    最近买了一台变频空调,海信贴牌的,3500制冷量变频一级能效机,WiFi功能用手机扫空调外壳二维码无法下载app,厂家售后(非海信)敷衍什么app在维护升级,一个多月之后**说在跟进。自己花了好几天时间找到相关资料,终于成功用rs485接口链接发送命令可以开机关机设置温度等操作,命令字串如下:

  下一步是搞个单片机带蓝牙、rs485接入空调wifi模块物理接口,通过蓝牙转发,再弄一个手机app与空调链接遥控空调。
好像还有获取空调状态信息的命令,还在研究中。有兴趣的网友可以联系我。

用海信通用遥控器可以遥控空调,所以确定是海信贴牌机。

楼主牛B啊!这么多命令

那些温度命令用代码可以合称为1个命令和参数,这里只是方便验证用rs485接口控制空调
 楼主| 发表于 2022-8-7 10:32:45 | 显示全部楼层
没有rs485接口的话,也可以从空调内机板wifi接口前端的ttl接入,rs485不熟悉容易出现各种怪问题。

海信有贴牌机吗?

我意思是海信为其他牌子代工的
