How far away can my Smart Gateway* be from my meters?

Your Smart Gateway should be able to work up to 15 metres away from your Smart meters. However, its effectiveness depends on what lies in between your meters and the Smart Gateway – for example, the number and thickness of walls.

*We offered Smart Gateways to our energy customers from 23rd April to 7th September 2015, but this offer is no longer available.

Your Smart electricity meter is the main meter that communicates with your Smart Gateway. It collates the information from your Smart gas meter with data about your electricity use and transmits them both to the Smart Gateway. It does this through a home area network (HAN), a secure network that works in the same way as other wireless systems in your home.

The HAN uses a network called Zigbee, which is very similar to Wi-fi and Bluetooth. It has a range of 15 metres (imagine a bubble around the electricity meter), so that’s why your Smart electricity meter and Smart Gateway should be within 15 meters of each other, with as few walls as possible between them.

How much does it cost to run a Smart Gateway?

A Smart Gateway consumes an average of 2.5W of power. This is equivalent to 21.9kWh over the course of a year. At a unit rate of 12.45p/kWh (Our Better Energy Fixed tariff price as of 10/09/2015) this equates to £2.73 a year.

… and how much would an IHD cost me to run?

An IHD consumes an average of 0.6W of power. This is equivalent to 5.26kWh over the course of a year. At a unit rate of 12.45p/kWh (Our Better Energy Fixed tariff price as of 10/09/2015) this equates to £0.65 a year.

What will happen to my IHD or Smart Gateway if I leave Ovo?

If you have an IHD, it will still work in the same way once you’ve switched to a new supplier, so it will still be able to give you accurate figures for your gas and electricity use. However, unless your new supplier uses exactly the same make and model of IHD, they won’t be able to update it. So, for example, they won’t be able to change your unit rates or the fact that your IHD is branded ‘OVO’.

If you have a Smart Gateway, it won’t work once you’ve left OVO as it’s linked to My OVO and can’t be reprogrammed to work with your new supplier’s systems.
