Alarms on your HomePod can also be created, deleted, managed and edited in the Home app.
Step #1. Open the Home app on your iPhone, iPad or iPod touch with iOS 11.2.5 or later.
Step #2. Long-tap or press with 3D Touch your HomePod in the Home or Rooms tab.
Step #3. Tap Alarms in the lower-left corner.
Step #4. Tap Edit in the upper-left corner.

Sadly, you cannot pick a custom sound to play when the alarm goes off like on iOS.
Step #6. Tap Save to keep the changes.
Step #7. Tap Done to exit the editing mode.
Step #8. Tap Done to dismiss the Alarm screen.
You can delete any alarm via the Home app in three different ways:
Swipe left over an alarm, then tap Delete.
Tap Edit and tap “-” next to the alarm you wish to delete, then tap Delete.
Tap Edit, tap the alarm and finally tap Delete Alarm at the bottom.
To set a custom alarm clock or a reoccurring alarm, use standard Siri voice commands, wording, relative times and phrases like you would on your iPhone, Mac or Apple Watch.
Here are some examples of using absolute and relative times to set an alarm.
Before you retire for the evening, ask Siri to wake you up in the morning.
You can add context to your alarms by tweaking voice commands with reminder-like language, such as in the half a dozen examples included below.
An alarm created on your HomePod, be it active or inactive, can be easily adjusted in case you accidentally set it to go off at the wrong time or Siri misheard you.
This works best if you name your alarms as described in the previous section.
You can ask Siri to read either all your current alarms or just a particular alarm.
“Hey Siri, delete my feed the cat alarm.”
“Hey Siri, delete my 10am alarm.”
