If your property is in mainland Europe you will need a UK to EU plug adapters for each of the smart plugs that we ship with the system. This is because as we have not officially released in the EU yet.
The Heat Genius App also uses weather data to predict when to bring the rooms on depending on the outside temperature. Unfortunately this will not work outside the UK but you can set a manual warm up period for each room with little effect on the main functionality of the system.
