Set up a private voice-controlled home assistant

They ran a local AI on their own hardware and used voice to manage home tasks without sending data to outside services.

Done with Custom agent· Advanced· Oct 2026

What they did
They installed a local model with Ollama on their PC, choosing one small enough to fit their GPU. Voice input came through Whisper, and Piper handled spoken replies. That setup let the agent talk to a local Home Assistant system and carry out tasks like managing groceries, controlling lights and AC, checking garden moisture, and helping with language practice. Remote access was added with WireGuard or Tailscale.
How it went
The setup worked reasonably well for those jobs, but the model was weaker than cloud-based options. The main benefit was full local control with no outside data sharing.
Tips
This kind of build can take advanced setup work at the start. If you want privacy, keep the model, voice tools, and home system running on your own network.

Try it yourself with Hermes Agent

You are helping me build a voice-controlled home setup on my own machine. Use [local model name] through [local runtime] on [my computer specs], and connect it to [home automation platform] with voice input from [speech-to-text tool] and spoken replies from [text-to-speech tool]. I want it to handle [task 1], [task 2], [task 3], and [task 4], plus answer a question like "[example status question]". First, outline the steps and confirm which parts are safe to change. Before you make any irreversible or safety-sensitive change, such as sending a command, deleting data, changing heating, unlocking doors, or buying anything, stop and ask for my approval. After setup, test at least five spoken commands and report what worked, what failed, and any errors clearly.
