deputyOS vs Home Assistant
Home Assistant automates your home; deputyOS runs a personal AI assistant. Adjacent, complementary, and frequently run side by side.
Last reviewed
Short answer: Not competitors. Home Assistant controls your house; deputyOS is an assistant that can talk to it. Most people who want both should run both.
Where Home Assistant is the better choice
- Unmatched device support — thousands of integrations
- Mature, powerful automation engine with a huge blueprint library
- Enormous community and years of accumulated recipes
- Local control of physical devices, which is its whole point
- Excellent mobile apps and voice assistant integration
Where deputyOS is the better choice
- A general assistant rather than a home automation controller
- Channels — Telegram, Slack, Discord, Signal, Matrix, email
- Persistent memory and document knowledge across conversations
- Fleet management and per-device cost tracking
- Air-gapped tier with model weights baked in
Adjacent, not overlapping
Home Assistant is a home automation platform. Its job is knowing about your lights, sensors, locks and thermostats, and reacting to them. It is extraordinarily good at that and has integration coverage nothing else approaches.
deputyOS runs a personal AI assistant — something that reads your email, remembers context, answers over your documents, and takes actions through chat channels. It knows nothing about your Zigbee network.
Where people conflate them
Both have added things that look like the other. Home Assistant has voice assistants and LLM integration; deputyOS profiles can call Home Assistant’s API. That surface similarity hides quite different centres of gravity.
Ask Home Assistant to summarise a PDF and you are pushing well outside its design. Ask deputyOS to debounce a motion sensor and you are doing the same in reverse.
Running both
The usual arrangement is Home Assistant owning the devices and automations, with deputyOS as the conversational layer that can call it — so “turn the heating down when I leave” stays an automation, while “what did the energy monitor do last week, and is that unusual?” goes to the assistant.
They can share a machine or run separately. deputyOS supports mounting shares and calling local HTTP APIs, so reaching a Home Assistant instance on the same LAN is routine.
