Description ▼

Raspberry Pi CM5 is mostly available with some variants being pre-order.

What does each Kit includes (Feel free to reach out if you want to customize one of our Assembled kits)?

*For pre-assembled units, we thoroughly test them before shipping, up to the point where the system prompts for user creation. However, in certain instances, you might still encounter an issue where port 4357 is accessible via your device's IP address (e.g., 192.168.1.15:4357), but port 8123 remains unresponsive. We have collaborated with the Home Assistant team to investigate this, but neither we nor they have identified the underlying cause. While factory resets via OS reflashing typically resolve the issue, we have not been able to find a way to prevent this from happening. As Home Assistant is a free, open-source operating system, occasional failures may occur that require OS reinstallation. We strongly recommend familiarizing yourself with the OS installation process and maintaining regular backups of your data to minimize any potential disruptions.

*Assembled bundles might take 1-3 business days to ship as they need to be assembled and tested.

*Some customers have reported that while moving the Data Disk to an NVMe, the Home Assistant interface may display the NVMe size as "0". Despite this, the moving process still functions correctly. Even if the size remains "0" after the Data Disk has been moved, the "Disk Used Space %" will display accurately, reflecting the correct available space.

Alternatives to the Home Assistant Yellow:

Home Assistant Yellow integrates 1,000+ different devices and services, allowing you to create powerful automations and get insight into your energy usage. All from an easy-to-use interface that runs 100% locally without anything in the cloud.

Home Assistant Yellow grows with you.

A home is not static. As we grow as a person or expand our family, our homes evolve. What we buy today, should work tomorrow. With Home Assistant Yellow we have created a system that can be upgraded so it can keep up as you grow.

At the heart of Home Assistant Yellow is the Raspberry Pi Compute Module 4. This plugs into the Home Assistant Yellow board and provides the brains. You can upgrade to a more powerful version of the Compute Module 4 at any time.

Home Assistant Yellow includes the latest and greatest Zigbee radio chip from Silicon Labs to communicate with smart devices in your home. The chip is forward-compatible with the upcoming Matter smart home connectivity standard, in which Silicon Labs is heavily involved. Home Assistant Yellow will be compatible with Matter as soon as the Silicon Labs Matter SDK is released.

Home Assistant Yellow also contains an M.2 extension port. This allows you to easily plug in an NVMe SSD drive to extend the available space.

NOTES

  • Warranty is valid for a period of 4 weeks, starting from the date of receipt of the package.
  • The Home Assistant Yellow is designed for the Compute Module 4 but is compatible with the Compute Module 5. However, when installing a CM5, do not use screws, as they may damage the CM5 board.
  • The existing heatsink fits the Compute Module 5, and the blue thermal pads work but require slight repositioning. The thermal pad for the main chip (BCM2712) is slightly too small, as the chip on the CM5 is larger, but this has minimal impact in practice. Overall, the existing cooling solution works quite well.  That said, the Compute Module 5 generates significant heat under full load. If your system is continuously under high CPU load, the CM5 may throttle performance over time due to heat.
  • If your 16GB CM5 is displaying only 8GB RAM on your HA Yellow, please make sure to upgrade to HAOS 16 or newer as this issue has been fixed on HAOS 16.

Good product - Documentation and Support could be better.

Received the unit quickly. Could not gain access. It appeared that Home Assistant was preinstalled despite support saying it wasn't. You need RPI-Boot to prep this for an installation. Every search for RPI Boot seems to lead you to Raspberry PI Imager, which.. RPI (boot) seems like the product. IT'S NOT. Once I figured that out, everything went smoothly. I formatted the NV ME drive and THEN used Raspberry Pi Imager to install an new instance of Home Assistant with the OS and it's up and running with ease.

Without this confusion that wasted almost a day, I'd give it five stars.

Hello,
Thank you for your feedback and for sharing your experience with the HA Yellow Essential Kit w/CM5. We’re glad to hear the unit arrived quickly and that you were able to get it up and running smoothly with Home Assistant.

We apologize for the confusion regarding the preinstallation of Home Assistant. As noted in the product description for the HA Yellow Essential Kit w/CM5, Home Assistant is indeed flashed on the NVMe or eMMC prior to shipping. We couldn’t find any record of communication indicating our support team advised otherwise, but we’re sorry for any misunderstanding that may have occurred.

To clarify for future users, our Essential, Advanced, Pro Lite and Pro Kits come with Home Assistant preinstalled. However, if reformatting or reinstalling, Raspberry Pi Imager is the correct tool for installing a fresh instance of Home Assistant, as you discovered but we recommend following Home Assistant Official Documentation (https://support.nabucasa.com/hc/en-us/categories/24734575925149). We have found that RPiBoot is not easily found on Google and indeed RPiBoot is diferent from RPi Imager, the former contains the drives to allow your CM5 eMMC/NVMe (on the Yellow) to be detected by a computer, while RPi Imager flashes the HAOS to either the eMMC or NVMe. The good things about the official documentation is that the link to RPiboot is there and the download will autoamtically start without having to search on Google (https://github.com/raspberrypi/usbboot/raw/master/win32/rpiboot_setup.exe) later on on that same documentation you will be linked to the Raspberry Pi imager.

Thank you for your honest feedback—it helps us improve. We’re happy to hear the system is now running well, and we’d be glad to assist further if you have any questions or need additional support.

Best regards,
Brandon

Long delay

Ordered in Dec '24, delivered in May '25

We’re so sorry for the inconvenience caused by the delay in your order. As indicated in our pre-order policy, delays can sometimes occur due to circumstances beyond our control. Raspberry Pi originally promised delivery to us in December 2024, but that date was repeatedly postponed. We updated our product page with the latest information as we received it. We finally received the 16GB RAM CM5 in May 2025 and shipped all pre-orders as quickly as possible. We truly appreciate your patience and understanding, and we’re here to assist with any further concerns!
