Welcome to your new Trio.
The Trio shows energy use for electricity and gas smart meters and will have been configured to work with the meters you have installed, which may be electricity, gas or both.
In this document you'll find everything you need to quickly and simply set up and start using your Display. You'll also find out more information about how the Display works, how it can help you and how you can identify ways to save energy (and money).
What's in the box?
Your Trio package contains the following items:
Powering the Display
Your Trio Display can be powered using the supplied power supply or for short periods with 3 x AAA (R03, LR03) non-rechargeable batteries.

It is not recommended to use batteries for a prolonged period once the batteries are flat, they should be removed from the Display.
To replace batteries, slide the stand downwards and then pull it away. Insert the batteries, as marked on the inside case. Re-attach the stand and the Display will show the battery symbol at the top of the screen.
Do not use rechargeable batteries in this Display. To prolong the battery life, the display is designed to hibernate after five minutes of inactivity.
Press any button to wake the Display.
Overview of your new Trio
See what you're using
Your Trio Display makes your electricity and gas consumption visible, taking the guesswork out of understanding how much your home uses - both right now and historically.
What is a kWh?
Electrical and gas energy consumption is measured in kWh (kilowatt hours) - traditionally known as 'units'.As items within the home consume energy during the day, the kWh total increases.
A kW (or kilowatt) is the rate at which energy is being consumed, so using 1.5kW for 1 hour would result in 1.5kWh of energy consumed.
It's about now...
In the same way your car shows how fast your car is travelling, the electricity speedometer on the left of the Home screen shows how much electricity your home is consuming now. Similarly, the flame shows you how much gas has been consumed within the past 30 minutes.
The electricity speedometer is updated every few seconds and the gas flame every 30 minutes. To make it even easier to understand the hourly rates of consumption can show the rate of consumption in cost (£) and energy or power (kW).
For example, if the Display says £0.15 for the rate of electricity consumption, then this means that if the rate remained the same it would cost 15p for the next hour.
Less is more
The lower the hourly rate of consumption, the less it will cost and the more you can save. A typical medium sized house will use approximately 3100 kilowatt hours of electricity per year*, or approximately 5p per hour.
1 Watt of electricity running 24 hours a day costs around £1.30 a year. Therefore at bedtime, if your Display is showing approximately 200 Watts, this will cost approximately £260 a year. This is approximately 40% of average electricity bill. Reducing this by 70W, would save over £90.
The gas flame should be off when your boiler and cooker have not been used for 30 minutes.

How can I use less?
Look for appliances around the home that are not always being used and can be switched off.
Often it's items such as a games console, sound system or even a clock radio in the spare room. Experiment with switching appliances off and see what affect that has on the speedometer.
Other ways to save include having less water in the kettle (only boil what you intend to use), lowering the temperature on the washing machine, or turn down your thermostat by 1 ºC - this could save £75 per year*.

