- HOME_ASSISTANT_URL — Base URL of the Home Assistant instance, e.g. https://abc123.ui.nabu.casa. It has to be a URL this process can actually reach: a server outside the house cannot route to 192.168.x.x, so a LAN-only home needs Home Assistant Cloud or the household's own reverse proxy.
- HOME_ASSISTANT_TOKEN — A Home Assistant long-lived access token (Home Assistant, your profile, Security, Long-lived access tokens, Create token). It carries the full rights of the account that minted it, so mint it from an account with only the access this agent should have.
- HOME_ALLOWED_ENTITIES — Comma-separated entity ids the person running this server has pre-approved for guarded actions, e.g. lock.office_door. This is the ONLY way an action that opens the house runs over stdio, and it is deliberately a human, out-of-band decision: no tool can add to it. Per entity, never per domain. Leave unset to refuse every such action.
Claude Code has no install link for a local command. Copy the command below and run it in a terminal.
