Esphome 2025.2已支持MQTT自动加mac前缀

DIYSmartHome

以前一直用的是2024的版本，用的是以下方法加mac前缀

id(mqtt_client).set_topic_prefix("${topicrelayprefix}/" + App.get_name());

复制代码

升级2025的版本后，发现这set_topic_prefix函数报错了。
跟踪下代码发现，已经支持自动加前缀了：
也就是把MQTT里的topic_prefix设置成跟name:一样，就会自动MAC前缀
下面给个参考：

esphome:
  min_version: 2025.2.0
  name: smcurtain
  friendly_name: smcurtain
  name_add_mac_suffix: true
  on_boot:
    - light.turn_on:
        id: light_white_led
        brightness: 50%
    - light.turn_off: light_white_led

esp8266:
  board: d1_mini
  restore_from_flash: true


wifi:
  networks:
    - ssid: !secret ssid1
      password: !secret ssid1_password
  ap:
    ssid: ${devicename}
    password: 123456789
    ap_timeout: 2min
  fast_connect: False
  power_save_mode: none
  domain: .local

mqtt:
  id: mqtt_client
  broker: !secret mqtt_broker
  username: !secret mqtt_username
  password: !secret mqtt_password
  port: !secret mqtt_port
  discovery: False
  discovery_retain: False
  # discovery_unique_id_generator: mac
  # discovery_prefix: homeassistant
  topic_prefix: smcurtain
