Works worldwide. SMS/call delivery and pricing varies by destination country and uses your portal balance.
How a power cut alert SMS works
A power cut alert SMS system monitors a location and sends you a text message when mains electricity fails. It’s useful when you’re away from home, managing a remote property, or protecting equipment that must stay powered.
PowerNotify uses a small USB device connected to Wi-Fi. While power is present, it checks in with the cloud. If power goes out, the device loses power, the heartbeat stops, and after your chosen delay PowerNotify sends alerts — including an SMS to your selected phone numbers.
Why SMS is useful for power cut alerts
- SMS is easy to notice quickly when you’re out.
- You can add multiple recipients (family, neighbours, staff).
- Ideal for fridges/freezers, aquariums, CCTV, comms racks and remote sites.
What triggers the SMS power cut alert?
A power cut alert is triggered when the device stops checking in for longer than your configured alert delay. The most common cause is a mains power cut (because the USB power source drops), but it can also happen if the local Wi-Fi or internet connection fails.
To reduce false alarms, most people set an alert delay of around 60–180 seconds. This filters out brief Wi-Fi drops, router reboots, or momentary interruptions.
Tip: use SMS + email together
Many customers enable email alerts (free) for a detailed record, and SMS alerts for the fastest “heads up”. If you’re protecting something critical, you can also add phone call alerts as a final escalation.
Where SMS power cut alerts are most popular
If you’re protecting anything that can be damaged by an outage, SMS alerts can give you time to act.
