landbook-api

Unofficial Python client for the Landbook smart home cloud API (Netprisma/Landecia), reverse-engineered from the Landbook iOS app. Covers:

• REST: email/password login, token refresh, device discovery, TSL (Thing Specification Language) model fetch, device attribute reads.
• MQTT: a persistent WebSocket/TLS pub-sub connection for real-time device control and state (LandbookMQTTClient).

This library powers the landbook-ha Home Assistant integration, but has no dependency on Home Assistant and can be used standalone.

Installation

pip install landbook-api

Usage

from landbook_api import login, get_device_list, get_tsl, LandbookMQTTClient

bearer_token, uid, refresh_token = login("you@example.com", "your-password", region="us")

devices = get_device_list(bearer_token, region="us")
pk = devices[0]["productKey"]
dk = devices[0]["deviceKey"]

properties = get_tsl(bearer_token, pk, region="us")

client = LandbookMQTTClient(uid, bearer_token)
client.connect()


def on_message(topic_suffix: str, payload: dict) -> None:
    print(topic_suffix, payload)


device_id = f"qd{pk}{dk}"
client.subscribe_device(device_id, on_message)
client.send_read(device_id, pk, dk, [p["code"] for p in properties])

Async equivalents (async_login, async_get_device_list, async_get_tsl, async_refresh_token, async_get_device_attributes) are also exported — each wraps the sync call in a thread executor.

Supported Regions

Pass region="us", "eu", or "cn" to any call (defaults to "us"). EU and CN are untested — reports welcome via issues.

Session Tokens

login() returns a (bearer_token, uid, refresh_token) tuple. The access token (bearer_token) is valid for 2 hours; the refresh token is valid for 30 days and must be used to obtain a new pair via refresh_token() before the access token expires. Both values should be persisted by the caller — this library does not manage token storage.

Development

pip install -e ".[test]"
pytest

Disclaimer

This is an unofficial, reverse-engineered client with no affiliation to Landbook, Netprisma, or Landecia. It may break if the upstream API changes.
