Temperature monitoring for Australia: fridges, coolrooms and server rooms.

A plain guide to keeping fridges, coolrooms, server rooms and vaccine fridges in range: how the sensors work, how you get an alert before stock is lost, what records auditors want, and how it keeps working when the power and internet don't.

What is temperature monitoring?

Temperature monitoring puts a wireless sensor in each fridge, freezer, coolroom or rack, brings every reading onto one dashboard, and raises an instant alert the moment a temperature drifts out of the safe range you set. Every reading is logged, so you also get a continuous, timestamped record you can hand an auditor.

The point is to know while you can still act, not at morning prep when the stock is already gone, and to have the evidence either way.

Where it's used, and the rules that apply.

The tool gives you records and alerts. The compliance obligation stays with you.

Food service

Cold ≤ 5°C · Hot ≥ 60°C

Cold food at or below 5°C, hot food at or above 60°C, with the danger zone in between. Continuous logs support HACCP and Food Standards Code 3.2.2A (in force since December 2023), so your records are audit-ready instead of a clipboard with gaps.

Pharmacy & vaccines

+2°C to +8°C · target +5°C

Vaccines held between +2°C and +8°C, target +5°C, with a back-to-base alarm for excursions, power loss or a door left ajar. Supports the National Vaccine Storage Guidelines (Strive for 5), with continuous logging at regular intervals.

Server & comms rooms

18°C to 27°C · ASHRAE

Keep racks inside the ASHRAE recommended 18°C to 27°C envelope. Catch an aircon failure before it becomes downtime, with the server-room side delivered by our parent Alien IT Solutions and Sydney IT.

Labs & cold-chain

GMP & GDP aligned

Continuous, tamper-resistant records for storage and transport, aligned with TGA Good Manufacturing Practice and Good Distribution Practice, so a single excursion has a clear evidence trail.

Rental & property

Habitability & humidity records

Australian states are tightening rental habitability standards: heating and cooling minimums, damp and mould, ventilation. Property managers increasingly have to prove a place stayed within those minimums, not just say it did. Continuous temperature and humidity logs, with exportable compliance reports, do that for you. When a tenant dispute lands or a mould claim gets argued, a dated record beats your word against theirs every time. Set a safe range per property, log it around the clock, and pull a clean report when someone asks: an inspector, an insurer, a tribunal. It is the same monitor-and-export story the rest of this page argues, pointed at rentals instead of fridges. Know a property is drifting out of habitable range while you can still act, and have the evidence either way.

How it works.

A sensor in each space

A wireless sensor measures the temperature and runs for a long time on its own battery, retrofitted to the fridge, freezer, coolroom or rack you already own.

Readings to one dashboard

Readings reach a gateway and roll up to one multi-site dashboard. Battery backup and cellular failover keep it reporting through a blackout or a dead router.

Alerts and a record

Cross the safe range and you get an SMS, email or app alert, escalated to more contacts if needed, while every reading is logged for audit-ready reports.

What actually matters when you choose.

Does it survive a blackout?

Most failures happen during power or network loss. If the alarm needs your wifi to fire, it's silent at the worst moment. Insist on battery backup and cellular failover.

Are the records audit-ready?

Auditors increasingly reject paper logs for gaps and illegibility. You want continuous, timestamped, exportable records you can pull on the spot. Be specific about the artifact: a dated PDF export, say a 90-day temperature history, that you hand straight to an inspector or attach to an insurance or stock-loss claim. That's the deliverable, not a vague promise of "records". When a claim hangs on proving the fridge held range until 2am and failed after, that single PDF is the difference between paid and denied. Ask any system you're weighing up to show you the export, on the spot, before you buy. If it can't produce a clean dated PDF in front of you, it won't produce one for the inspector either.

Is it monitored or just logging?

A logger you read once a week is a post-mortem. A monitored system alerts a human while there's still time to act. That's the difference. Need instant alerts when a cool room goes out of range? See cool room alarms at coolroomalarm.com.au.

One view across sites?

If you run more than one location or room type, you want a single rolled-up dashboard, not a folder of separate logins and paper.

Who builds it.

Temperature Monitoring is an Alien IT company, run by Alien IT Solutions, an Australian IT and networks business with more than 18 years of experience. For walk-in coolrooms, our spoke Coolroom Alarm is purpose-built. The server and comms-room side is handled by Sydney IT. Hardware is available from the Alien IT Store.

Questions people ask.

How does temperature monitoring work?

A wireless sensor in each fridge, freezer, coolroom or rack measures the temperature and sends it to one dashboard. You set a safe range for each, and the system raises an SMS, email or app alert the moment a reading drifts out of range, a door is left open, or power fails. Every reading is logged so you have a continuous, timestamped record.

Does it work when the power or internet goes out?

Yes. The sensors and gateway run on battery backup with cellular failover, so an alert still fires during a blackout or when the router or wifi is down. It does not depend on your internet to raise the alarm, which matters because most failures happen exactly when the power or network is out.

Does it make me compliant with HACCP or Strive for 5?

It provides the continuous records and alerts that support compliance, but the legal obligation stays with you. The system produces audit-ready, timestamped evidence aligned with HACCP and Food Standards Code 3.2.2A for food, and the Strive for 5 vaccine storage guidelines for pharmacy. It is not a certification.

What temperatures should each environment hold?

Cold food should sit at or below 5°C and hot food at or above 60°C. Vaccines must stay between +2°C and +8°C, target +5°C. Server racks are commonly kept in the ASHRAE recommended 18°C to 27°C envelope. We set each safe range to suit your equipment.

Who installs and supports it?

Temperature Monitoring is an Alien IT company, run by Alien IT Solutions, an Australian IT and networks business with more than 18 years of experience. Alien IT designs, installs and monitors the sensors, the gateway and the dashboard, with local Australian support.
