mihome-ctl 0.1.0

Passwordless QR login to the official Xiaomi cloud: extract per-device miIO tokens / BLE keys and control cloud IR remotes (TV / A-C / fan / DIY)

mihome-ctl

Passwordless QR login to the official Xiaomi cloud — extract every device's miIO token / local IP / BLE beacon-key, and control cloud IR remotes (TV / air-conditioner / fan / DIY on-off) through your home's parent blaster (e.g. a Xiao AI speaker). No local hardware, no Home Assistant required.

• Talks only to official hosts: account.xiaomi.com + {region}.api.io.mi.com
• Supports the tw / sg regions (python-miio / micloud have no tw locale)
• Produces per-device token + local IP + BLE key
• Passwordless (QR); secrets written with chmod 600

A thin wrapper over the Xiaomi-cloud-tokens-extractor connector (MIT, vendored + trimmed into mihome_ctl/connector.py, see THIRD_PARTY_LICENSES/) plus a cloud-IR control layer.

Install

uv tool install mihome-ctl          # or: pipx install mihome-ctl
# From source:
uv sync && uv run mihome-ctl --help

Optional extras:

uv tool install 'mihome-ctl[verify]'   # verify: LAN token check (python-miio)
uv tool install 'mihome-ctl[mcp]'      # MCP server (for Claude / agents)

Usage

mihome-ctl extract               # QR login, extract tokens (scans tw sg cn)
mihome-ctl extract --server tw sg   # specific regions (space-separated, not repeated flags)
mihome-ctl list                  # reprint last result offline
mihome-ctl verify --did <DID>    # LAN-verify one device (needs [verify])

mihome-ctl ir                    # list cloud miir.* remotes + parent blaster
mihome-ctl ir-send --remote <name> --key VOL+ [--repeat 3]
mihome-ctl ir-send --remote <name>            # omit --key to list a remote's keys
mihome-ctl ir-ac --temp 26 --mode cool        # absolute A/C control (state-based)
mihome-ctl ir-ac --off | --status
mihome-ctl ir-code --matchid xm_1_199         # IRDB matchid → per-key Pronto (see notes)

On first run a QR is drawn in the terminal (or open http://127.0.0.1:31415) — scan once with the Mi Home app; the session is cached in the state dir's mi-session.json, so subsequent runs skip the scan. Use --relogin to force a re-login.

State directory

Resolved in this order (secret filenames: mi-tokens.json / mi-session.json / mi-ir.json / devices.md):

1. MIHOME_CTL_HOME environment variable
2. the nearest ./.secrets/ walking up from the cwd (convenient when embedded as a submodule inside another repo)
3. otherwise platformdirs user state dir

All secrets are written with mode 0600.

Architecture — one core, many front-ends

mihome_ctl.core is a UI-agnostic layer (connector, cloud API, IR codec, operations) that only does work and returns structured data. Everything on top is a thin presentation layer:

• mihome_ctl.commands + __main__ — the Tyro CLI (commands above)
• mihome_ctl.mcp_server — an MCP server (mihome-ctl-mcp, needs [mcp])
• a future TUI would be one more presentation layer over the same core

ir-code and licensing (important)

ir-code decodes a Xiaomi IRDB matchid into Pronto: base64 → AES-128-ECB → gzip → microsecond timings → Pronto. The decoder is a clean-room implementation (from the public protocol, using pycryptodome), so this package contains no AGPL code, vendors nothing AGPL, and downloads no AGPL tool at runtime — it stays cleanly MIT.

Limitation (stated honestly): the public {region}-urc.io.mi.com/controller/code/1 endpoint currently requires a Mi Home app signature (anonymous requests return status:19), so fetching codes online by matchid is experimental. The decoder itself is verified by a round-trip test. To use an external IRDB tool (e.g. the AGPL-licensed ysard/mi_remote_database), install it yourself and opt in — this package deliberately does not depend on or bundle it (core/ircodec/base.py keeps an IRCodecBackend extension point for an external backend).

Development

uv sync --extra verify --extra mcp
uv run pytest -q
uv run ruff check . && uv run ruff format --check .
