MQTT best current practice

[TomLee]

Magst du die These verifizieren, dass man auch keine readingList benötigt, wenn man so einen Shelly hat?

Stichwort: ParseFn() in discovery setzt die readings, Code aus mqtt_generic_bridge transferieren.

Geht:

defmod shelly1minig3_e4b3231cf8a8 MQTT2_DEVICE shelly1minig3_e4b3231cf8a8
attr shelly1minig3_e4b3231cf8a8 autocreate 0

setstate shelly1minig3_e4b3231cf8a8 2026-09-18 18:50:59 state off
Alle neuen Schalter sind Attribute am MQTT2_DISCOVERY-Device und stehen default auf 0. Ohne
sie verhaelt sich das Modul wie bisher: readingList und setList am Geraet, und alle erkannten
Readings sind sichtbar.

Attribut             Vorgabe        Wirkung bei 1
readingsViaParse     0              kein readingList-Attribut, Auswertung in ParseFn
setsViaHook          0              kein setList-Attribut, Befehle über den Hook
fhemConventions      0              ein Kanal: state, on/off statt true/false
availabilityReading  availability   none: kein verdichtetes Reading, nur lwt

Nach dem Umschalten genuegt set <discovery> rebuildDevice <device>.

Payloads zum Nachstellen ohne Mini Gen3

Der Adapter fragt ueber `<prefix>/rpc` nacheinander `Shelly.GetDeviceInfo`, `Shelly.GetConfig`,
`Shelly.GetStatus` und `Shelly.GetComponents` ab. In jeder Anfrage stehen `id` und `src`; die Antwort
gehoert auf `<src>/rpc`, mit derselben `id` und `"src":"<geraete-id>"`. Damit laesst sich das Geraet
mit mosquitto_pub vollstaendig simulieren.
Hier die vier Antwortinhalte, echte Werte eines Shelly 1 Mini Gen3 mit FW 2.0.0:
