Home automation, also known as smart home technology, allows users to control and automate various systems in their home such as lighting, climate control, entertainment, and appliances. A home automation system connects controlled devices to a central hub that can be controlled through wall mounts, mobile apps, tablets or the web. Setting up a basic smart home requires components like Arduino, NodeMCU, breadboards, wires and a smart assistant for voice control. However, a lack of technical standards and fragmentation between platforms can make developing consistent applications difficult. Security is also a concern as older and cheaper devices may not receive important software patches.

2. What is Home Automation?
Home automation or domotics is building automation for a home, called
a smart home or smart house. A home automation system will control
lighting, climate, entertainment systems, and appliances. It may also
include home security such as access control and alarm systems. When
connected with the Internet, home devices are an important constituent of
the Internet of Things.
A home automation system typically connects controlled devices to a
central hub or "gateway". The user interface for control of the system uses
either wall-mounted terminals, tablet or desktop computers, a mobile
phone application, or a Web interface, that may also be accessible off-site
through the Internet.

10. Criticism and controversies
Home automation suffers from platform fragmentation and lack
of technical standards a situation where the variety of home
automation devices, in terms of both hardware variations and
differences in the software running on them, makes the task of
developing applications that work consistently between different
inconsistent technology ecosystems hard. Customers may hesitate
to bet their IoT future on proprietary software or hardware devices
that use proprietary protocols that may fade or become difficult to
customize and interconnect.
The nature of home automation devices can also be a problem for
security, since patches to bugs found in the core operating system
often do not reach users of older and lower-price devices. One set
of researchers say that the failure of vendors to support older
devices with patches and updates leaves more than 87% of active
devices vulnerable.
