如题。
配置如下，问每秒刷新的 text_sensor 是否会被 on_loop 中的 delay:3s 阻塞？

# 循环检查 wifi 状态，修改指示灯。
on_loop:
then:
- light.turn_on: red_light
- delay: 3s
- light.turn_off: red_light
wifi:

经过测试
on_loop:
then:
- light.turn_on: red_light
- delay: 3s
- light.turn_off: red_light
这样写是错误的。
这三个动作都是 同时进行。on 和 off 还有delay 分别是三个不同的任务。
并不是没有办法，从 esphome 翻译过来的 C++ 文件看，这样写是不对的，这样他生成了三个自动化实例，然后多任务（只是猜测）执行他们。
delayaction = new DelayAction<>();
App.register_component(delayaction);
delayaction->set_delay(4000);
light_lightcontrolaction_5 = new light::LightControlAction<>(red_light);
light_lightcontrolaction_5->set_state(false);
automation_2->add_actions({light_lightcontrolaction_4, delayaction, light_lightcontrolaction_5});
但是 换一个做法。
on_loop:
then:
lambda: |-
// 如果 WIFI 连接上了
if (id(wifi_state).is_connected())
{
//ESP_LOGD("WIFI","WIFI connected Code:%d",int(id(wifi_state).is_connected()));
// 蓝灯未亮起
if (!id(blue_light).remote_values.get_state())
{
auto blue_light_on = id(blue_light).turn_on();
blue_light_on.perform();
}
}
// 如果 WiFi 未连接
else
{
//ESP_LOGD("WIFI","WIFI not connect Code:%d",int(id(wifi_state).is_connected()));
auto blue_light_off = id(blue_light).turn_off();
auto red_light_on = id(red_light).turn_on();
red_light_on.perform();
delay(3000);
auto red_light_off = id(red_light).turn_off();
red_light_off.perform();
}
直接在 on_loop 中写 lambda 的话，使用 delay(3000) 就会阻塞主程序。
所以 on_loop 里面不能使用 lambda 来写 delay。
实现 WIFI 指示灯的功能如下：
