关于日立空调接入HA的一些问题

user1075

1.首先第一步通过MQQT climate 创建了空调实体，

mqtt:
  climate:
      - unique_id: rilikongtiao1
        name: rilikongtiao1
        modes:
          - "off"
          - "heat"
          - "dry"
          - "cool"
          - "fan_only"
        fan_modes:
          - "high"
          - "medium"
          - "low"
          - "auto"
          - "silent"
        power_command_topic: "homeassistant/climate/zhonghong/1-1/power/set"
        mode_command_topic: "homeassistant/climate/zhonghong/1-1/mode/set"
        current_temperature_topic: "homeassistant/climate/zhonghong/1-1/cur_temp/state"
        mode_state_topic: "homeassistant/climate/zhonghong/1-1/mode/state"
        temperature_command_topic: "homeassistant/climate/zhonghong/1-1/temp/set"
        temperature_state_topic: "homeassistant/climate/zhonghong/1-1/temp/state"
        fan_mode_command_topic: "homeassistant/climate/zhonghong/1-1/fan/set"
        fan_mode_state_topic: "homeassistant/climate/zhonghong/1-1/fan/state"
        precision: 1.0

第二 通过node-red modbus 组件 与空调网关通信（空调网关可同时支持 ZigBee 及 485协议），具体流程及代码

通过涂鸦APP 控制 空调的 开关 模式  温度 等操作  MQQT climate 实体都可以接受到信息并改变实体状态，但通过MQQT climate 实体 去控制空调时 问题就来了，可以控制空调，但MQQT climate 实体状态不会改变，还是默认状态，而且过一会 空调的状态也会变为MQQT climate 实体的默认状态。


请各位大佬帮忙解惑，我对MQQT 原理不是很熟悉。

nodered代码好像不正确，没有倒全
说说我的理解，其实MQTT只是用来连接HA和nodered程序的，
所有的控制代码都是在Nodered程序来实现的，然后设备的结果也是反馈到NA程序。NA程序在根据MQTT规定的格式代码，将相关数据反馈给HA显示出来。反过来，HA的控制方面也是通过MQTT发送到NA，在NA转换成485命令去执行。


想问一下，有日立空调485的控制码吗？

有的 但是要有中央空调的中控网关
