Can I get a fridge or freezer alarm that works without WiFi in Canada?
Yes. Choose an alarm with its own cellular connection, so it needs no WiFi, router or landline. The MaxLinc EDGE Essential Cellular has a built-in cellular link and runs about 1 year on 4 AA batteries (USB-C power optional). When the temperature crosses your limit, it phones, texts and emails everyone on your list and sends an app notification. The 1st year of cellular service is included, then about $26.67/yr per device, billed annually. To put probes inside a fridge or freezer, choose EDGE Thermo Cellular.

What to look for in an alarm without WiFi
Its own cellular link
A cellular alarm sends its alerts without your internet. It needs cellular signal where it sits, so check your phone’s signal at that spot.
Batteries, not just an outlet
An alarm that only runs plugged in can go quiet in a power cut. EDGE runs on 4 AA batteries, and on USB-C power the Cellular models report a power cut at the next recording (every 10 minutes by default).
Calls, not just texts
A phone call wakes you up. EDGE calls and texts everyone on your list; about $3.70 of call and text credit is included (250 texts or 100 calls).
The real yearly cost
Count the device and the plan it needs. EDGE Cellular includes year 1, then costs about $26.67/yr per device.
Probes for inside the appliance
A room sensor reads the air around it. EDGE Thermo puts two probes inside a fridge and a freezer, −55 to +125 °C (−67 to +257 °F), with the cables through the door seal.
A screen you can read on site
The EDGE e-ink screen shows the reading on the device. Below 0 °C (32 °F) it stops updating and says so; logging and alarms carry on.
Pick your EDGE
Every EDGE alerts your list by phone call, text, email and app and logs every reading. Choose WiFi, or Cellular where there is no WiFi.

More questions
Does a cellular alarm work everywhere in Canada?
It needs cellular signal where the device sits, so check your phone’s signal at that spot before you buy. If it does not work out, our 30-Day Money-Back Guarantee covers you: send back any unused item in its original packaging within 30 days and we pay the return shipping.
Is there a monthly fee?
On Cellular, the 1st year of service is included, then about $26.67/yr (about $2.22/month) per device, billed annually; it covers the cellular network and Premium. Nothing is charged before year two. Email and app alerts are always free; texts and calls use the included about $3.70 credit.
What happens in a power cut?
Every EDGE runs on 4 AA batteries, so it keeps logging through a power cut. A Cellular model on USB-C power reports the power cut at its next recording (every 10 minutes by default) by app notification, email and text, over its own cellular link, so the alert does not depend on your router.
Can it also use WiFi?
Yes. Every EDGE Cellular model can also use WiFi. If there is WiFi where it goes and outages don’t worry you, EDGE WiFi has no subscription.
Where does it ship from?
A Canadian EDGE order ships from within Canada, so it never goes through customs. It is charged in Canadian dollars, with free shipping over $100.
