Clever Logger to Gateway-to-Internet

Traditional loggers have to be manually downloaded to get their data.

Clever Logger changes that. The loggers broadcast their readings electronically. The gateway receives the readings and saves them to the internet every few minutes.

This gives you a “live” log of temperatures available on any internet device (computer, tablet, phone), anywhere in the world via a simple web site.

The website also gives you immediate alerts about problems, and automatic reports to your email inbox.

Is this logger right for you?


This logger is ideal for small fridges and freezers.

  • Vaccine and blood fridges
  • Domestic fridges
  • Drinks fridges
  • Glass fronted supermarket fridges and freezers
  • Cold display cabinets
  • Commercial kitchen fridges (e.g. underbench fridges)

What about commercial cool rooms and walk-in freezers?

The logger needs to get a radio signal (Bluetooth) to the gateway. It can be difficult to get a signal out of a cool room so you may need a logger with an external probe.
