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. Yellow Kit with power supply Some assembly required!

It came pre-assembled in a custom enclosure with a Raspberry Pi Compute Module 4 (CM4), a custom heat sink for silent operation, and with the Home Assistant Operating System pre-installed. *Although Home Assistant Yellow Standard is no longer manufactured, it will continue to receive the same support as the kit models. If you are looking for more of a plug-and-play experience, take a look at the Home Assistant Green. 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. 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. 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.

No. We previously offered a Home Assistant Yellow Standard model that came pre-assembled with a Raspberry Pi CM4, but this model is no longer manufactured. It is now recommended that if you want a more plug-and-play experience, you purchase a Home Assistant Green, as it requires no assembly and matches many of the capabilities of the Yellow, especially if you add a Home Assistant Connect ZBT-1 to give it Zigbee/Thread capability. What happened to Home Assistant Yellow Standard, and will it still be supported? The Home Assistant Yellow Standard was originally designed to be the beginner option in our product line, as it was pre-assembled and easier to get started with. In 2023, we launched the Home Assistant Green, which offered similar features, including easy setup, but at a lower price point. This led us to end the manufacture of the Home Assistant Yellow Standard and focus on Yellow Kit versions for those who enjoy assembling and customizing their own hardware. Rest assured, it will continue to receive the same support and software updates as the Yellow Kit variants.
