Further NUC PCs to consider for Home Assistant

Let’s compare the three NUC models based on the following criteria:


The NUC 13 Pro Mini is by far the most powerful PC on this list and widely overkill for just running Home Assistant on its own. I recommend installing Home Assistant in a VM on something like Proxmox and this will give you the flexibility of running more VMs on the PC.


My budget option of the Intel® NUC 11 Essential gives you plenty of performance and resource requirements to get up and running with Home Assistant OS. The NUC 11 Essential PC is also the most energy efficient using around 6W of power when running idle, making it the best NUC for Home Assistant.

How to Set Up Home Assistant on Your NUC

To install Home Assistant on a NUC PC simply follow the official guide using the generic x86-64 image of HAOS. The guide is based on a 7th-generation NUC and the same process can be followed for all other models.

For a more powerful Home Assistant NUC PC, I would recommend that you install a virtualisation platform such as VMWare ESXI or Proxmox then install Home Assistant OS inside a VM. This will give you the opportunity to use the remaining resources on your NUC for other systems such as Plex Media Server or running Docker Containers.

Troubleshooting Common NUC Issues with Home Assistant

  1. Overheating: Due to their small form factor, NUC PCs may experience overheating if not adequately ventilated. This can lead to performance throttling or unexpected shutdowns.
  2. Hardware Compatibility: Certain NUC models may face compatibility issues with specific hardware components, such as RAM or storage devices.
  3. BIOS and Firmware Updates: Updating the BIOS or firmware can sometimes cause problems, such as boot failures or instability if not done correctly. Follow the official NUC BIOS update instructions to ensure there are no issues.
  4. Noise and Fan Speeds: Depending on the NUC model and usage, fan noise and speeds may become bothersome under heavy load. Look at cleaning your fans if they become noisy to prevent failures.

Integrating NUC with Smart Home Devices

Integrating your NUC with smart home devices is a key step towards creating a seamless and efficient smart home automation system. By connecting your NUC to various smart devices, you can control and manage them from a centralized platform, making your daily life more convenient and comfortable.

With the availability of USB ports on a NUC you can use devices such as a Zigbee USB controller or Z-Wave USB stick.

NUC Maintenance and Upgrades

Proper maintenance and upgrades are essential to ensure the longevity and optimal performance of your NUC. Here are some useful tips to keep your NUC in top condition:

1. Regular Cleaning: Dust and debris can accumulate inside the NUC, leading to overheating and reduced performance. Regularly clean the vents and internal components using compressed air or a soft brush.

2. Monitor Temperatures: Keep an eye on your NUC’s temperature to avoid overheating. Install monitoring software to track temperature levels and take appropriate action if it exceeds safe limits.

3. Firmware and Software Updates: Stay updated with the latest firmware and driver releases from the NUC manufacturer. These updates often include performance improvements and bug fixes.

4. Storage Optimization: Regularly check your NUC’s storage usage. Remove unnecessary files and applications to free up space and ensure smooth operation.

5. RAM Upgrades: If your NUC supports RAM upgrades, consider adding more memory to improve multitasking and overall performance.

6. SSD Upgrade: Consider upgrading to a faster and larger SSD (Solid State Drive) to enhance system responsiveness and reduce boot times.

7. Backup Data: Regularly back up your data to an external storage device or cloud service to prevent data loss in case of hardware failure or other issues.

8. Check for Malware: Use reliable antivirus software to scan your NUC for malware and viruses regularly.

9. Power Management: Adjust your NUC’s power settings to balance performance and energy efficiency based on your usage requirements.

10. Avoid Overclocking: While overclocking may boost performance, it can also lead to increased heat and potential instability. Avoid excessive overclocking to maintain stability.

11. Keep in a Clean Environment: Ensure your NUC is placed in a clean and well-ventilated area to prevent dust buildup and maintain proper airflow.

12. Regularly Test Hardware: Periodically run hardware diagnostic tests to check the health of components such as the CPU, RAM, and storage.

13. Proper Shutdown: Always shut down your NUC properly using the operating system’s shutdown procedure to avoid data corruption or system errors.

14. Backup BIOS Settings: If you plan to update your NUC’s BIOS, back up your current settings to easily revert to them if needed.
