LLMs are here to stay, and they are fundamentally changing how we interact with machines\u2014especially when it comes to smart homes and Home Assistant.<\/p>\n\n\n\n

In this article, I\u2019m walking you through my personal setup and how I use local LLMs with my Home Assistant instance. I\u2019ll also share the pitfalls to avoid and best practices for anyone looking to integrate LLMs into their own smart home. This post is a continuation of my previous article about my experiences with the Home Assistant Voice PE<\/a>, so you might want to check that out first before diving in here.<\/p>\n\n\n\n

Cloud vs. Local LLMs<\/h2>\n\n\n\n

Before going fully local, I used cloud-based LLMs for a while. While cloud models are a fantastic starting point, you eventually start wondering if things would be better running entirely on your own hardware.<\/p>\n\n\n\n

Here is a quick breakdown of why I made the switch:<\/p>\n\n\n\n

Feature<\/td>Cloud LLMs<\/td>Local LLMs<\/td><\/tr><\/thead>
Performance<\/strong><\/td>Exceptional and fast (powered by massive remote servers).<\/td>Depends heavily on your local hardware (GPU).<\/td><\/tr>
Privacy<\/strong><\/td>Your entities and data are sent to the cloud (often used for training).<\/td>100% private. Data never leaves your network.<\/td><\/tr>
Reliability<\/strong><\/td>Dependent on your internet connection.<\/td>Works offline. If the internet drops, your house still listens.<\/td><\/tr>
Cost<\/strong><\/td>Requires API tokens; fractions of a cent per query add up over time.<\/td>Higher upfront hardware cost, but free to query (minus electricity).<\/td><\/tr>
Learning Experience<\/strong><\/td>Black-box setup; it’s plug-and-play, but you don’t get to see how the magic happens.<\/td>Hands-on tinkering; you learn exactly how LLMs are built, set up, and managed under the hood.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

<\/p>\n\n\n\n

For me, the API costs weren’t a dealbreaker, but I love experimenting and demand total local control over my smart home. So, I went all-in on local.<\/p>\n\n\n\n

My Local Hardware & Setup<\/h2>\n\n\n\n

The goal for this build was to keep it as affordable and energy-efficient as possible. Almost all the parts (except the SSD) are recycled, either sourced from friends and family or bought from second-hand marketplaces.<\/p>\n\n\n\n
