HDMI切换器改造

602293544

首先买的是这一款HDMI 我的HDMI购买地址  5路输入1路输出 带红外遥控

见图


    大小的话正好放在盒子里面  用的esp是07，因为07可以外接天线，板载天线的没有测试不知道会不会有影响，HDMI上面的5个指示灯拆掉了，晚上太亮了影响睡觉，分析下  整个板子的GND都是共通的，led高电平正好可以触发光耦，板子上有空余5V，可以用来取电。红外接在外面这样不影响遥控器的使用，（打板之前没有规划好所以有点丑，大家想弄的话可以自己优化下）分析完成后开始着手准备，

    注意红外发射头请在刷机完成后在焊接，因为设计有问题不想改了，请大家自行修改加个跳帽就行。
Arduino写代码文件里有备注（esphome的红外有点问题，不能解析红外码，又不会自己写引用库，是我太菜了） HDMI.txt.zip (3.42 KB, 下载次数: 1, 售价: 1 金钱)

注意查看串口信息。
然后是Node Red的流程，ha的请自行编写。

有没有试过6个口全开着输入源输出源试下？我家一进三出的用esp01s，只要HDMI1设备一开，esp就掉线，不知道是断电了还是信号干扰了
