Pre-v0.9 Legacy Configuration Format

[!WARNING] Historical Archive: This document describes the deprecated configuration syntax used before version 0.9, where devices were declared under individual domain keys directly inside configuration.yaml (platform: myhome). For v0.9.x, devices must be declared in /config/myhome.yaml keyed by gateway MAC address.

Prior to v0.9.0, devices were configured inside the main Home Assistant configuration.yaml split across platform domains using platform: myhome:

1. Lights (light)

light:
  - platform: myhome
    devices:
      garage:
        where: '01'
        name: Garage
        dimmable: false
        manufacturer: Arnould
        model: 64391
      main_bedroom:
        where: '23'
        name: Main bedroom
        dimmable: true
        manufacturer: BTicino
        model: F418

2. Switches (switch)

switch:
  - platform: myhome
    devices:
      bed_heater:
        where: '0211'
        name: Mattress heating pad
        class: outlet
        manufacturer: BTicino
        model: F411U2

3. Covers (cover)

cover:
  - platform: myhome
    devices:
      living_shutter:
        where: '11'
        name: Living room shutter
        advanced: true
        manufacturer: Legrand
        model: 67557

4. Binary Sensors (binary_sensor)

binary_sensor:
  - platform: myhome
    devices:
      garage_door:
        where: '31'
        name: Garage door
        class: garage_door
        manufacturer: BTicino
        model: 3477

Why This Changed in v0.9.0

  1. Multi-Gateway Support: Placing devices under top-level domains in configuration.yaml made it impossible to specify which gateway controlled which device in multi-gateway installations.
  2. Centralized Configuration: In v0.9.0, all devices moved into /config/myhome.yaml under the specific gateway's MAC address (mac: '00:03:50:xx:xx:xx').
  3. v2.0 Transition: In v2.0+, manual YAML files are completely superseded by UI-first Config Flow with automatic bus discovery.
