Always at the right temperature with SmartGeo™


The 4iE can control your heating automatically and reduces your heating usage by up to 25%.

It works by using the location services built into smartphones, as well as learning your routines and the most efficient settings for your home.

So your heating is always at the right temperature, effortlessly. Your home is automatically warm as you arrive, and running efficiently when you’re away. Just like magic.

How SmartGeo compares to learning thermostats

Occupancy sensing systems detect when you’re home and learn your habits to create a predicted heating schedule. Which is great if you stick to the same rigid routine every day, but we know family life doesn’t stick to a schedule. These systems activate the heating when they think you’re going to be home and turn it down when they see that you’re not. If, like us, you can’t always keep to the predicted schedule, these systems can’t keep up and you’ll get home to a cold house or be wasting energy when you’re out.

SmartGeo also learns your routines, but critically, it combines this with the location services built into smartphones to know when you’re are heading back, heading out or just hanging around, even if it is not planned, so the heating is always at the right temperature. It’s comfortable as you walk through the door and running efficiently whenever you’re away.

How SmartGeo compares to standard geo-fencing thermostats

A standard geo-fencing thermostat will use the location services built into your phone to set a temperature based on how far away you are from home. The closer you are to home, the warmer the house. However, if you’re likely to be out for longer periods, like at work and would normally have turned the heating right down or off, these systems can potentially cost you more money by keeping your heating at a warmer temperature because they don’t take into account how long you’re likely to be out for, just how far from home you are and how long it will take you to get back.

SmartGeo learns your schedule and combines this with how far from home you are to set much lower, more efficient temperatures when you are likely to be out for longer, even if you are less than an hour away, for instance at the office.


Always on the best tariff with EasySwitch™

The 4iE works in the background to find the best energy deals.

EasySwitch searches the market for better energy tariffs, recommends the best deals, and makes it easy to switch.

Saving you on average £210 according to government figures.

EasySwitch can even be set to switch you on to the best tariff automatically, so you’re always getting the best deal, effortlessly.

How EasySwitch saves money every year

Over the past 4 years, UK households have paid £8.5bn too much for their energy. This is because when you sign up with an energy supplier, you will get their best tariff for the first twelve months just to get you on board. After that initial contract period is up, you are automatically moved to their standard rate. EasySwitch works in the background to keep you on the lowest tariff every year. Saving you on average £210.

Effortlessly.

Never come home to a cold house, or overpay on your energy bills again.

The 4iE doesn’t need programming and connects to your WiFi easily, with simple set-up and installation just like a traditional thermostat.

The large full colour touchscreen is easy to use and the MyHeating app is designed so any adjustments you do want to make to the temperature are quick and simple.
