[UPDATE 2015 12 13]
How about if you could control your entire home temperature and hot water/central heating etc etc, through your smartphone over the internet ?
You are going to think that this is a dangerous IoT (Internet of Thing) that exposes your privacy to unknown attackers and your smart home is going to be under the control of an evil company.
What if I could tell you, that you can build your own smart controller with open-design/open hardware & free software that costs about €100 ?
Crazy, right ?
Actually there is a project that does exactly all the above and much more and it’s based on a Raspberry Pi.
Let me introduce you to HestiaPi .
The name comes from the greek word: εστία and everything you need to start with, have already been published by the core developer on their site.
If you are curious on the project, visit hackerspace.gr and be part of this amazing project.
