请问大佬，ESP8266接DHT22有问题

18801450050

ESPHome代码如下：

esphome:
  name: esp8266_0
  platform: ESP8266
  board: nodemcuv2

wifi:
  ssid: "******"
  password: "*****"

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Esp8266 0 Fallback Hotspot"
    password: "*****"

captive_portal:

# Enable logging
logger:

# Enable Home Assistant API
api:

ota:

sensor:
  - platform: dht
    pin: D0
    temperature:
      name: "Living Room Temperature"
    humidity:
      name: "Living Room Humidity"
    update_interval: 10s
    model: DHT22

复制代码

但ESPHome 的log里显示

[23:54:32][W][dht:160]: Requesting data from DHT failed!
[23:54:32][W][dht:060]: Invalid readings! Please check your wiring (pull-up resistor, pin number).
[23:54:32][D][sensor:092]: 'Living Room Temperature': Sending state nan °C with 1 decimals of accuracy
[23:54:32][D][sensor:092]: 'Living Room Humidity': Sending state nan % with 0 decimals of accuracy

换了 11 可以了 应该是22是总线型

11的精度太差了
