Modern technologies allow any home to become smart in order to increase the level of comfort and safety, as well as save resources. You can create a Smart Home system not only in a new house. Many sensors and actuators can be easily integrated into apartments located in old buildings.
You can configure the Smart Home Installation so that it automatically opens the curtains in the morning, turns on the light on a voice command, and sends an alert to your smartphone if water suddenly leaks in the bathroom. You need to select specific sets of devices based on your goal.

Tips for creating a smart home
Treat the creation of a smart home as a project. Decide in advance what you want to get from it. If you don’t know how to answer this question unequivocally, start with the simplest one ― smart lighting.
A smart home is a scalable project. There is no need to buy many devices at once and spend much time connecting and configuring them. You can buy one sensor of different types, one smart switch, one smart outlet ― and only then purchase additional devices.
You need to learn how to use your smart home. Create simpler scenarios first, and only then move on to more complex ones. If you want to master all the functions faster, you may need the help of experts.
Try to choose smart devices of the same brand. And make sure that the sensors, actuators and controllers are compatible with each other.
Avoid duplication of functions. For example, if smart bulbs are used in your lighting devices, smart switches may not be used. And vice versa: if the house is equipped with smart switches, ordinary light bulbs can be installed in the lighting devices.

Be prepared for the fact that your smart home requires configuration and debugging, and this takes some time. And you’ll have to get used to it.
Creating Home Automation Installation is somewhat like a repair. Therefore, it is advisable to imagine in advance what you are ready to stop at, so that the creation of your Smart Home does not turn into an end in itself and does not require too much money and time.
Smart home is a system that needs a thoughtful design approach. Decide what functions it should perform, install the necessary devices ― and your home will become safer, and its comfort level will noticeably increase.
