How do I automate my home using a Raspberry Pi?

You can use a Raspberry Pi for a low-cost home automation setup. Some of the best home automation software are open-source and free so you can use them to program it to sense and control smart devices around your house.

You'll just need to connect compatible devices and make sure that your Raspberry Pi can talk to them with a Zigbee or Z-Wave stick.

The Best Open Source Home Automation Software

Alright, let's jump right into the list of great open source home automation platforms.

Home Assistant

I consider Home Assistant the most popular open-source home automation software. It’s platform runs on Python 3 and is most commonly installed on a Raspberry Pi for a low-cost setup. Since its start in 2013, Home Assistant has become a favorite among developers and DIYers since they could easily customize their own features by writing their own Python scripts.  

Home Assistant is a stand-alone system and does not depend on third-party cloud services. Support for third-party devices and services is handled in their community forum.

Standout Features

What’s nice about Home Assistant is that it supports many third-party components like communication protocols, automation platforms, voice assistants, and many other plugins. The Home Assistant software is totally FREE and has no subscription fees. They also have a large community of admins and DIYers who would happily respond to your queries.

Pytomation is an open source home automation system developed using the Python language. It’s main function is to automate smart devices in homes but is capable of doing more functions like remote control.

Reminds me of our Amazon Dash hack to make a home automation remote!

The primary development is in Linux, but it can be used on any computer using Python. The most popular computer being used with the Pytomation software is the Raspberry Pi single-board computers. Basically, a Pytomation system is a stand-alone controller, like a microcontroller, that would automate actuator or device actions based on sensor readings. But since the controller is a computer, it is also capable of being managed and controlled via mobile applications and web servers.

Pytomation was first released in 2012. Since then, they have been releasing latest software updates with support for newer third-party devices.

Standout Features

Affordability is one of the most outstanding feature of the Pytomation automation system since it runs on open-source hardware and software. Only a single-board computer, its open-source software, and a smart device of your choice is needed to start automating your home.

Another feature of the Pytomation is that it’s not dependent on the cloud and other third-party web services. It can be run and managed locally.

OpenRemote is an Internet-of-Things (IoT) platform that promotes smart homes and cities. They started in 2009 with the end-goal of bringing a universal automation platform for smart devices to the market. Back then, offline-devices couldn’t connected to the internet using hardware WiFi adapters that use standard protocols. As the IoT technology gained popularity, many companies developed their own smart devices with their own proprietary protocols also. OpenRemote’s main challenge was providing all the interface supports of third-party products and services so it would be compatible with their universal controller.

OpenRemote tries to support many proprietary protocols of different brands. One could just simply add and remove a type of smart device on their dashboard and save the configurations for an easy and customized setup. As long as your devices and your controller, say a tablet or mobile phone, are connected to a WiFi network, you can easily manage your smart devices remotely with just a few tap.

Smart cities and big data is also one area that OpenRemote focuses on, aside from home automation. They integrate data from public spaces like traffic, automated lighting, pollution, emergency, and many others in order to enhance the quality of living.

Standout Features

OpenRemote allows any smart device to be connected, controlled, and automated. Their OpenRemote Designer software enables users to modify their own custom setup according to what smart devices they have at home or at their office. All you’ll need to do is to add your devices and their corresponding functions on the graphical interface. Once it’s done, you can now monitor and control everything via your smartphone, PC, or tablet.

OpenRemote don’t only offer products. Aside from having an online community that you could ask help from, they also have consulting partners in some parts of the world who could help you design your own home automation system and choose the best certified products for you.

Domogik - No Longer Active!

Domogik was an open-source home automation software (GPLv3) that featured voice control, and open API, and an HTML front-end to control lights, fans, and whatever else you wanted to control. The integration with OpenRemote to control devices was a big enabler for the software. Domogik was active until 2017 but is no longer under active development.
