Home Assistant Yellow: the open-source home automation box!

The home automation sector is definitely in full swing this coming back to school. After Homey Bridge last week and Jeedom atlas wednesday, here comes Home Assistant Yellow, previously named Amber! Nabu Casa, the company behind the software, is launching a crowdfunding campaign with the aim of providing a ready-to-use box. Based on the Raspberry Pi CM4 module, this gateway aims to democratize the free and open source home automation system.

Home Assistant Yellow: a plug & play box?

Last year, Nabu Casa launched Home Assistant Blue, a limited edition box based on the Odroid N2 + nano-computer and intended to offer more powerful hardware than the traditional Raspberry Pi to users of open-source home automation software. Now abandoned, the project has changed from blue to yellow with the idea of ​​designing a system perfectly optimized for Home Assistant OS from scratch… And a Raspberry Pi!

It is indeed a Raspberry Pi Compute Module 4 (CM4) which will constitute the heart of the machine which will also integrate the very last Zigbee 3.0 module Mighty Gecko MGM210P from Silicon Labs currently supporting Openthread and very soon the news Matter home automation specification.

Home Assistant Yellow will also offer a Gigabit Ethernet port with PoE to power it, a M.2 port intended to receive an SSD in NVMe format or the Google Coral AI platform, 2 USB 2.0 type-A ports et 1 USB 2.0 type-C port (usable in UART mode for serial console access or in USB mode for recovery).

Everything will be housed in a plastic case rather compact translucent polycarbonate from 123 x 123 x 36 mm very aesthetic DIY, but the objective is above all to provide an efficient, scalable and totally open system ...

The Home Assistant Yellow home automation box is offered in crowdfunding priced at $ 149, or about 126 euros. The objective of $ 140 to start production should quickly be reached since 000% of the project is already funded thanks to the first 44 contributors. You have until 27 October 2021 to participate.

More open source than ever!

Home Assistant Yellow is open-source from A to Z, giving you full and unrestricted control of your home automation system. Operating locally, this home automation box does not depend on the Internet or a cloud, all your data being stored warm at home. Nabu Casa specifies that all the design resources will become available as the project progresses and that Home Assistant Yellow can very well be used with other software such as Jeedom or Raspberry Pi OS for example.

Over a thousand devices and integrations are compatible with Home Assistant OS, many of which are not supported by other popular platforms like Apple HomeKit, Samsung SmartThings or even Amazon Alexa and Google Home. You will find the complete list of devices on the Home Assistant official website.

Risk of shortage

Due to the global component shortage, Nabu Casa warns that Home Assistant Yellow is not immune to supply difficulties. Indeed, only 500 complete units and 2000 units of each variant of the Yellow kit could be ordered.

« The Raspberry Pi 4 compute module has been particularly difficult to find in bulk, although many CM4 variants are available in low quantities from various vendors. »Explains the company which invites the most impatient to order a variant without the module and to acquire it separately.
