  board: nodemcuv2

wifi:
  ssid: "YOUR_SSID"
  password: "YOUR_PASSWORD"

sensor:
  - platform: dht
    pin: D2
    temperature:
      name: "Living Room Temperature"
    humidity:
      name: "Living Room Humidity"
    update_interval: 60s

Advanced users can customize their configurations with additional sensors, automations, and security settings. Security considerations include using strong Wi-Fi passwords and enabling encryption for data transmission.
