Now go to Home Assistant, ESPHome (See illuminance tutorial if needed).
Here is the code to use (Use previously generated code before output declaration, with your own keys instead of ***) :
esphome:
name: multisensor1
friendly_name: MultiSensor1
esp8266:
board: d1_mini
# Enable logging
logger:
# Enable Home Assistant API
api:
encryption:
key: "*****************************"
ota:
password: "**************************"
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: "Multisensor1 Fallback Hotspot"
password: "*******************"
output:
- platform: esp8266_pwm
id: RGB_Led_Red
pin: D5
- platform: esp8266_pwm
id: RGB_Led_Green
pin: D6
- platform: esp8266_pwm
id: RGB_Led_Blue
pin: D7
light:
- platform: rgb
name: "LED RGB"
red: RGB_Led_Red
green: RGB_Led_Green

Nothing more needed. Send the firmware to the WeMos D1.
Go to settings in Home Assistant, devices, select ESPHome integration, devices –> MultiSensor1