What is normal?
Don't worry if now and again the usage is high - this can be normal.
Your electricity usage varies as things are switched on and off in your house. Electricity usage can be low (green), medium (amber) or high (red). Boiling a kettle for example will mean for a short period of time your house usage will be medium (amber); in the evening or morning time it might also be medium (orange)- this is perfectly normal.
If you have electric or storage heating, then it is possible to see high usage (red) when the heating is being used. During other periods the usage should be low (green), especially when you are heading to bed.
Depending on your smart meter, the maximum rate of consumption the dial can show can be adjusted. See 'Advanced'
Meter connection
Each time the Display is turned on it will show Connecting... for up to 5 minutes while the Display connects to the smart meter(s) in your home.
If the screen shows Lost Network, then you may need to move the Display closer to your smart meter(s) to re-establish the connection.
Connection established
Once your Display has successfully established a connection to your smart meter(s), your Trio will show the current consumption for electricity and recent gas usage.
If your Display loses connection to the smart meter(s), then it will show the alert above. Try moving the Trio closer to the smart meter(s) to re-connect.
Overview
The Home screen is broken down into three tabs- Now, Today and Prepay.
When your Trio is powered on, it will automatically show the Home screen once connected to the smart meter(s).
You can also, at any time, press on the Display to return to the Home screen.
Touch Now, Today or Prepay (when in prepayment mode) to switch between the tabs. The Prepay tab is only shown when one of the meters is in Prepay mode.
When you next return to the Home screen from other screens, the previously selected tab will automatically be shown.
The banner bar allows you to check the smart meter(s) signal strength , battery status, if on batteries
, and alert you to problems
.
Meter network signal strength OK (normal condition for the Display).
Meter network lost and showing the alert symbol (the alert symbol can be shown for multiple reasons- see System Status for more details).
The message icon appears when the Display has any new messages (Home screen only). When on batteries the battery symbol is also shown (in this case battery low).
Now screen
The Now screen is divided in half, with the left side showing Electricity consumption now and the right showing Gas consumption.
Depending on your smart meter configuration, only the available energy types will be shown - the gas flame will not be shown if you do not have a gas smart meter, for example.
This is the default screen shown when the Display has started up.
To toggle between cost and kW press the toggle button ().
Electricity (left)
The dial on the left (only available when you have an electricity smart meter) shows the current rate of electricity energy use for your home.
As your home uses more or less electricity, the dial will move up and down. The dial is divided into three zones - green, amber and red.
As the dial moves between the zones, the colour of the LED on the front of the display will change to match.
This means at a distance, you can quickly see if your home is using a little or a lot of electricity. The current rate of consumption can be shown in cost as £/hr (default) or energy as kW.
To toggle between cost and kW press the toggle button ().
Gas (right)
The gas flame indicates the recent consumption rate of gas for the home (where available). The gas usage consumption readings are updated every half an hour.
As more gas is consumed, the blue flame will increase in size.
This means at a distance, you can quickly see if your home is using a little or a lot of gas.
Due to readings being taken every half an hour, the flame shows recent gas consumption and may not show when gas is no longer being consumed.
Touch the flame to go to Gas usage history.
Today screen
The Today screen shows the total cost or consumption so far today for Electricity and Gas.
If you have set a budget for each fuel type (see Settings), then the Display will show the percentage of budget used so far today, and the associated cost. The percentage used is represented as a number and as a coloured ring around the percentage.
For both fuels, the budget ring is shown in green if less than 90% of today's budget, amber if greater than 90% but less than 100%, and red if the budget has been exceeded for today, and by how much (up to 100% over budget).
To toggle between cost and kW press the toggle button ().
The budget can be set within the Menu > Settings > Budget menu.
Prepayment screen
This screen is only shown if one or more meters are in prepayment mode.
The Prepay screen shows the current available credit for prepayment meters. Electricity is on the left and Gas on the right.
The outstanding balance is displayed for each fuel in prepayment mode, along with how many days predicted before requiring a top-up. The outer ring changes colour to indicate how many days are remaining:
When you first set up your Trio, it will take a couple of days to gather enough information to sensibly calculate how many days your balance will last).
If friendly credit or emergency credit is available from the meter, then this will be shown on the prepayment screen, examples below; the same applies to your gas.
The Trio is capable of notifying you when the prepayment balance is low, change the alert setting (Settings > Prepay > Low credit alert) to be notified. Similarly, when Emergency credit becomes available, a pop-up will be shown to alert you. (regardless of the screen you are on).
Emergency credit can also be activated from the prepay menu.
Single fuel mode (credit customers only)
When only one fuel is supplied, and the meter is in credit mode, the home screen will be show consumption now, and the energy used for today. The example below is for electricity, gas will adopt a similar approach.
Touching the cost or kW (kWh), will switch between cost view and consumption view.
To toggle between cost and kW press the toggle button ().
Single fuel mode (prepayment customers only)
When only one fuel is supplied, and the meter is prepayment mode, the home screen will show consumption now, and prepayment information.
System status
This screen shows if there are any problems with your smart meter system.
Should there be a problem with any area this will be shown as red. Touch any of the icons to view more information on the different parts of the smart metering system, and press the toggle button () to see further information.
Press the button to return to the Home screen.
The icons show the following:
![]() | Status of the electricity meter (where fitted) |
![]() | Status of the gas meter (where fitted) |
![]() | Signal status between the display and the smart meter(s) |
![]() | This display (always green) |
![]() | Signal status to the local WiFi network |
![]() | Connection status to the Cloud service. WiFi and a cloud connection are only available if the Trio is fitted with a WiFi module. |
Electricity usage history
The Electricity usage history has four tabs, from left to right-Hours, Days, Weeks and Months. Use the left and right arrow keys to move between the tabs.
Each of the screens is designed in a similar manner. The left side of the screen shows a bar graph of electricity usage for the period in either kilowatt hours (kWh) or cost (£). For example for the Hours view, bars represent hours, and Days view the bars represent days. The cost or usage for the highest hourly period is also shown.
The right side of screen shows the total cost (£) or total usage (kilowatt hours) for the period, and when showing cost, if a budget has been set then the budget for that period. Electricity usage history can be found through the main menu (Menu > Usage history > Electricity history).
Hours tab
The screen initially shows the current electricity usage for today in cost (£), divided in to the 24 hours of the day. Each bar represents one-hour period and is shown in green.
The hour with the highest consumption or cost is shown a value to the right of the bar.
To change from cost to kWh press the toggle button ().
The total cost for today is shown inclusive of any daily standing charge. (if your tariff has a standing charge). This means at midnight the total may be greater than £0.00, even if no electricity has been used. The bars exclude any daily standing charge (if your tariff has a standing charge). Note the Hours tab does not show today's budget.
Days tab
The Days tab shows electricity usage for today and the previous eight days. The bars include any daily standing charge. (if your tariff has a standing charge). If a budget has been set (see Settings > Budget), then the bars will indicate if you are over budget for the day (by a red/grey hatched area).
Weeks tab
This shows this week and the previous five weeks in the same way as the Days tab. The bars include any daily standing charge. (if your tariff has a standing charge).
Months tab
The final view is the Year tab which shows this month and the previous 13 months of usage or cost. As with the Days and Weeks tabs, you can see months that were above and below the budget. The bars include any daily standing charge. (if your tariff has a standing charge).
Gas usage history
The same historical views are available for gas consumption.
