老上菱单冷空调，96年生产，虽然很久，本着勤俭持家的原则还是不换了。遥控器死难用，北鼻无奈买了一个米家空调伴侣2，搞笑的是居然无法匹配？？！！唉。。。。。
自己做一个控制板吧，拆除原室内机内脏
在地上随便捡一个旧的风盘控制器改造一下，风盘控制器有零线/火线/风机高挡/风机中挡/风机低挡和阀控接线端子，刚好为我所用。阀控继电器功率较小，经检查发现空调室外机继电器刚好也是12v控制，所以就从风盘阀控继电器弱电端直接驱动原空调室内机内的室外机继电器。
diy需要灵活运用，灵活发挥。
加入室内温度检测和室内机换热器温度检测
装机测试
已通过巴法云接入小爱同学，效果还不错，现已正常服役，可显示送风模式档位、制冷设定的稳定、关闭状态、关闭5秒后显示时钟。
红外控制待完善。代码如下：
