The Secure Liberty 100 smart meter is a pretty neat piece of kit. It has a communication hub to display your home’s dual fuel or single energy use. It offers a range of handy features, and a future-proof design. 

Although this smart meter was one of the first generation SMETS1 meters to be installed, all of them are now being remotely upgraded to work with all suppliers. Further remote firmware upgrades can update the features and functionality on the meter and communications hub, should it be necessary. The Secure Liberty 100 modules can also be replaced, to ensure your smart meter is always up to date.

  • It’s simple to install: As well as being future-proof, thanks to its remote upgrades, the registration and pairing process for the Secure Liberty 100 is straightforward.

Secure Liberty 100 smart meter manual

The Secure Liberty 100 smart meter keypad has a few different displays, which you can view by selecting the numbered buttons on the keypad. You can find a detailed explanation of the Secure Liberty 100/110 keypad functions here, but as a quick breakdown, the button displays include:

  1. Cost of consumption by day: what your energy usage is costing you on a daily basis
  2. Cost of consumption by week: your energy usage costs on a weekly basis 
  3. Cost of consumption by month: the cost of your energy usage on a monthly basis
  4. Historic data on cost of consumption and units: how much energy you have used and what it has cost you in the past

When it comes to how to read a Secure Liberty 100 meter though, it’s the button labelled 6 on your keypad that you’ll need to use. You can find out more on how to check a meter reading on a Secure Liberty 100 below. 

As well as the different numbered buttons, you’ll also see a blue A and red B button on the keypad. The A button is for prepayment customers, and has multiple functions. It activates vend mode, which lets you manually add credit to your smart meter. It can also be used to start the reconnection process (to get your supply reconnected), or enable Emergency Credit, which gives you extra credit to make sure your energy supply isn’t stopped. 

The B button can be used to activate auto scroll display, mute the alarm, or confirm supply reconnection, amongst other functions. You can find more details in your user manual.

How to read a Secure Liberty 100 meter

When it comes to taking a Secure Liberty 100 meter reading, you’ll need to select the button labelled 6 on the keypad. You’ll see the following information:

  • Your tariff name
  • Daily standing charge
  • Active rate register(s)
  • Consumption and cost per unit recorded

All you need to do is press the 6 button until you see IMP R01 on the display. This will be your R1 reading, which is your day reading. If you are on an Economy 7 electricity tariff, you can click the button again to see IMP R02, which signifies your R2 reading – or night reading. 

If you wish to take a note of these meter readings, you can write them down, ignoring any numbers after the decimal point. Remember though that with the Wide Area Network (WAN) and Home Area Network (HAN) features, the Secure Liberty 100 smart meter can securely send your energy use data to your supplier for you, without you having to lift a finger!
