Smart Home is an application that makes it easy to connect WiFi devices (arduino, esp 8266, raspberry, etc) to your phone or tablet so you can control your appliances or sensors anywhere in the world, or only from your local network.
In this way you can control the house lights, temperature and humidity, power consumption, air quality, IR remote controlled devices like HAVC, TV, air conditioners and so on, and set different parameters, for any of them.
The application does not use a web server to connect to, so you do not have to pay a monthly fee, or be addicted to a particular site.
Sensors can also be read from multiple sources, including external sources, for example:
If you do not own a weather station hardware, and you want to display weather condition you can just import sensors readings from web sites in XML, JSON or HTML format.
