HyperVisu can alert phones and tablets even when the app is closed. The server sends push notifications through the HyperVisu notification service to every device where a user is signed in to the app with notifications enabled.
What sends a notification
- Per-object notification rules. On any communication object you can define a rule — notify when the value is equal to, above or below a threshold, with a repeat interval so you are not flooded (see “Object Settings, Logging & Notifications”). Example: "warn me when the freezer temperature rises above −15 °C".
- Automation notification actions. Any automation can include a push-notification action with your own message (see “Automations”).
- Videophone rings. When the door station calls its ring webhook (see “Cameras & Videophone Setup”), a bell press triggers an immediate notification, regardless of notification rules, so the ring reaches phones that are not running the app. A station without a ring webhook (a Dahua VTO cannot call one) rings only the apps that are running (see “Notifications & Videophone”).
Per-user control
Each user chooses whether to receive notifications in the app under Settings → Notifications (see “App Settings & Personalization”). A user who turns notifications off stops receiving object-rule and automation notifications on their devices.
📘 Note: A device only receives notifications after the user has signed in to the HyperVisu app on it at least once.
