The Journey Continues!

by Stefan A

What a ride! After six weeks, the campaign has concluded! Thank you so much for believing in Home Assistant Yellow!

We just received the next round of prototypes from our manufacturing partner. The PCB revision 1.0 is feature complete: compared to previous prototypes, we added LEDs, mitigated issues we found during EMI tests, and replaced some parts. At one point, we hoped this would be the production variant, hence we bumped the version to 1.0. Unfortunately part shortages require us to redesign some circuits again, so we can use parts which are actually available. Never call something 1.0 too soon! This redesign was already foreseen at the campaign launch, so it won’t affect our delivery schedule.

Home Assistant Yellow PCB 1.0

Along with the new PCB, we also received the first prototypes of the case (also known as test shots in injection moulding speak) from our manufacturer. The parts have been made with the injection mould tool we ordered a couple of weeks back and will be used for mass manufacturing. At this stage, it lacks surface finishing (note that the frosting on the inside is not done yet). Also the outside is not perfectly polished yet. But it is already looking really good!

Enclosure prototype without surface finish

We also need to iron out some details — if you look closely, the inside corners are not perfectly round. This is likely caused by shrinkage during cooling. We might need some tool changes or adjustments of moulding parameters.

With the campaign concluded, our next steps will be to source all remaining components. This phase will be crucial since on-time production and delivery can only happen if we source all the components. We already ordered some critical parts, and continued working on securing parts during the campaign. We should be able to source the remaining parts within the next months, but nothing is certain in the current chip shortage situation. Fingers crossed!

Talk to you soon!

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.


$119

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.


$109

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.


$22

12 VDC 24 W International Wall Mount AC Adapter

From the Crowd Supply Basics project.

In case you want an extra power supply.
