What is Home Assistant?

Home Assistant acts as a brain for your home’s tech. It brings all device controls and monitoring into one place.

Open-source home automation software

Home Assistant is an open-source home automation software allowing for centralised control and monitoring of various home devices. This platform supports an extensive range of smart gadgets across different brands—from lights and security systems to heating solutions, EV charging and even dishwashers. You can adjust settings, check statuses, and automate tasks without needing separate apps for each device.

Its open-source nature encourages a vibrant community of developers and users to share insights, enhancing its capabilities continuously. It supports devices across different brands through local APIs and other connections such as Modbus for technical equipment including solar power and battery systems or Shelly EM for energy monitoring.

It’s compatible with hardware such as Raspberry Pi, known for its low power usage and strong community backing. Through this integration, users gain detailed insights into their household’s energy dynamics—optimising solar use and improving return on investments in renewable energy systems.

Benefits for Solar and Battery Installations

Home Assistant turns complex data into simple insights, making energy management and battery efficiency a breeze.

Consolidated monitoring for solar and battery systems

Home Assistant makes it easier to keep an eye on both solar and battery systems from one place. This tool gathers all the important information – like how much energy your solar panels are making or how full your batteries are – and shows it in a clear, easy-to-understand way. Users can see everything they need on their dashboard, whether on a web app or through browsers. You can even tailor the setup to meet your specific needs, from automating charging of your GivEnergy battery system to obtaining Agile Octopus’s next-day electricity rates.

Power flow cards within Home Assistant visually display the movement of electricity. They show how energy flows between the house, batteries, and solar panels in real-time. This feature helps users quickly understand what’s happening with their setup at any moment—whether storing energy efficiently during sunny periods or needing to draw from the grid due to low solar output.

Solar forecast automation for grid independence

Solar forecast automation uses the latest weather forecasts to predict how much solar energy your panels will produce. It then adjusts battery charging schedules to make sure you use more solar power and less from the grid. This smart feature helps your home stay as independent as possible from external power sources.

Recommended hardware for running Home Assistant


Home Assistant Yellow

  • This device is akin to a Raspberry Pi with a CM4, but it stands out with its custom hardware enhancements.
  • It comes equipped with built-in Zigbee and Thread radios, making it an all-encompassing choice for home automation.
  • For those in the UK, bringing a Yellow unit home costs around £250. The price reflects its advanced features and comprehensive connectivity options.
