Free 30-day pilot · no contract
We'll watch your walk-in for 30 days. Free.
A compressor that dies at 2 a.m. isn't found until the morning open, and by then the load is gone. We install temperature monitoring on your coolers and freezers, you get alerts the moment something drifts out of range, and after 30 days you tell us whether it earned its place. If it didn't, we pull it out and that's that.
How it works
Four steps, one visit.
A 15-minute call
How many coolers, what's failed before, who should get the alerts. If it's not a fit I'll tell you on that call rather than waste your afternoon.
We install
About 30 minutes. A probe in each unit you want covered, and the monitoring software on a back-office computer you already keep on. If you would rather I supplied a dedicated mini-PC, or did the install and cable routing for you, those are quoted up front — the 30 days of monitoring itself is free either way.
30 days of watching
Alerts by email the moment a unit drifts out of its safe range, day or night — or to Slack, Teams or your own system via webhook. One screen shows every cooler live, with its history.
You decide
Did it catch anything? Was it a nuisance? The probes are loaner equipment, so they come back at the end either way — assembled units are not offered for sale until FCC authorisation is complete, and I’ll tell you the day that changes. If you’d rather not wait, the DIY kit is available now. You owe nothing for the trial.
What you get
Alerts while the food is still good.
Out-of-range alerts
Each unit gets its own safe high and low, pre-set for cooler or freezer. A cracked door, a dying compressor, an iced coil — you hear about it in minutes, not at the morning open.
A silent probe is an alarm
If a probe loses power or Wi-Fi, that silence itself raises an alert. A dark freezer never quietly passes as "fine".
The log, automatically
Every reading recorded and exportable to a spreadsheet whenever you want it — less clipboard time for your staff, and a record you actually have when someone asks.
Your data stays yours
Readings live on your machine, in your building. No account, no cloud service, no subscription, and no vendor who can switch it off or put the price up.
No surprises
What this is, and what it isn't.
You are letting a stranger put equipment in your kitchen, so here is the part most vendors leave for the small print.
What we need from you
- A spot for the hub computer on your Wi-Fi, and access to place the probes.
- About 30 minutes for setup, and a name and number for whoever should get alerts.
- Your honest feedback at the end — did it catch anything, was it easy, what would you actually pay for it.
What it is not
- It is an operational monitoring and loss-prevention tool. It is not a certified, NIST-traceable or health-code compliance instrument, and it does not replace your required manual checks or official records.
- Everything runs on power. A full outage stops monitoring — though your coolers are off then too. We can put the hub on a small battery backup if that matters.
- Alerts that leave the building ride your internet. If the WAN drops, the on-screen alarm still shows but email pauses until it is back.
Why you can trust the numbers
Built and tested in the open.
This isn't a rebadged import. The hardware, the firmware and the software are designed here, the source is public, and the field testing is published — including what it got wrong. Three probes logged 430,022 readings across two days; the same run surfaced a timestamp bug, which is written up alongside the good numbers rather than quietly dropped.
Book it
Two coolers or twenty — same offer.
Tell me how many units you want covered and when suits for a 15-minute call. I run these one kitchen at a time, so there are a limited number of pilot slots.
