自从养了狗子，周末的懒觉都睡不成了，于是想偷偷懒搞个定时喂狗的东西，虽说网上一大堆机器，但对于一个diy上瘾的人来说还是自己搞比较有意思...成品长这样：

大概图形原理：

其实一开始的设想是做成这样：

这样的好处是可以一次倒进去很多，可以根据槽子的容积自动定量喂食，奈何理想很丰满~~转动的时候会卡狗粮~~无奈改成了现有的方案，不过能省一次算一次咯
配置用的esphome官方配置：链接

esphome:
  name: servos
  platform: ESP8266
  board: nodemcuv2

wifi:
  ssid: "wifi"
  password: "密码"
  manual_ip:
    static_ip: 192.168.0.222
    gateway: 192.168.0.1
    subnet: 255.255.255.0
  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Servos Fallback Hotspot"
    password: "VYTOwxqxxlOT"

captive_portal:

# Enable logging
logger:

# Enable Home Assistant API
api:
  services:
    - service: control_servo
      variables:
        level: float
      then:
        - servo.write:
            id: my_servo
            level: !lambda 'return level / 100.0;'

ota:

binary_sensor:
  - platform: gpio
    pin: D2
    name: "手动喂狗"
    on_state:
      then:
      - servo.write:
          id: my_servo
          level: -100.0%
      - delay: 2s
      - servo.write:
          id: my_servo
          level: 0%      
      
servo:
  - id: my_servo
    output: pwm_output


# Example output platform
# On ESP32, use ledc output
output:
  - platform: esp8266_pwm
    id: pwm_output
    pin: D5
    frequency: 50 Hz

HA配置：input_number: #喂狗
  servo_control:
name: Servo Control
initial: 0
min: -100
max: 100
step: 1
mode: slider

automation:
  - alias: Write Servo Value to ESP
trigger:
   platform: state
   entity_id: input_number.servo_control
action:
   # Replace livingroom with the name you gave the ESP
   - service: esphome.servos_control_servo
      data_template:
      level: '{{ states(''input_number.servo_control'') | int }}'

测试调用服务esphome.servos_control_servo，填level:-100就是反转90度，0是复位，100正转90度，自动化应该很简单，不过我用的node-red更简单所以就不贴啦

另外有大佬试过nodemcu控制两个舵机么，，我试了一下esphome两个同时接入会互相干扰，很无奈，目前想的是用手上的arduino搞，不过完全没研究过那个。。

加了个手动开关，，不知道有啥用，或者突然断网了手动喂一下？

这东西放在生活阳台，，，wifi好像有点不太好，老是失联，索性改成esphome定时算了，，有需要esp时间方面自动化的可以参考一下:Time

time:
  - platform: homeassistant
    id: homeassistant_time
    timezone: Asia/Shanghai
    on_time:
      - seconds: 0
        minutes: 30
        hours: 8
        days_of_week: MON-SUN
        then:
          - servo.write:
              id: my_servo
              level: -100.0%
          - delay: 2s
          - servo.write:
              id: my_servo
              level: 0%
      - seconds: 0
        minutes: 0
        hours: 12
        days_of_week: MON-SUN
        then:
          - servo.write:
              id: my_servo
              level: -100.0%
          - delay: 2s
          - servo.write:
              id: my_servo
              level: 0%
      - seconds: 0
        minutes: 30
        hours: 18
        days_of_week: MON-SUN
        then:
          - servo.write:
              id: my_servo
              level: -100.0%
          - delay: 2s
          - servo.write:
              id: my_servo
              level: 0%

直接加在上面的配置后面，从HA同步时间，然后定时执行
