Frequently Asked Questions
Can I run other applications alongside Home Assistant on the same machine?
You certainly can, especially if you use a hypervisor like Proxmox. This allows you to carve out a specific portion of your hardware for Home Assistant while using the rest for a media server or file storage. Just ensure you have enough overhead in your CPU and RAM to handle the combined load.
Is a refurbished mini PC a smart investment?
Buying refurbished is a fantastic way to stretch your budget. Many corporate-grade machines from Dell, HP, or Lenovo are retired after only a few years of office use. These are often built to last and provide significantly more reliability than cheaper, brand-new consumer units.
Do I need a dedicated Zigbee or Z-Wave controller?
Yes, you will need a separate USB stick to communicate with these protocols. Home Assistant does not have these radios built into the hardware of a standard mini PC. A universal coordinator will let you link all your switches and sensors directly to your local network.
How much electricity does one of these units use?
These machines are incredibly efficient. Most mini PCs idle at 5 to 10 watts of power, which is comparable to a single LED light bulb. You can leave them running 24/7 without seeing a meaningful increase in your monthly utility bill.
What happens if the power goes out?
Like any computer, these machines will shut down during a power loss. If you want to keep your smart home alive during a flicker, consider plugging the mini PC into a small uninterruptible power supply. This will give you enough time to perform a safe shutdown or keep your critical automations running until the grid returns.
