DIY smart home projects are becoming increasingly popular. Everything from complete security systems to lighting is unified through the Internet of Things (IoT). What used to be separate systems can now all be controlled from your smartphone. Since this is new technology, some aspects of home automation are expensive. That said, if you have a DIY attitude and some inexpensive components, you can create a smart home for a fraction of the expense.

What Is a Smart Home?

A smart home incorporates progressive automation systems to provide its occupants with complex monitoring and control over the home’s functions. For instance, a smart home might allow you to remotely control temperature, lighting, door and window operations, security and multi-media, among other functions. A smart home uses automation technology to provide occupants with smart feedback by monitoring several things in the home. For instance, a smart home may have a refrigerator that keeps a record of its contents, makes menu suggestions, and orders replacement foods when necessary.


Advantages of DIY Smart Home Projects

Thanks to smart security cameras, we can see what is happening in our homes even when we are not there. Now you can ensure that no unwanted guests invade your home while you and your family are away. Security cameras enhance you and your family’s safety.

Remote Temperature Control

Google Nest Thermostat - Smart Thermostat for Home - Programmable Wifi...
  • ENERGY STAR certified smart thermostat for home that helps you save energy and stay comfortable
  • The Nest Thermostat is designed to work without a C wire in most homes, but for some systems, including heating only, cooling only, zone controlled, and heat pump systems, youโ€™ll need a C wire or other compatible power accessory
  • Nest Thermostat turns itself down when you leave, so you donโ€™t waste energy heating or cooling an empty home

It is a commonplace occurrence to rush off to work without bothering to adjust the thermostat before we go. This means we come home to find our home is too cold or too hot. This is quiteย inconvenient as it often takes a lot of time for the temperature to become comfortable after adjusting the thermostat. With the right DIY smart home device, you can adjust the thermostat while you are still at work. This is also cost-effective as it saves energy.

Consider when you go on a business trip or vacation and have to give a key to a friend or neighbor so they can water your plants, care for your pets or pick up your mail while you are gone. Perhaps you worry that this person might lose the key, or worse, snoop through your things while you are away. There are smart home systems that can eliminate this worry. Instead of giving someone a key to your home, you can use an app on your smartphone to unlock your door and let them in at specific times. Through the use of security cams, you can monitor them while they are there.
