Compare all 7 Home Assistant options
Pick the right setup
- Claude on the web or desktop with a custom connector connects from Anthropic's cloud. Your server must be reachable on the public internet.
- A local server (stdio) in Claude Code or Claude Desktop runs on your own machine and can reach Home Assistant on your network.
Stay safe
Start with read-only questions, such as which lights are on. Ask Claude to confirm before it unlocks a door, opens a garage or changes the heating.
“Live through our connector” runs through Real World MCP today. “Official MCP” is the vendor's own server. “Manual” means you or a browser use the provider's site. Prices are the provider's own and change. Browse every home & iot entry.
What people have done
- Have Claude Code add ESPHome sensors and drivers around the house
A user points Claude Code at a folder of ESPHome configs to add new devices, including sensor drivers. Their house now has a vinyl streamer, ESP32 speakers, plant sensors, a solar bird-house camera and a sleep sensor.
- Give your Home Assistant voice assistant a robot body
A maker's LLM-driven desk robot works as a Home Assistant voice assistant: it turns on lights, TV and AC, uses its camera to greet people entering the room, and comments when the 3D printer finishes.
- Add a timer and push alert to a smart plug in ten minutes with Claude
A Home Assistant user asked Claude for an automation that times a new candle warmer and asks by push alert whether to extend; it worked in under ten minutes and Claude suggested auto-off when nobody is home.
- Show your Kindle highlights on an e-ink display with Claude Code
A user flashed Seeed reTerminal e-ink screens with ESPHome and had Claude Code write the backend, so quotes they highlight on a jailbroken Kindle later show up on the display, all on the home network.
