Plugin details

Type: Environment

Name: BME68x

Status: COLLECTION B CLIMATE

GitHub: P106_BME680.ino

Maintainer: TD-er, tonhuisman

Used libraries: https://github.com/adafruit/Adafruit_BME680

Description

Plugin to use the Bosch BME680 and BME688 Temperature, Humidity, Barometric pressure and MOX Gas resistance values.

Warning

For the BME688 sensor the AI features are not supported, only the BME680 features, as it is fully backward compatible.

Specifications:

  • Temperature (-40C to +85C)

  • Relative humidity (0-100 %RH)

  • Barometric pressure (300-1100 hPa)

  • Gas resistance (can be used to determine IAQ, Index of Air Quality)

configuration

../_images/P106_DeviceConfiguration.png

  • Name: Required by ESPEasy, must be unique among the list of available devices/tasks.

  • Enabled: The device can be disabled or enabled. When not enabled the device should not use any resources.

I2C options

  • I2C Address: The device supports 2 addresses, that can be configured using the SDO pin: (not all boards have that pin available, but could use soldering-pads to configure the address)

The available I2C settings here depend on the build used. At least the Force Slow I2C speed option is available, but selections for the I2C Multiplexer can also be shown. For details see the Hardware page

Device Settings

  • Altitude When not at sea-level, the plugin can apply an altitude compensation on the Pressure value.

  • Present `Gas` in Ohm (not kOhm): Normally the Gas resistance value, received from the MOX Gas sensor, is divided to be presented as kOhm, but with this setting checked, the native Ohm value is shown.

Data Acquisition

This group of settings, Single event with all values and Send to Controller settings are standard available configuration items. Send to Controller is only visible when one or more Controllers are configured.

  • Interval By default, Interval will be set to 60 sec. The data will be collected and optionally sent to any configured controllers using this interval.

Values

The plugin provides the Temperature, Humidity, Pressure and Gas values. A formula can be set to recalculate. The number of decimals can be set as desired.

Per Value is a Stats checkbox available, that when checked, gathers the data and presents recent data in a graph, as described here: Task Value Statistics:
