Looking for a new boiler, but as I have a long term illness which gets me hospitalised quite a bit It would be great if I could control my heating from my smartphone, as sometimes I have been taken in unexpectedly and heating left on, I have heard of hive, and nest who do something which would be great has anyone used these or is there something cheaper on the market that a diy person could fit, as I gather its just replacing your thermostat and linking it up to your broadband. Thanks in advance.
