Power outage alert: know when the power goes off — even when you’re away
PowerNotify is a compact power outage alert device that monitors a location and notifies you when mains power fails. Choose email alerts (free), SMS, or phone calls depending on how urgent your setup is.
Works worldwide. SMS/phone calls use your portal balance and vary by destination.
Common reasons people want outage alerts
- Food spoilage risk in fridges and freezers
- Aquariums and reptile enclosures relying on heat/filtration
- CCTV and security systems going offline
- Remote sites, comms cabinets and network equipment
- Rental properties and holiday homes
Set a short alert delay (for example 60–180 seconds) to filter out brief Wi-Fi drops and router restarts.
How PowerNotify detects a power outage
1) Heartbeat monitoring
While powered, the device checks in regularly with the PowerNotify cloud. This creates a “heartbeat”.
2) Outage detection
If mains power fails, the device loses USB power and stops checking in. After your configured delay, an outage alert is sent.
3) Restore confirmation
When power returns and the device reconnects, you receive a restore notification so you know it’s back online.
Choosing the right alert channel
Most people enable email plus SMS. For high-value stock or critical systems, add a phone call as a final escalation.
