Home Assistant Yellow grows with you.

A home is not static. As we grow as a person or expand our family, our homes evolve. What we buy today, should work tomorrow. With Home Assistant Yellow we have created a system that can be upgraded so it can keep up as you grow.

At the heart of Home Assistant Yellow is the Raspberry Pi Compute Module 4. This plugs into the Home Assistant Yellow board and provides the brains. You can upgrade to a more powerful version of the Compute Module 4 at any time.

Home Assistant Yellow includes the latest and greatest Zigbee radio chip from Silicon Labs to communicate with smart devices in your home. The chip is forward-compatible with the upcoming Matter smart home connectivity standard, in which Silicon Labs is heavily involved. Home Assistant Yellow will be compatible with Matter as soon as the Silicon Labs Matter SDK is released.

Home Assistant Yellow also contains an M.2 extension port. This allows you to easily plug in an NVMe SSD drive to extend the available space.
