100+ Home Automation Ideas with Tutorials: from Simple to Amazing

No silly gimmicks. This collection of home automation ideas will actually make your home more enjoyable for you and your guests.

I’ve personally implemented many of the ideas in this list.

These all came from our DIY Home Automation project. Pictured above is a 3D Floorplan of our home. It is made interactive with Home Assistant.

As I was building the cabin, I found many of the home automation ideas to be silly and gimmicky. Many solutions end up being clunky and hard to use. For example, changing light scenes with a smartphone app seems fun at first. Until friends come over and turn off the light switch. Or you get tired of pulling out your phone from your pocket and unlocking it when you have an armload of groceries.

After many years of experimentation, I compiled this list of home automation ideas from the things that actually made the home more convenient to use.

About these Home Automation Ideas

Each idea has a difficulty level:

• Beginner home automation ideas:
  Use pre-built products (linked) and require little experience.
• Intermediate home automation ideas:
  Include tutorials and link to source-code for existing software on an Arduino/Raspberry Pi.
• Advanced home automation ideas:
  Bring your own creativity (knowledge of coding, electronics, etc. may be required).

I’ve tried to include links and tutorials wherever I can… but there’s a lot in this list! Leave a comment at the end if you’d like a deeper exploration into one of the topics.

I happen to use Home Assistant for all of my home automation ideas. It’s a popular open-source solution. It does not send your data to companies like Google and Apple. Some of the links below will reference Home Assistant in particular. All the ideas would translate to other home automation platforms.
