and personally contacted someone in the WatchOS team to make them aware of it. Until this bug gets fixed, it means that any Watch app that uses this function (like AutoWake) will be unable to work. AutoSleep and HeartWatch are unaffected.

Hopefully it will be fixed shortly. We have noted that the iOS 15.4.1 and 15.5 release did not contain the fix from Apple.


You can use AutoWake with Apple HomeKit to automatically run scenes on key events.

To activate HomeKit support, use the HomeKit switch on the Watch app. This will also let you turn HomeKit on or off at any time.

You then use the Home app on your iPhone to create up to four scenes that are run on key events. Each of these have a standard name. Namely, "AutoWake On", "AutoWake Off", "AutoWake Snooze" and "AutoWake Stop". You only need to create the scenes that you want to use.

Here's how to create scenes in the Home app.

AutoWake On

This scene is run when you turn on the alarm at night. For example, you can use this turn off your bedside light.

AutoWake Off

The scene is run when you cancel the alarm using the main switch. You may want to use this turn the bedside light back on with a dim setting.

AutoWake Snooze

When the alarm sounds in the morning and you choose the optional Snooze button in the Watch app, the "AutoWake Snooze" scene will be run. This is a nice way to turn on a light to cure you of your snoozing ways.

AutoWake Stop

When the alarm sounds in the morning and you press the Stop button in the Watch app, the "AutoWake Stop" scene will be run. For example, you may want to turn on your bedside light to full brightness and start your coffee machine.
