The financial difficulties of our time require the financial management of our home, so that it consumes the fewer kilowatt-hours while at the same time offering comfort to its owner. In short, the modern home must be automated or if you want it to be a "smart house".
There are many ways to do it house you smart. The market has been running for years, smart home systems such as BEMS and the latest KNX. But besides requiring the re-installation of automation wiring throughout the house, it is also very expensive. 
Their promise that in the long run will depreciate the cost of the initial installation may be right, but as we have predicted the times are difficult and the possibility of an "investment" in the home economy is dissuasive. In our current article we will see some ways to make your home a little smarter without spending a lot of money.
The solutions below do not offer the ability to control your home from smartphone you, not even from the Internet. But, it can definitely make your life easier.
1. Wireless remote-controlled sockets
There are sockets on the market that can be controlled by your mobile phone but are considered too expensive. With only 10 euros you can find remote-controlled sockets that you can operate on / off via a remote control like your TV.
The range of the remote is usually the same as the one room. The only problem that you will encounter is their massive shell that covers the entire socket. However, if you can overlook this disadvantage and buy it, then you can turn on various electrical items without getting out of the couch.
2. Timers
If you want your lights to be switched on and off automatically at fixed times throughout the day then you need to buy a power timer. With prices starting from 3 Euros for engineers and from 8 Euros for electronics you can get a timer-plug.
What you can attach to it depends on your imagination. From the coffee shop to have you in the morning, before you wake up, coffee ready, to a random lamp program it will flash at will and confuse thieves that there is a presence of people in the house (while you will be taking your baths in some island).
3. Door with motion detector
If you are bothered by the constant process of turning on the lights every time you enter a roomeyeo and turn them off as soon as you go out, then seriously consider buying a shower with a built-in motion sensor. For around 8 euros you can place it in areas with single light, such as the bathroom, in a warehouse, in the bedroom, etc. In addition, you can set how long you want the light stay on after you leave the room.
4. Window and door sensors
An alarm system is always a precise case. It requires wiring, that is to say, dredges and meadows, and also expensive machinery. But you can know when someone comes or leaves the house with a cheap door sensor. These machines are stand-alone, cost 2 euros and emit a buzz noise, similar to what you hear in the shops.
You can also use them for windows to know if a window is open or not. There are glass breakage sensors, but you can also buy separately and such sensors. They are not as cheap (50 euros for a sensor), but one can cover an entire room with only one sensor.
