Power Outage Alert for Fridges & Freezers
Avoid spoiled food and costly stock losses. PowerNotify is a compact USB device that notifies you by email, SMS, or phone call the moment mains power fails.
Why It Matters
A power cut quickly raises temperatures inside domestic fridges, commercial chillers, and freezers. In a busy kitchen or shop you may not notice until hours later — when food safety is already compromised and stock has to be thrown away.
- Instant alerts for power failures (email, SMS, or call)
- Works with any fridge, freezer, or cold room — just use any USB power source
- Simple setup via Wi-Fi and the PowerNotify cloud portal
- Multiple recipients supported (e.g., owner, manager, on-call staff)
What Happens in a Power Cut?
Fridge and freezer units are well insulated, but they are not designed to sit without power for long periods — especially when frequently opened or in warm environments. In domestic settings that can mean wasted weekly shopping; for food businesses, it can mean hundreds or thousands of pounds in lost stock.
With early awareness, you can move stock, avoid unnecessary door opening, start a generator, or relocate items to backup storage before temperatures reach unsafe levels.
Perfect For
- Home fridges & chest freezers
- Restaurants, cafés, bars and takeaways
- Butchers, delis and food prep areas
- Small cold rooms and walk-in freezers
- Holiday rentals & Airbnb hosts
Food Businesses & Compliance
For commercial kitchens and food retailers, a power outage isn’t just inconvenient — it’s a food safety issue. PowerNotify helps you stay on top of potential breaches before they become a problem for HACCP logs, inspections, or customer safety.
- Reduce the risk of having to dispose of full freezers of stock
- Support your existing temperature monitoring routines
- Provide evidence that you acted quickly when an outage occurred
How It Works
- Plug in. Power the device from any USB adapter near your refrigeration equipment.
- Connect to Wi-Fi. Use the quick start to connect the device to your network.
- Set recipients. Add email addresses and phone numbers in the cloud portal.
- Get alerted. If the device heartbeat stops for your chosen window, we notify you instantly.
Without vs With PowerNotify
| Scenario | Without PowerNotify | With PowerNotify |
|---|---|---|
| Overnight power cut | You discover warm stock in the morning and may have to dispose of everything. | You receive an alert, can visit or call staff, and move stock or start backup power. |
| Weekend outage | Fridges sit without power for days, spoiling unnoticed. | You’re alerted wherever you are and can arrange access for someone to check. |
| Short interruptions | You may never know why temperatures drifted in your log. | You have a clear record that power or internet was lost at a specific time. |
FAQ
Will it work if my internet goes down?
Yes — loss of power or internet both stop the heartbeat. If the cloud doesn’t hear from your device within your alert window, you’ll be notified.
Do I need a sensor inside the fridge?
No. PowerNotify detects power or connectivity loss. For temperature monitoring, you can run a separate probe, but most users just need outage alerts to act quickly.
Can I use one device to protect multiple fridges?
Yes. Many users power a single device from a USB adapter near a bank of fridges or a small cold room. If power or internet is lost at that location, you’ll still receive alerts.
