pymacon

Secure async REST and WebSocket client for the Macon Heat Pump Controller. It is the transport library used by the Macon Home Assistant integration.

Each MaconClient owns the credential, pinned certificate, ordered state, reconnect loop, and reconciliation state for exactly one controller. Multiple controllers therefore remain fully isolated.

Install

pip install pymacon

Usage

from pymacon import MaconClient

client = MaconClient(
    "192.168.1.21",
    token,
    certificate_fingerprint,
    # arctic-* is retained because it is the firmware wire-format ID.
    device_id="arctic-001122334455",
)
client.subscribe(handle_snapshot)
client.subscribe_status(handle_status)
await client.start()

Call await client.stop() when unloading the owning config entry. Sessions passed into the constructor remain owned by the caller; sessions created by the client are closed automatically.

Control methods acknowledge that a command was accepted, but they never optimistically mutate local state. Subscribe to snapshots to observe the controller's reported state:

await client.async_set_cooling_setpoint(12)
await client.async_set_power(False)

Only controls advertised by client.capabilities should be called. The firmware rejects unavailable, unsafe, or unsupported operations.
