Temperature Monitoring & Data Logging Australia

One vendor-neutral engine: installed, integrated, reporting.

We design it for your sites, fit it to the gear you already run, monitor it, and keep the evidence trail auditors actually accept.

One dashboard for everything

Every fridge, freezer, coolroom, rack and site in a single view, on the phone, tablet or computer, each with its own safe range. The point of a hub is that you stop logging into five things.

install

Instant alerts, to the right people

SMS, email or app push the moment a temperature crosses your line, a door is left open, or power drops. Escalate to a second and third contact if the first doesn't answer.

alert

Audit-ready records, automatic

Continuous, timestamped logging you can export on the spot: HACCP-ready reports, Strive for 5 history, data-centre logs. The evidence is built, not chased.

report

Works when power and internet don't

The category's real differentiator. Battery backup plus cellular failover means the alarm still fires during the exact event, blackout, router down, after-hours, when most failures actually happen.

failover

Fits your existing gear

Wireless sensors retrofit to the fridges, freezers, coolrooms and racks you already own. No new equipment to buy, no cabling to trench, no brand lock-in.

retrofit

Installed and monitored for you

Professionally installed, actively monitored, real people on Australian networks. Multi-site rollup, so head office sees every location at once.

monitored

The same panel, re-framed for each thing you're responsible for.

They look like five different problems. They're one engine, with one safe range set per asset. Switch environments and watch the panel re-frame.

Walk-in fridge, kitchen 3.2°C

Food & hospitalityAt or below 5°CLogged every reading

The walk-in fridge, holding the line.

The cafe's cold stock has to sit at or below 5°C, all day, every day. The panel watches the reading and quietly builds the FSANZ log, so the clipboard you used to fill twice a day fills itself.

Food safe. FSANZ Food Standards Code 3.2.2A: cold food at ≤5°C, with continuous logging replacing the daily clipboard.

Chest freezer, dry store −20°C

Frozen stockHold below −18°CDoor-open alerts

The freezer, the same way.

Same engine, different safe range. A door left ajar or a slow thaw is the kind of thing nobody notices until prep, except here it has already fired an alert.

Frozen, and proven. Hold below −18°C: a door ajar or a slow climb shows up long before the stock thaws and the loss becomes a write-off.

Walk-in coolroom 2.8°C

Biggest overnight riskPurpose-built spoke

The coolroom, where the real money sits.

A walk-in room full of stock is the biggest overnight risk you carry. For these we point you at Coolroom Alarm, the purpose-built spoke, and it still rolls up into this one view.

The walk-in room. A coolroom full of stock is the single biggest overnight loss. Coolroom Alarm is purpose-built for it, and rolls up here.

Vaccine fridge, pharmacy 4.6°C

Pharma & vaccine+2°C to +8°CTarget +5°C

The vaccine fridge, in its narrow window.

+2°C to +8°C, target +5°C, Strive for 5. The same panel now frames a different rule, logs for review, and raises a back-to-base alarm the moment a reading drifts.

Cold chain. National Vaccine Storage Guidelines (Strive for 5): hold +2°C to +8°C, log and review, and manage a breach the moment it happens.

Server & comms room 22°C

Server & comms18°C to 27°CUptime & insurance

The server room, nothing cold about it.

This one is about uptime and insurance, not stock. We keep the rack inside the ASHRAE 18°C to 27°C envelope and catch an aircon failure early, alongside Sydney IT. One engine, across every cold thing, and the warm one too.

Uptime, not just stock. ASHRAE recommends roughly 18°C to 27°C. Catch an aircon failure before it becomes downtime.

The failures all happen when nobody's looking.

A fridge, a coolroom or an aircon doesn't pick business hours to die. It goes overnight, on the weekend, in a blackout, and you find out the hard way.

02:00 → 06:40

You find out at morning prep

The coolroom failed at 2am. By the time someone opens up, the stock is warm, it all goes in the bin, and there's no record to show the auditor what happened.

overnight

A vaccine fridge drifts overnight

A twice-daily paper chart can't catch an after-hours excursion or a quiet power loss. One drift outside +2°C to +8°C and the stock has to go.

hours baking

The aircon dies and cooks the rack

In a server or comms room the first sign of an aircon failure is usually downtime, not a warning. By then the hardware's already been baking for hours.

audit day

Paper logs the auditor rejects

Hand-written checks have gaps, get missed on busy days, and can't be trusted. Auditors increasingly want continuous, timestamped records, not a clipboard.

Now replay the same night, monitored.

The coolroom still fails at 2:07am. What changes is everything after.

