Home Assistant Yellow Kit

Description

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 – we previously stocked a version with a CM4 included, however as we now stock a range of CM4 boards, we’ve moved over to the kit versions to give you flexibility on memory and eMMC storage to fit your needs.

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

This version includes everything you need to create your Home Assistant Yellow, just without a CM4.

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 4and 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 CM4.

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 4. 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!We also stock the Home Assistant Green!
