Is there a freezer alarm that calls or texts my phone?

Yes. When a probe crosses your limit, the MaxLinc EDGE Thermo WiFi phones, texts and emails everyone on your list, sends an app notification and sounds a buzzer on the device, and the alarm repeats until the reading is back in range. Its two probes go inside a fridge and a freezer, −55 to +125 °C (−67 to +257 °F). There is no subscription on WiFi. Each device includes about $3.70 of call and text credit (250 texts or 100 calls), then about 1.5¢ per text and about 3.7¢ per call.

What to look for in a freezer alarm that calls you

  • A real phone call

    Texts are easy to miss at night. EDGE places a phone call as well as a text, an email and an app notification.

  • Everyone who needs to know

    On WiFi the list is unlimited in year 1; after that, adding new people needs Premium, and people already on the list keep their alerts.

  • It repeats until fixed

    The alarm repeats until the reading is back in range. A team member can snooze it for up to 24 hours by acknowledging it and entering a reason.

  • A probe inside the freezer

    A probe reads the freezer itself, not the room. EDGE Thermo has two, so one device watches a fridge and a freezer; run the cables through the door seal.

  • An alarm you can hear on site

    The buzzer and the on-screen alarm tell whoever is nearby, even before they check a phone.

  • Works in a power cut

    EDGE keeps logging on 4 AA batteries. For alerts that never depend on your router, choose EDGE Thermo Cellular.

More questions

How much do the calls and texts cost?

Every device comes with about $3.70 of call and text credit (250 texts or 100 calls): about 1.5¢ per text and about 3.7¢ per call, so an alert that calls 3 people and texts 5 more costs about 19¢. Email and app alerts are always free.

Is there a subscription?

No subscription required on WiFi. Alarms, live data, 45 days of history and Excel export stay free. Optional Premium adds full history and adding new people for about $17.78/year per device, billed annually, and your first year of it is included. On Cellular, the 1st year of service is included, then about $26.67/yr per device.

Will the probe cable damage my freezer door?

Run the cable through the door seal and check that the door still closes tight.

What if my WiFi is down?

A WiFi model can only send alerts while your router and internet work, and it keeps logging on its batteries meanwhile. If the alarm must get out no matter what, choose EDGE Thermo Cellular: it uses its own cellular link.
