Commercial fridge, refrigerator & freezer alarm, AustraliaKnow before it spoils.
A small sensor sits inside your fridge or freezer. The moment the temperature drifts, your phone gets an SMS, then a call, until a human answers. Commercial kitchens, cafes, medication fridges, home brew: if it matters, it gets watched all night.
Plugs into a power point. WiFi with 4G and battery backup. Installed in about ten minutes.
Reading every 15 seconds. Logging every 15 minutes. Forever.
The 3am failure is the one that costs you
A fridge never fails at a convenient time. The compressor gives up overnight, the door does not quite click shut, someone trips the wrong switch on the way out. You find out at 7am, standing in front of warm stock, and by then the only question is how big the bin bag needs to be.
Fridge Alarm exists so you find out at 3.02am instead, while the stock is still cold and the fix is still a two minute job.
One bad night, minute by minute
Here is exactly what happens the night a fridge gives up: what the sensor sees, what the hub does about it, and what your phone hears. Follow the timestamps.
-
the probe · reads every 15 seconds 2:47amThe compressor gives up
Nothing dramatic. A relay sticks, a fuse quits, someone bumped a switch on the way out. The kitchen is dark and silent, and the only thing that notices is the sealed probe on the middle shelf, reading the air every 15 seconds like it has since the day you dropped it in. No wiring, nothing to void a warranty. It just watches.
-
the drift · safe range 0 to 5°C 2:58amThe drift crosses the line
Eleven minutes later the air passes 5 degrees. The alarm knows the difference between this and a door opened for a restock, because you set a safe range and a grace window for each fridge. A quick delivery wakes nobody. A compressor that stays quiet does.
-
battery backed · heartbeat if it ever goes silent 3:02amThe hub gets the word out
The hub sends the alert over your WiFi. If the power is out it runs on battery, and if the internet went down with it, it falls back to 4G. If the whole unit ever goes silent, a heartbeat alert tells you that too, so silence never means everything is fine.

the alert panel · SMS → call → second contact 3:07amIt rings until a human answers
A text first. No reply in five minutes, your phone rings. Still nothing, it rings your second contact. The alarm does not give up at one missed notification, because at 3am the first one usually is.

the log · wrote itself while you slept 3:41amBack in range, all on the record
The door gets reseated, the temperature falls, and the whole excursion is already in the log: the alert, the call, the corrective action, the recovery, all timestamped. The auditor gets a spreadsheet. You get back to sleep.
This is the dashboard doing its job
Real product, simulated fridge. Press the button and watch a failure unfold the way it would on your phone: the drift, the alert, the escalation, the log entry. Nobody has to be watching a screen, the alarm does the watching.
The temperature log writes itself
Paper logs get skipped on the days you are busiest, which are exactly the days the auditor asks about. Fridge Alarm records every reading, flags every excursion, and keeps the corrective action next to it. When someone asks for the records, you export a spreadsheet instead of hunting for a clipboard.
| Date | 4:00am | 2:00pm | Status | Corrective action |

Running a pharmacy, a vaccine fridge or a multi-site food business? That work belongs with our big sibling, Temperature Monitoring. Got commercial coolrooms? See Coolroom Alarm.
What does one silent failure cost you?
Insulin or other medication in the fridge? The dollars stop being the point. Count the trip to the GP for new scripts and the days without it.
That is what you are betting every night the fridge runs unwatched. The alarm rings you at the first degree of drift, while everything inside is still cold.

Cafes & food retail
Your margin lives in two fridges and a chest freezer. One warm night eats a week of profit and the morning trade with it. The alarm rings you while the stock is still saveable, and the HACCP log keeps itself for the inspector.
Medication fridges at home
Insulin, EpiPens, kids' scripts. A tripped switch or a tired seal should be a phone buzz at 10pm, not a discovery at breakfast. Set the safe range once and the fridge is watched every night after.
Home brew & serious fridges
A fermentation fridge two degrees off ruins a month of work. Watch the batch from your phone, get alerted the moment it drifts, and keep the temperature history to show exactly how the good batch was done.
Fridge alarm questions, answered straight
Does it work with any fridge or freezer?
Yes. The sensor is a sealed probe that sits inside any brand of fridge, freezer or drinks cabinet, domestic or commercial. No wiring into the appliance, nothing to void a warranty.
What happens if the WiFi drops out?
The hub keeps logging on battery and falls back to 4G to send alerts. You also get a heartbeat alert if the unit itself goes quiet, so silence never means everything is fine.
Will it wake me at 3am because someone left the door ajar?
Only if you want it to. You set the safe range and a grace window for each fridge, so a quick restock does not trigger anything, but a door left open at closing time rings your phone before the stock is lost.
Is the automatic temperature log good enough for a food safety audit?
The log records what an auditor asks to see: time, temperature, the excursion and the corrective action. Export any date range as a spreadsheet in one tap instead of chasing a paper sheet on a clipboard.
How hard is it to install?
About ten minutes. Put the probe in the fridge, plug the hub into a power point, connect it to your WiFi and you are protected. No electrician, no drilling.
What does it cost?
The alarm is a one-off purchase and monitoring is a small monthly plan. Tell us what you are protecting and we will send you a straight quote the same business day.
Is this a commercial fridge alarm system or a home one?
Both. The same refrigerator alarm system runs a single home fridge or every reach-in and display fridge in a commercial kitchen, each with its own safe range. The first alert is an SMS, then a call, so it reaches whoever is on call without anyone watching an app. For a walk-in cool room or freezer room, use Coolroom Alarm instead.
