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 reportVaccine 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.
ScheduledFood 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.
ScheduledHourly 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 reportTransport 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 demandDetailed 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 reportVapor 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 reportPeak 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 reportLight 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 reportCustom 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 demandMulti-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.
ScheduledAI 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.
Running more than a few fridges? There's a lot more inside.
Tap a feature to see how it works.
Automatic reports by email
Schedule a supported report to generate on a recurring basis and be emailed to the people who need it. Reports are built on the server, so a multi-thousand-row export never ties up your browser — and it keeps arriving whether or not anyone remembers to run it.
- 1Choose the report and periodPick the report type and the reporting window — a day, a shift, a week, a month.
- 2Set the recurrenceHow often it runs and at what hour, in the recipient’s own time zone.
- 3Pick format and recipientsPDF, Excel or both — to you and to everyone the device is shared with.
- 4Then leave it aloneIt generates in the background and emails on time. If a report cannot be generated you are told, so silence is never mistaken for compliance.
Automatic and scheduled reports are a Premium feature - free for the first year with every device.
Smart alarm tuning
A monitoring system that cries wolf gets muted, and a muted system protects nothing. Every threshold, delay and filter is adjustable per device and per parameter, from the same screen you watch the readings on.
- 1Instant AlarmsImmediate alarm if a parameter goes above max or drops below min threshold.
- 2Persistent ConditionFilters out brief fluctuations — alarms only if the condition persists.
- 3Time-Weighted AverageMonitors long-term exposure compliance.
- 4Trend Drift DetectionDetects gradual drifts from historical baseline data.

Min and max thresholds per parameter
Independent high and low limits for temperature, humidity, CO2, current, pressure and every other channel on the device.
Alarm trigger delay
How long a reading may stay out of range before anyone is contacted — enough to let a door close or a defrost cycle finish.
Persistent-condition filter
Notify immediately, or wait an hour and only raise the alarm if the parameter is still out of range.
Time-weighted average
Watch cumulative exposure instead of instantaneous spikes, for limits that are written as an average over time.
Trend drift detection
Compare rolling 30-minute time-weighted averages back through a window you choose and alarm on a percentage of change — this catches slow failures that never break a threshold.
Connection-loss alarm
Raise an alarm when a device misses its scheduled upload, separately from the measurement alarms.
Audible on-device alarm
Make the logger itself beep on site. It costs battery, so it stays yours to switch on.
Alarms on or off per device
Silence a unit that is in transit or on a bench without touching anyone else’s setup.
Changes you make in the web app sync down to the hardware on its next upload, and the device card stays blue until the new settings are confirmed on the device itself — so you always know what the logger is actually running.
Team roles and permissions
Share any device with as many people as you need (with Premium, included for every device's first year). Everyone gets their own login, their own language and time zone and their own notification preferences — and exactly the level of control you grant them.
Viewer
Sees everything, changes nothing
Full read access to live readings, history, charts, maps and reports — and they receive alarms. The default for anyone who needs the numbers but must not touch the configuration.
Editor
Full operational control
Everything a Viewer can do, plus renaming the device, adjusting alarm thresholds and delays, setting record and sync intervals, adding notes and exporting the activity log.
Silent Viewer
Watching, without the pager
Identical visibility to a Viewer with alarms switched off for that person. Built for executives, auditors and analysts who need the data but must not be woken by it.
Service & Maintenance
The technician who fixes it
Configuration rights like an Editor, plus the service side: logging repairs, parts and costs against the asset. One designated service partner per device, and the account has to be registered as a service partner.

Combine sensors in one report
Sensors rarely sample in lockstep — one logs every 5 minutes, another every 15, a third woke up 40 seconds later. Multi-Sensor Data Consolidation aligns them into a single time-indexed dataset so they can be compared, subtracted and audited together.
Aligned time slots
Closest-record matching
For each time slot, take the reading nearest that timestamp on each device. Every value stays a real, measured number — nothing is invented.
Linear interpolation
Estimate each device’s value exactly on the time slot from the readings either side. Produces perfectly aligned curves for differencing and correlation.
Digital twin and repair history
A sensor gives you a number. The digital twin tells you what that number is attached to: which pump, in which zone, in which building, installed when, serviced by whom, and how healthy it is right now.

- When the work happened.
- Technician
- The crew member or partner who did it, from your saved team.
- Work completed
- What was actually done, in plain words.
- Parts replaced
- Each part by name, quantity and unit cost.
- Labour and parts cost
- Totalled per visit and rolled up across the life of the asset.
- Downtime
- Hours the asset was out of service.
- Warranty
