Adapter oficial MQTT — descoberta e pub/sub genéricos sobre o broker da casa, o transporte com o maior leque de dispositivos por linha de código.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# MQTT

O primeiro transporte do epic, e o de maior alcance: qualquer dispositivo que
publique num broker (ESP32 caseiro, zigbee2mqtt, Tasmota, Shelly) entra sem
driver de fabricante.

## O que este skill declara

- `transport: mqtt` — o core (`garraia-hardware`, feature `mqtt`) fala TCP
  com o broker via `rumqttc` e segue a convenção de tópicos
  `garra/devices/<id>/…`;
- capabilities genéricas e dois presets de exemplo.

## Convenção de tópicos

| Tópico | Sentido |
|---|---|
| `garra/devices/<id>/manifest` | o dispositivo se anuncia (retained): id, capabilities e risco |
| `garra/devices/<id>/state` | estado atual, resposta de leitura |
| `garra/devices/<id>/get` | o Garra pede uma leitura |
| `garra/devices/<id>/set` | o Garra executa uma ação |

O id de registro sai namespaceado como `mqtt:<id>` (#1168) — um dispositivo
não alcança a chave de outro transporte.

## Risco

No MQTT, o risco chega no manifesto que o **dispositivo** publica, e o
adapter o aceita como piso — placa hostil não consegue se declarar mais
segura do que é, porque o catálogo de skills só aplica `max()` sobre ele.
Para uma tomada que na sua casa alimenta algo sério (o portão, uma bomba),
…

How to install

The exact contents, by fingerprint
mdr add michelbr84/garrarust/mqtt@sha256:3a31bb6267438ae0

The line at the top of this page pins the label git:20260913.38a8ac8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