02:07The coolroom crosses 5°C
A power dip stops the compressor. The reading starts climbing. The sensors keep logging on battery.
02:07The SMS goes out
The on-call phone gets the alert over the cellular link. The wifi died with the power, and it didn't matter.
02:09Someone acknowledges
No acknowledgement within your window and it escalates to the second contact, then the third.
02:41Back in range
Stock moved or the tech is on the way, and the whole event sits timestamped in the log for the auditor.

Total time warm: 34 minutes. The unmonitored version of this story ends at morning prep, four and a half hours later, over a bin.

What does one warm night cost?

Put your own numbers on the 2am failure. The maths is just the FSANZ 2-hour/4-hour rule applied to your stock.

Cold stock on hand$8,000

Without monitoring, when would you find out?

Guide only, based on the FSANZ 2-hour/4-hour rule for potentially hazardous food held above 5°C. The call on the night is always made item by item.

The unmonitored outcome

$8,000 gone

About 4.5 hours out of temperature control. Under the FSANZ 2-hour/4-hour rule, stock that has sat above 5°C for 4 hours or more can't be saved. It's a write-off, plus the restock and the gap in your records.

The monitored version: an SMS at 02:07, someone acting well inside the window, and a timestamped log to prove how you handled it.

The same engine, three different rulebooks.

We keep the numbers honest: the system gives you the records and the alerts, the compliance obligation stays with you. Each environment just gets its own safe range and its own report.

How it works.

We map your cold spots

Tell us your fridges, freezers, coolrooms, racks and sites. We work out what to monitor and the safe range for each.

We install it

We fit wireless sensors to your existing gear, set up the dashboard, set your alert thresholds and escalation, and test the failover. One visit, done properly.

You stop guessing

Live temperatures and history on your phone, alerts when it matters, and audit-ready reports a click away. We watch it and back you up.

Who it's for.

If a temperature drifting out of range costs you stock, patients, hardware or an audit, you're who this is built for.

Food & hospitalityCafes, restaurants, QSR, catering and grocers who can't afford to bin a coolroom of stock or fail an audit.

Pharmacy & medicalPharmacies, GP clinics and aged-care protecting vaccines and medication against an after-hours excursion.

IT & server roomsMSPs and in-house IT who need a warning before an aircon failure turns into downtime.

Labs & logisticsResearch and cold-chain operators who need a continuous, tamper-resistant evidence trail for GMP and GDP.

Built by people who run networks and sensors for a living.

Temperature Monitoring is an Alien IT company, run by Alien IT Solutions, 18 years building networks, sensors and connectivity around Australia. For walk-in coolrooms, our spoke Coolroom Alarm is purpose-built. Server and comms rooms are handled by Sydney IT. Hardware at the Alien IT Store.

Where this comes from

The primary sources behind the above, so you can check any of it yourself rather than take our word for it:

Food Standards Australia New Zealand, the bi-national agency that develops the food standards used here.
FSANZ: food safety standards for business, the plain-English entry point for what applies to a food business.
The Australia New Zealand Food Standards Code, where Standard 3.2.2A and the temperature control provisions actually live.
NSW Food Authority, the state regulator that enforces the Code in New South Wales.
Department of Health: National Vaccine Storage Guidelines, Strive for 5, the source for vaccine storage and monitoring.
Cold chain and data logger, background on the terms used throughout this page.

Questions people ask.

Will it still alert if the power or internet goes out?

Yes, that's the whole point. The sensors and gateway have battery backup and a cellular failover, so an alert still fires during a blackout or when your router or wifi is down. It does not depend on your internet to raise the alarm.

Does this make me HACCP or Strive for 5 compliant?

It gives you the continuous records and the alerts that support compliance, but the legal obligation stays with you. We provide audit-ready, timestamped evidence aligned with HACCP, Food Standards Code 3.2.2A and the Strive for 5 vaccine storage guidelines. We don't sell a certification.

Who gets the alert and how fast?

Whoever you choose, by SMS, email or app push, within moments of a temperature crossing your set range. You can escalate to a second and third contact if the first person doesn't acknowledge it.

Will it work with my existing fridges, coolrooms and racks?

Yes. We fit wireless sensors to the equipment you already own, fridges, freezers, walk-in coolrooms and server racks. There's no new fridge to buy and no cabling to run.

Can one dashboard cover multiple sites and different room types?

Yes, that's the hub promise. Food fridges, a vaccine fridge and a server room across several locations all roll up into one view, so head office sees everything at once.

What can the temperature monitoring system cover?

One temperature monitoring system covers fridges, freezers, vaccine fridges, server and comms rooms and cold-chain storage. Each gets its own thresholds and audit-ready logging, so a fridge temperature monitoring system, freezer monitoring and server room monitoring all run from the same dashboard.

What does it cost?

It's an install plus a monitored plan, and it depends on how many sensors, sites and room types you need, so we quote per business rather than guess. Tell us your setup on the contact form and we'll come back with a real number.
