Cold-Chain Watchdog: an independent guard for fridges and freezers

what happened

11–12 October: about 700 French supermarkets. Freezers pushed to 50 °C overnight.

2 November: again, across seven countries. In Ireland, at least 13 SuperValu stores.

If one system runs the fridge, the alarm and the record, one break takes all three.

It watches the cabinet, not the controller.

Separate from your controller, your network and your monitoring vendor.

Its own cellular link and battery backup, so it still reaches you when the store network does not.

You are told when a defrost starts that nobody asked for.

No password to guess, no port to find, it takes no commands.

Every reading is signed on the device, so a tampered record can't hide. Ready for insurers and food-safety inspectors.

Pulling the plug or opening the case raises the alarm.

Join the list. Takes a minute. No payment.
We write back with a few questions about your cabinets and how you monitor them today.

You tell us what works and what doesn't. That shapes what we build next.
