# ampio-mqtt

Async Python client for the **Ampio Smart Home** local MQTT protocol exposed by
the Ampio M-SERV controller. Built to back a Home Assistant integration while
staying Home Assistant agnostic itself.

> **Beta.** Everything below `1.0.0` can break between any two releases without
> migration shims, so pin exact versions. `1.0.0` is reserved for the release
> that accompanies the
> [home-assistant/core](https://github.com/home-assistant/core) integration
> being accepted upstream.

## Installation

```
pip install ampio-mqtt
```

LAN discovery (`discover()`) needs the `discovery` extra
(`pip install ampio-mqtt[discovery]`), which pulls in `zeroconf`. Home Assistant
ships `zeroconf` itself, so the integration needs no extra.

## Quickstart

```python
import asyncio

from ampio_mqtt import AmpioClient, ObjectUpdated, discover


async def main() -> None:
    found = await discover()  # mDNS lookup of ampio.local
    if found is None:
        raise SystemExit("No Ampio M-SERV found on the LAN")

    client = AmpioClient(found.address, "user", "secret")
    client.subscribe(
        lambda e: print(e.object.id, e.object.kind, e.object.state),
        of=ObjectUpdated,
    )
    await client.connect()  # connect, subscribe, request the catalogues

    rooms = await client.fetch_rooms()
    for obj_id, room in rooms.items():
        print(f"object {obj_id} -> {room}")

    await asyncio.sleep(30)
    await client.disconnect()


asyncio.run(main())
```

## What it does

Each area is one page under [`docs/`](docs/README.md), and the docstrings carry
the API detail.

- A maintained broker connection with QoS 1 on every leg but the retained raw
  state tree, and a capped-backoff reconnect. One typed event stream carries
  every update and the terminal `AuthFailed` and `ConnectionDied` signals
  ([`docs/events.md`](docs/events.md)).
- Discovery of the object catalogue on either account tier (the module catalogue
  is admin-only), with the detected tier exposed for setup flows
  ([`docs/account-tiers.md`](docs/account-tiers.md)).
- Classification of every object into a sensor, input, output, or thermostat
  kind with Home-Assistant-compatible hints
  ([`docs/classification.md`](docs/classification.md)).
- Replacement-stable identity for objects and modules, so a hardware swap keeps
  its entities ([`docs/identity.md`](docs/identity.md)).
- Commands for relays, dimmers, RGBW lights, covers with stop and tilt, the
  regulator setpoint, scenes, and bus events. The M-DOT panel buzzer and the
  module identify LED are admin-only. The `command()` escape hatch sends any
  other `/api` verb ([`docs/commands.md`](docs/commands.md)).
- A low-latency input bridge from the raw per-channel topics on the admin tier
  ([`docs/raw-channel-bridge.md`](docs/raw-channel-bridge.md)).
- Room mapping, per-module health, eviction events for server-side deletions,
  and connection diagnostics for a consumer's report blob.
- LAN discovery of the M-SERV by multicast DNS, self-contained in the process
  ([`docs/discovery-flow.md`](docs/discovery-flow.md)).

## Choosing an account

A dedicated standard account is the recommended shape for Home Assistant. It
sees exactly the objects granted in the Ampio app and can command only those. An
administrator account adds the module catalogue, the low-latency raw tree, the
module diagnostics, and the CAN write surfaces (panel LEDs, the buzzer, and the
identify LED). Bus events are the exception on both tiers. Any account can raise
any event number, and the logic behind an event runs with full authority.
[`docs/account-tiers.md`](docs/account-tiers.md) has the capability table and
the measured latency difference.

## Supported M-SERV versions

The library is developed and live-tested against an M-SERV self-reporting
`serverVersion` 1865 (`serverRevision` 409, `mqttVersion` 5.133.11). That
baseline is the compatibility floor. Wire behavior documented in this repo is
verified against that install unless marked otherwise in place - an open claim
says exactly what is unverified. Older servers are not supported, and the
library logs a warning when the connected server reports a lower or missing
`serverVersion`.

Ampio does not guarantee the stability of these wire surfaces. A server update
or a module firmware update can change or remove behavior this library depends
on, without notice. Breaking changes by Ampio are a known pattern. The author of
an earlier Ampio integration
[stopped maintenance for exactly this reason](https://github.com/kstaniek/ampio-hacc/issues/2).

### Upgrade rules

- If something misbehaves on an older server, upgrade the M-SERV first.
- If your install meets the baseline and works, stay on your current versions.
  Do not chase the latest ones.
- If you decide to update anyway, make a full backup first - ideally a full
  image of the M-SERV's microSD card.

## Disclaimer

This library is an independent, best-effort project and has no affiliation with
Ampio. Use it at your own risk. It commands real hardware, and a wrong command
moves real devices.

The M-SERV itself guarantees the safety of a standard account. The broker limits
such an account to the objects granted in the Ampio app, and it denies the raw
CAN surfaces on the wire. A defect in this library cannot widen that boundary.
Bus events are the one exception (see
[Choosing an account](#choosing-an-account)).
