Integration

Home Assistant integration

Home Assistant REST API for a self-hosted instance: read the state of every entity, call services to actually control lights, switches and other devices, fire and list events, read recorded state history and logbook entries, list calendars and their events, download a camera still, validate the configuration and read the instance configuration. Point the credential at your own Home Assistant host and authenticate with a long-lived access token created from your user profile.

The workflow builds itself.

When this happens, do that in Home Assistant.Built from the 16 Home Assistant tools below, on the connection you add once.

Common Home Assistant use cases

validating a new Home Assistant credential
turning a light or switch on from a workflow
cleaning up a virtual sensor a workflow created earlier
validating the configuration before triggering a restart
charting how a temperature sensor moved over the last day
checking that an event type has a listener before firing it
explaining in plain language why a light turned on last night
attaching a camera snapshot to an alert when motion is detected
discovering the exact service name and fields before calling it
finding the calendar entity identifier before reading its events

What you can do with Home Assistant

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Use Home Assistant from Claude Code, Cursor or Codex

Connect Home Assistant in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Home Assistant operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"
