Hermes Agent for Home Assistant: Your Smart Home Just Got a Persistent AI Brain

**Hermes Agent for Home Assistant, Your Smart Home Just Got a Memory**

If you’ve ever wished your smart home could actually *remember* things about you, not just react to triggers, this might catch your attention.

The Hermes Agent Home Assistant Add-on, built by Wolfram Ravenwolf and powered by the self-improving AI agent from Nous Research, brings a persistent AI brain directly into your Home Assistant setup. And yes, it lives right inside your existing dashboard.

Let’s slow that down for a second.

We’re not talking about another simple automation. Hermes is designed as a **persistent AI agent with memory**, meaning it can retain context, improve over time, and connect across platforms. It supports multi-platform messaging and even includes a plugin architecture, so you can extend it with custom tools. If you’ve ever tinkered with Home Assistant and thought, “I wish this could think a bit more on its own,” this is that next step.

Installation is handled as a proper Home Assistant add-on. Configuration happens partly in the familiar UI, under Settings and Apps, and partly through a built-in terminal. API keys can be set conveniently through environment variables, which are written into the internal .env file at startup. Just one small thing to keep in mind, clearing values in the UI does not remove them from the file, so you’ll need to edit it directly if you want a full reset. I’ve learned the hard way that little configuration details like that matter.

Security is taken seriously. You can enable a web terminal or API server, protect access with a password, and use HTTPS with auto-generated certificates, or provide your own. It runs inside a Debian Bookworm container, with everything stored under /config, so updates and backups won’t wipe your setup.

What I find most interesting is where this is heading. A home assistant that doesn’t just respond, but adapts. One that integrates with tools like Open WebUI or other OpenAI-compatible systems. It feels less like scripting automations and more like collaborating with an evolving system.

And we’re only at the beginning of what that could look like in everyday life.
