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

We now stock two versions of the Home Assistant Yellow Kit - read on to find the right version for you.

These kit versions do not include a CM4 or CM5 - we previously stocked a version with a CM4 included, however as we now stock a range of CM4 and CM5 boards, we've moved over to the kit versions to give you flexibility on memory and eMMC storage to fit your needs.

Update! Home Assistant Yellow can now benefit from a 2x speed boost by installing a Compute Module 5, see the official word here, and also reported by Jeff Geerling!

Option 1: Home Assistant Yellow Kit (with power supply)

This version includes everything you need to create your Home Assistant Yellow, just without a Compute Module.

You get the carrier board, custom enclosure, power supply (with international heads - UK, USA, EU and AUS), heatsink, fixings, ethernet cable and a couple of HA stickers!

You will need add your own Compute Module 4 or 5 and you're ready to go. Naturally, some minor assembly is required.

Option 2: Home Assistant Yellow Kit (with Power-over-Ethernet)

This is the Power-over-Ethernet version of the Home Assistant Yellow Kit, meaning the carrier board supports PoE. use this version with your PoE-ready router, switch or PoE injector. Again, this is a kit version without a Compute Module.

You get the carrier board, custom enclosure, heatsink, fixings, ethernet cable and a couple of HA stickers!

You will need add your own Compute Module. This version does not come with a power supply as it is intended to be powered via PoE. Naturally, some minor assembly is required.

Home Assistant Yellow is Matter-ready, upgradeable, and extendable! Be sure to check out our dedicated Home Automation section for everything else you might need for your smart home project. We also stock the Home Assistant Green!

Home Assistant Yellow Kit Yellow Kit with PoE
Home Assistant Yellow Kit with PoE — Powerful, Compact, and Worth It The setup was easy overall, and I’m really pleased with the result. The CM5 instructions, particularly around heat sink installation, could be clearer — I’d suggest PiHut consider adding a link to their own guide or working with the Home Assistant team to update the wiki. That said, I got there in the end. If you’re a newbie like me, installing the OS might look daunting because of all the jargon — but honestly, just download the Windows installer and it’s done in no time. (Tip: if you can’t see the Pi from your PC, check that the jumper on the board is correctly set!) I went for the latest CM5 board with the CM5 heat sink and it fitted perfectly. Super happy with the purchase — it’s a powerful, compact bit of kit that makes a great smart home hub.

Home Assistant Yellow Kit Yellow Kit Standard
I recently ordered the Home Assistant Yellow Kit (Standard) from Pi Hut, and I couldn’t be happier with the experience. The shipping was incredibly fast, and the packaging was excellent—everything arrived well-protected and neatly arranged, which I really appreciated. As for the kit itself, it’s a fantastic piece of hardware for anyone serious about home automation. The build quality is solid, and the design is clean and compact. Setup was straightforward, and it integrates seamlessly with the Home Assistant ecosystem. I haven’t pushed it to its limits yet, but as a foundation for smart home projects, this kit feels future-proof and thoughtfully designed. Highlights: Blazing fast delivery and top-tier packaging from Pi Hut Great build quality and compact form factor Perfect for long-term Home Assistant setups Highly recommend both the product and Pi Hut’s service—zero complaints. 🤘

This is a great bit of kit to start building a Home Assistant setup. The integrated Zigbee makes it easy to start adding door sensors, switches and the like from a wide range of suppliers.
