The foundation of your smart home needs to be local and private. Home Assistant Yellow is that foundation.

This is the Home Assistant Yellow Standard - the flagship version of Home Assistant Yellow, ready to go out of the box with a CM4 included! It comes pre-assembled in a custom enclosure with a Raspberry Pi Compute Module 4 (CM4) included and a custom heat sink for fanless, silent operation.

The CM4 is a version without wireless and has 2 GB RAM and 16 GB eMMC storage. Pre-installed with Home Assistant.

To get started, just plug in the included power supply and Ethernet cable. The cables are included in the box. This variant does not have Power-over-Ethernet. Home Assistant Yellow is Matter-ready, upgradeable, and extendable. You won't need anything else.

We also stock the Home Assistant Green!
