Custom Sounds and Critical Notifications
It is possible to customize sounds for notifications coming from Blynk. There are three main push notification channels:
In-app push notifications from a device triggered by events configured in the Blynk.Console
Notifications triggered by Automations
General/other such as content events notifications or Rule engine notifications (business plan only)
Each channel can be configured to turn on/off all notifications or use custom sounds, and device event notifications can be configured as critical alerts in some cases.
Device Event Notifications
For a notification to be considered an alert and become eligible for sound customization, a corresponding setting must be turned on in the Notifications tab of the event settings on the Blynk.Console. Go to Templates -> Template -> Edit -> Events Tab, select an event, and then the ‘Notifications’ tab. Enable the option ‘Deliver push notifications as alerts’ and then configure the sound settings in Blynk apps.
On the ‘General’ tab, enable the option ‘Send event to Notifications tab’ if you want the event to be visible in the app notifications tab.
For iOS:
Go to Main menu -> Settings -> Notifications and sounds -> Devices. From this menu, you can enable/disable notifications from device events or select a custom sound for it.
For Android:
Access notifications by choosing Profile -> Settings -> Notifications and sounds -> CRITICAL NOTIFICATIONS. From here you may turn on/off Critical Notifications, and when enabled, choose the notification sound.
Critical notifications
iOS
Clients using BUSINESS plan can cause critical alerts to be recognized by iOS, resulting in delivery with maximum sound, ignoring the phone’s mute and Do Not Disturb settings.
Approval for the app to use this feature is required by Apple.
Android
On Android, Critical notifications were created to bypass the Android app Do Not Disturb setting and to enable custom sounds for different triggers. (By default when Do Not Disturb is enabled for Android, notifications and sounds are suppressed).
If ‘Ignore Background Restrictions’ setting is on, Blynk will run in the background and will try to push notifications despite the phone’s do not disturb settings.
For some device models Android ‘Do Not Disturb’ may still prevent receipt of notifications.
Notifications customization by device
On Android, notification settings may also be configured for each Blynk device. Select a device, and then tap on the More info icon, tap on the More info icon again, then within the ‘Actions’ page, select ‘Notification Settings’. From here you have extensive control over the notification settings for the device, including the notification sound.
An additional setting ‘Override Do Not Disturb’ can be found by expanding the ‘Advanced’ menu. After enabling this setting, a window will appear asking for permission to always run the app in the background.
Customize Notifications from Automations
The detailed notification setting options for each automation are accessible from the Blynk.App and vary depending on the platform.
For iOS:
Go to Main menu -> Settings -> Notifications and sounds -> Automations. From this menu, you can enable/disable notifications from Automations or select a custom sound for it.
For Android:
Go to the Automations tab, select automation, and then choose ‘Notification Settings’.
