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 Smart home systems such as BEMS and the more recent KNX have been on the market for years. Nevertheless except that require re-wiring automation throughout the home, and are particularly expensive. 
Their promise that they will pay you back the cost of the initial installation in the long run may be correct but as we said times are tough and the possibility of an "investment" in the economy of the house is a deterrent. In today's article we will look at some ways to make your home a little smarter without spending a lot money.
The following solutions they don't offer the ability to control your home from your smartphone, 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 room and turn them off when you're out, then think seriously to buy a latch with a built-in motion sensor. With about 8 euros you can place it in mono-sized areas such as a bathroom, a storage room, bedroom, etc. You can also set how long you want the light to stay on after you leave the room.
4. Window and door sensors
An alarm system is always an expensive affair. It requires wiring, i.e. digging and digging, and additional expensive machinery. But you can know when someone comes or leaves the house with a cheap sensor door. These machines are autonomous, cost 2 euros and emit a buzzing noise, similar to what you hear in stores.
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.
