Home Assistant Yellow
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. Without the Raspberry Pi Compute Module 4.

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. Custom enclosure, custom heat sink, and Ethernet cable included. This kit does not include a power supply (because power comes from PoE).

Open hardware

We spend a lot of time and resources on fine-tuning our products. We want other people to be able to study our work and be able to make their own great smart home products. For this reason, we've released the schematics of Home Assistant Yellow as open-source. Explore the board and view the source.

Buying a Raspberry Pi Compute Module 4 (CM4)

If you bought the Home Assistant Yellow Kit, you need to bring your own Raspberry Pi Compute Module 4.

A chip shortage still impacts the availability of the CM4. Our recommendation is to use rpilocator. This website tracks the stock of official Raspberry Pi distributors. Follow them on Twitter and enable push notifications. You will be notified as soon as the bot tweets that products are in stock.

We recommend purchasing a Raspberry Pi Compute Module 4 with the following characteristics:

• Min. 2 GB of RAM.
• Min. 16 GB of eMMC flash space.
• If you opt for the CM4 Lite: as it does not have an eMMC module, you must use an NVMe SSD hard drive. Some users reported that following SSDs are not working on the Home Assistant Yellow.
