ESP + BME680 + SSD1306 display

Initial prompt

generate an esphome configuration to send sensor data of BME680 to home-assistant

Response:

  esphome:
  name: my_sensor
  platform: ESP32

# Enable the BME680 sensor
sensor:
  - platform: bme680
    name: "BME680 Sensor"
    temperature:
      name: "Temperature"
      unit_of_measurement: "°C"
    humidity:
      name: "Humidity"
      unit_of_measurement: "%"
    pressure:
      name: "Pressure"
      unit_of_measurement: "hPa"
    air_quality:
      name: "Air Quality"
      unit_of_measurement: "ppm"

# Enable MQTT to send the sensor data to Home Assistant
mqtt:
  broker: YOUR_MQTT_BROKER_ADDRESS
  client_id: my_sensor
  username: YOUR_MQTT_USERNAME
  password: YOUR_MQTT_PASSWORD

# Configure the sensors to be published to MQTT
binary_sensor:
  - platform: mqtt
    name: "Temperature"
    state_topic: "my_sensor/sensor/temperature"
  - platform: mqtt
    name: "Humidity"
    state_topic: "my_sensor/sensor/humidity"
  - platform: mqtt
    name: "Pressure"
    state_topic: "my_sensor/sensor/pressure"
  - platform: mqtt
    name: "Air Quality"
    state_topic: "my_sensor/sensor/air_quality"

This configuration will enable the BME680 sensor and send the temperature, humidity, pressure, and air quality data to Home Assistant via MQTT. You will need to replace YOUR_MQTT_BROKER_ADDRESS, YOUR_MQTT_USERNAME, and YOUR_MQTT_PASSWORD with your own MQTT broker address, username, and password.

I hope this helps! Let me know if you have any questions.

use the specific board

it is connected on pin 6 of an ESP8266 nodemcu v4

Request to use a display

I'd also like to display the current sensor values on a SSD1306 with a refresh rate of 30seconds

Response:

To display the current sensor values on a SSD1306 OLED display with a refresh rate of 30 seconds, you can use the ssd1306 component in ESPHome and set the update interval for the sensor values to 30 seconds.

Here is an example configuration that will display the temperature, humidity, pressure, and air quality values from the BME680 sensor on a SSD1306 OLED display with a refresh rate of 30 seconds:

  esphome:
  name: my_sensor
  platform: ESP8266

# Enable I2C on the ESP8266
i2c:
  sda: D2
  scl: D1

# Enable the BME680 sensor
sensor:
  - platform: bme680
    name: "BME680 Sensor"
    temperature:
      name: "Temperature"
      unit_of_measurement: "°C"
      update_interval: 30s
    humidity:
      name: "Humidity"
      unit_of_measurement: "%"
      update_interval: 30s
    pressure:
      name: "Pressure"
      unit_of_measurement: "hPa"
      update_interval: 30s
    air_quality:
      name: "Air Quality"
      unit_of_measurement: "ppm"
      update_interval: 30s
    # Specify the I2C bus and address of the BME680 sensor

      return format_string("Air Quality: {}ppm", id(air_quality).state);

Request some tweaks

the sensor should be named 'airQualityHallway' and humidity should be displayed next to temperature, not below it. Also show the date and time on the display

Change the display output

please align date/time in the bottom right corner. use a slightly larger font for temperature and humidity

Response:

To align the date and time in the bottom right corner of the OLED display, you can use the x and y coordinates of the display component to specify the position of the text on the display. You can also use the font_size option to specify a larger font size for the temperature and humidity values.

Here is an updated configuration that includes the changes you requested:

This configuration will display the temperature and humidity values in a larger font size and will align the date and time in the bottom right corner of the OLED display. The `text_sensor
