从最早开始用esphome，到现在，见证了它一步步变得完美
从最早得连wifi密码只能写死，到后面能ap模式练上去改密码
以前一直用esphome的原生api，后面发现设备多了。经常出现串设备。
只能转头mqtt协议了。mqtt也面临这同一个问题，mqtt的链接参数只能写死
直到202311月更新，出了一个text的空间。这下就好办了，研究了一个晚上，终于搞定了让esphome在web页面上修改mqtt参数
下面是效果图，web页面上有一个输入组件，填写对应的参数之后，点一下setupmqtt这个按钮，然后再点一下restart按钮，esphome重启之后就会用新的参数去连接mqtt服务器了但是切记，要点网页的restart按钮，断电重启不一定会保存参数。
点reset按钮可以让esphome恢复成默认参数
在hass的自动发现页面如下效果图
下面是喜闻乐见的代码部分了，将下面的配置插入到你的配置文件，你自己有 的部分就修改为我配置内容的，你自己配置文件没有的就把这些复制到你的配置文件。

自行修改这下面的内容，这里是原始mqtt的配置参数

mqtt_port_: '1883'
mqtt_user_: pi
mqtt_password_: xxxxxxx
