1. Component

1) Raspberry Pi 3B+ is already installed Hass.io

2) ESP8266 board

3) DHT11 sensor

 

2. Make Temp&Humi Sensor Device

1) Input device and Wifi information

2) Edit yaml file

- If ESPHome Web show "404: Not found" error and can not read ".yaml" file, you clieck ESPHome button on navigation left side. Reload ESPHome Web.

- Add this configuration

# Example configuration entry
sensor:
  - platform: dht
    pin: D2
    temperature:
      name: "Living Room Temperature"
    humidity:
      name: "Living Room Humidity"
    model: DHT11
    update_interval: 60s

- You can find exmaple on ESPHome Document below picture. They said that the default model is AUTO_DETECT. But AUTO_DETECT model choose DHT22 despite I use DHT11. So Manually specify the DHT model, DHT11.

3. Check ESP8266's IP

4. Setup Integrations and UI card

Input Device IP you copied when Upload.
