What 3 a.m. looks like with MaxLinc

Example alert. You name your devices and set your own limits.
“The phone call alarm feature is outstanding. We had a cooler issue after hours and responded before inventory was affected.”
Fatima W.Review of EDGE Thermo WiFi

Built so nobody sleeps through it

  • Each person picks how

    Call, text, email or push - or all four. Set in their own profile, language and time zone.

  • Set per device

    The walk-in alarms the kitchen crew. The vaccine fridge alarms the pharmacist. No noise for anyone else.

  • Silent Viewer for the boss

    Sees every reading and every report. Never gets the 3 a.m. call.

  • Dead battery? Lost signal? You'll know.

    A reminder when the batteries run low, and a connection-loss alarm if a logger misses its upload. A dead logger never passes for a healthy fridge.

Worried about power outages?

A power cut takes your WiFi router down too. Plug EDGE Thermo Cellular into USB-C and it alerts you within minutes of a power cut, over its own cellular link, while its AA batteries keep it running.

What customers say about the alarms

    Harpreet B.Review of EDGE Thermo Cellular
  • “Very good product. We had compressor problem at night and received phone call alarm right away. The software reports are clear and simple.”
    Carlos R.Review of EDGE Thermo WiFi
Every alarm, on the record

Who got the call. Who answered. What they did.

Anyone can tap Acknowledge and leave a note. The log keeps the name, the time and every call, text and email sent, and nobody can edit or delete it in the app. Not even the owner.

Daily summary+
See all 12 report types
  • Min / Max / Average Daily

    Summarizes daily minimum, maximum and average readings for each parameter — temperature, humidity and the rest. Daily averages make trend comparison and quick performance evaluation easy.

    Automatic report
  • Vaccine Temperature Report

    Tracks vaccine storage between pharmacy opening and closing times. Records opening and closing temperatures plus min/max since the last record, with optional Mean Kinetic Temperature (MKT) and vaccine out-of-range time.

    Scheduled
  • Food Safety Report

    Monitors food storage between operating hours. The basic report captures temperature at opening and closing; optional sections add RH, MKT, min/max, average and Food Safe Out-of-Range Time for HACCP and compliance audits.

    Scheduled
  • Hourly Report

    Reduced-resolution data for people who do not need every reading. Generates records at your chosen interval — every three hours, say — from the closest actual reading, with calculated metrics like Feels Like, EMC and Dew Point where the device supports them.

    Automatic report
  • Transport Log

    Records temperature and humidity from departure to delivery. Shows min, max and average for both parameters and calculates Food Safe Out-of-Range Time across the journey to verify cold-chain integrity.

    On demand
  • Detailed readouts

    Every recorded reading in full resolution for the selected period. Depending on the logger, it adds computed metrics such as Absolute Humidity, EMC or Heat Index.

    Automatic report
  • Vapor Pressure Deficit (VPD)

    Computes minimum and maximum VPD for day and night periods — built for greenhouse and agricultural monitoring, to keep transpiration and plant balance in the right window. Needs a logger that measures humidity.

    Automatic report
  • Peak Points Report

    Highlights the critical numbers: minimum, maximum and average within the selected interval. Useful for finding temperature extremes, environmental events or a fast diagnostic check.

    Automatic report
  • Light and UV Exposure

    Analyzes light and ultraviolet exposure over the selected period. Uses the chosen light-source profile to calculate relative UV levels, total absolute UV exposure and accumulated light dosage — so you can assess degradation risk for light-sensitive material and show daily limits were not exceeded. Needs a logger with a light sensor.

    Automatic report
  • Custom Interval Report

    A report at any fixed reading interval from 1 to 60 minutes, covering exactly the device channels you select, exported to Excel and PDF.

    On demand
  • Multi-Sensor Data Consolidation

    Combines several sensors into one synchronized report. Builds aligned datasets using closest-record matching or linear interpolation, so devices with different sampling intervals can be analysed side by side.

    Scheduled
  • AI Deep Dive

    An AI-written summary of sensor performance, anomalies and recommendations based on the last 30 days of data — executive summary, insights and recommended actions.

Questions before you buy

Can I see the app before I buy?

Yes. Press play on the 4-minute video tour of the real app on this page - no sign-up, no email. Or book a free live demo and we'll walk you through alarms, reports and sharing for your own setup. Call 888-365-8880 or use the contact form.

Will my phone actually ring?

Yes. Each person on the list picks an automated phone call, a text, email, push - or all of them. Alerts repeat until the reading is back in range. Switch on the device's buzzer and it sounds on site at the same time.

How many people can get the alarms?

As many as you want while the device has Premium (every device's first year, and always on cellular). On the free Standard tier, everyone already on the list keeps getting alarms, but adding someone new needs Premium. Recipients are set per device, and each person chooses their own channels, language and time zone in their own profile. Silent Viewers can see everything without being alerted.

Do texts and calls cost extra?

Email and push alerts are free and unlimited. Texts and calls use prepaid alert credit: a text is about 1.5¢ and a call about 3.7¢, so a 3 a.m. call to 5 people costs about 19¢. ~$3.70 is included with every device (about 250 texts), and every alert text shows your remaining balance. Top up anytime. If credit ever reaches $0, texts and calls pause until you top up, while email and push alerts keep going.

What happens if the power goes out?

When EDGE runs on USB-C power and that power drops, it sends a power-outage alert at its next recording (within 10 minutes at the default 10-minute recording interval, about a minute if it records every minute), and its AA batteries keep it logging and alarming. A building-wide outage also takes your WiFi router down, so if that alert must get out no matter what, choose an EDGE Cellular model: it has its own cellular link.

Will I know if the batteries run low or a logger goes offline?

Yes. You get a reminder when the batteries run low, and the connection-loss alarm tells you when a logger misses its scheduled upload. A dead logger never passes for a healthy fridge.

Does it work without WiFi?

EDGE Cellular models have built-in cellular with a global eSIM - no WiFi, router or internet needed. They can also use WiFi if you have it.

Is there a subscription?

Not on WiFi models: live data, every alarm, 45-day history and Excel export stay free. Premium (advanced and PDF reports, full history, sharing with new people) is free for the first year, then optional at about $17.78/year (about $1.48/month), billed annually. Cellular models include year one of service, then about $26.67/year (about $2.22/month), billed annually, with unlimited cellular data; nothing is charged before year two.

Do I need to install anything?

No. The MaxLinc app is a web app: open it in any browser on a phone, tablet or computer. Add it to your home screen and it behaves like an installed app, push alerts included. Nothing to download from an app store, nothing to update.

Can I give records to an inspector or auditor?

Yes. Download HACCP, vaccine and min/max/average reports as PDF or Excel (PDF and advanced reports are Premium, free for the first year), and export the alarm log for any period: every alarm, every message sent and every acknowledgement with its note. The log can't be edited or deleted from the app.

Where is my data stored?

In Canada, with daily backups and redundancy.

Your fridge won't call you. MaxLinc will.

The app is free with every device. 30-day money-back guarantee, 2-year limited warranty and free shipping over $100 to Canada and the US.
