Watched all night, even in a blackout
Your HABCOLog 2.0 checks your fridge every few minutes and sends its alarms over its own connection — no router, no Wi-Fi password, nothing for IT to set up. If it goes too warm or too cold for longer than the delay you set, it sends you an alarm.
Two clocks inside your logger
One clock writes down the temperature. The other sends it to the cloud. They run separately.
Recording Intervalhow often it saves a temperature
Leave it at 10 minutes. That is 144 saves a day, kept inside the logger.
Syncing Intervalhow often it phones home
Leave it at 24 hours. This sets when your chart fills in. Alarms do not wait for it.
Alarms jump the queue
Your logger does not sit on bad news until the next sync. It speeds up and sends the alarm.
Power messages jump the queue too
No internet? Still recording.
If the signal drops, the logger keeps writing temperatures in its own memory. When the signal returns, it sends everything.
Plug it in, sync faster
Your logger runs on four AA batteries. It behaves a little differently while it is plugged in.

When the power goes out
A power cut is when a fridge is most at risk. Your logger keeps working, and it tells you.
It keeps recording
It tells you quickly
You are told twice
Whether it reaches you depends on how the logger gets online

Who hears about it
Texts need two things
What to do about it
It watches itself too
A logger that has gone quiet is no use. Two things are checked for you, with no setting to switch on.
Low battery
Missed check-in
Two kinds of alarm
One rings at the first bad reading. The other waits to see if the problem is real.
Rings the moment one reading goes out of range. Very safe. Noisy when the door opens often.
Rings only if the fridge stays out of range for the whole 15 minutes. A quick door opening stays quiet.
One delay covers both directions
Change your alarm settings
Four steps. About two minutes. You only do this once.

Two ways to hear nothing
Share a fridge with colleagues
The level you pick decides what they see — and whether their phone rings at 2am.
Open the fridge’s settings
Same gear as before. Scroll to the section headed “Access and Ownership”. Find the “Share access” card and click “View and Add”.

Blue dot = our advice, not a published rule. The 2 °C and 8 °C limits come from published storage guidance (CDC, NIST and the Public Health Agency of Canada). The intervals and delays are ours; the other rows are simply how the app’s switches should be set.
One thing to check
Set the fridge to 5
Freezers: ask first
What “No Connection Alarm” does
Right way, wrong way
Do this · Limits
Do this: 2 and 8. The real safe range.
Not this · Limits
Not this: 0 and 10. Vaccines spoil before it rings.
Do this · Delay
Do this: 15 minutes. Ignores a door, catches a failure.
Not this · Delay
Not this: Six hours. A dead fridge stays quiet half a day.
Do this · Syncing
Do this: Leave it at 24 hours. Alarms still come at once.
Not this · Syncing
Not this: Flight mode. Nothing reaches you at all.
