Today's the day, boys and girls. It only took Nintendo nearly 3 years to make it happen, but it's here! The Home button on your Joy-Con and Switch Pro Controller will now light up blue, thanks to the Switch firmware update 9.0.0. This is because of the new 'Alarm Notifications" feature that was part of the update.
Alarm Notifications have been added to System Settings > Notifications.
- You can check or delete pre-set alarms.
- Alarms can be set up only within supported software (to be added at a later time).
- A controller firmware update may be required to use this feature.
You might need to do the separate Joy-Con/Pro Controller update in order to get this feature to work, but the end result will be a lovely blue light for your alarms!
