NABU CASA - Home Assistant Yellow Smart Home Kit (with PoE)

Our take on Home Automation

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

Home Assistant Yellow is Matter-ready, upgradable, and extendable. You won't need anything else.

This flagship version of Home Assistant Yellow is ready to go out of the box.

It comes pre-assembled in a custom enclosure with a Raspberry Pi Compute Module 4 (CM4) 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 power supply and the Ethernet cable. The cables are included in the box. This variant does not have Power-over-Ethernet.

Yellow Kit with Power-over-Ethernet

Some assembly required! This kit supports Power-over-Ethernet (PoE) but is otherwise almost the same as the flagship version. Custom enclosure, custom heat sink, and Ethernet cable included. Without the Raspberry Pi Compute Module 4.

Not included: You must provide your own Raspberry Pi Compute Module 4 and install Home Assistant on it. This allows you to pick the compute module with the memory and eMMC storage to fit your needs. This kit also does not include a power supply (because power comes from PoE). The router or switch must supply Power-over-Ethernet. Typically, PoE capable ports are labelled as such.
