Everything starts with a Starter Kit!

Let's get you up and running

A Clever Logger Starter Kit contains a Gateway and a Logger – everything you need to get you online and logging.

Choose from three types of logger:

  • Temperature only – our most popular logger and, most likely, the one you will need.
  • Temperature and Humidity – ideal for server rooms, ingredient and chemical storage, and food manufacture.
  • Temperature by External Probe – perfect for logging where wireless loggers can’t normally go – in metal enclosures (e.g. some cool rooms), in liquids (e.g. aquariums).


No more manual downloading

Clever Logger to Gateway-to-Internet

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

Clever Logger changes that. The Bluetooth loggers broadcast their temperatures and the gateway picks them up 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 on the Clever Logger web site.

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

Got more than one location to log?


Clever Logger is easy to scale up to any number of sites and loggers


Choose your extra Loggers

You will need one Logger for each location you wish to monitor.

e.g. If you have two fridges, you will need two Loggers. Remember that you get one in the Starter Kit.

There are three types of Logger available

Temperature only

Our most popular logger and, most likely, the one you will need.

These loggers have an internal temperature sensor so they sit inside your fridge or freezer.

Clever Logger CLX-01 Temperature Logger with External Probe


How many Gateways do you need?

There’s a limit to how far the Loggers can be from the Gateway and still communicate, so if your Loggers will be a long way apart (e.g. in separate rooms), you will need more than one Gateway.

If you’re not sure how many you will need, give us a call.


The Clever Logger Gateway sits near the fridge being monitored. Every few minutes, it picks up the temperatures from your Loggers and saves them to the internet.


Model: CLG-01

All Clever Logger systems come with at least 12 months of online data storage. After this, data can be archived.

Bulk pricing starts with orders of 10 or more single products, or 20 or more kits.

CleverLogger Replacement Battery Kit

Need a fresh battery?

We recommend that you change the battery in your Loggers every 12 months.

The CR 2450 battery is readily available but, to make life easy, we can send you a kit that contains a quality battery, an instruction card and a handy mini screwdriver. The kit also contains a replacement decal for your logger.

Shipping is included in the price.


What is a Logger?

Loggers record the temperature

The Logger uses an internal sensor or external probe to measure temperature. It saves these temperatures readings to its memory.

Loggers transmit the temperature

Every few minutes, the Logger sends its readings to the Gateway, which saves it on the internet.

The loggers have replaceable batteries that will last 10-12 months.

What is a Gateway?

Gateways talk to Loggers

The Gateway receives the temperature readings from the Loggers. A single Gateway can talk to many Loggers, as long as they are in range.

Gateways are connected to the internet

The Gateway is the link between the Logger and the internet, allowing your data to be saved to your account.

Gateways can connect to the internet with an Ethernet cable, or using wi-fi
