Z-Wave and Rename

by Paulus S

Today we are announcing the rename to Home Assistant Yellow. It will stay the same product we announced as Home Assistant Amber, it’s just a new name.

A couple of weeks back Lewis from Everything Smart Home asked me if Aeotec’s Z-Pi 7 would work with Home Assistant Yellow. We have a subset of the GPIO pins available on the J11 header, which offers plenty of 3.3 V power and a UART directly connected to the Compute Module 4. Electronically, this is all what is required to make the Z-Pi 7 work.

We received two Z-Pi 7 from our friends at Aeotec and can confirm: Z-Pi 7 works with Home Assistant Yellow and the Z-Wave JS Add-on and Integration. It also fits into the case which provides an easy and clean way to extend Home Assistant Yellow with Z-Wave support.

We haven’t measured or compared RF performance yet. The orientation of the antenna might not be quite ideal, but keep in mind that Z-Wave forms a mesh-network. Z-Wave also uses a different frequency spectrum than the onboard Zigbee radio, hence interference should be minimal.

The Aeotec Z-Pi 7 comes with the latest 700-series chipset from Silicon Labs. It has a higher transmit and receive sensitivity than the Z-Stick Gen5 or Gen5+.

We are currently still in the process of securing components. One of the critical parts is the Silicon Labs MGM210P wireless module. We had received a shipping date previously but it turned out not to be a guaranteed date. We have not received a confirmed delivery date since then. As we are part of the IoT Accelerator, we remain cautiously optimistic that we can start deliver Home Assistant Yellow in the second quarter 2022.

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. All you need to get started is to plug in the power supply and the Ethernet cable, both of which are included. This variant does not have Power-over-Ethernet.


Yellow Kit with Power-over-Ethernet

The Home Assistant Yellow mainboard that comes with this kit supports Power-over-Ethernet (PoE). The kit does not include a power supply, though it is safe to operate it with both PoE and a 12 VDC power supply plugged in at the same time, in which case power will be drawn from the 12 VDC supply and not PoE. Custom enclosure, custom heat sink, and Ethernet cable included. You must provide your own Raspberry Pi Compute Module 4 and install Home Assistant on it.


Yellow Kit with Power Supply

Some assembly required! This kit includes everything in the flagship version except the Raspberry Pi Compute Module 4. This option allows you to pick the compute module with the memory and eMMC storage to fit your needs. You will need to install Home Assistant on the compute module you provide. Custom enclosure, custom heat sink, and Ethernet cable included. This version comes with a power supply, but does not support Power-over-Ethernet.
