Overview

The Environmental Measurement Plugin will allow you to connect environment sensors to report conditions to your mesh. Examples are temperature, humidity and gas pressure.

Settings

Setting	Acceptable Values	Default
environmental_measurement_plugin_measurement_enabled	true, false	false
environmental_measurement_plugin_display_farenheit	true, false	false
environmental_measurement_plugin_read_error_count_threshold	integer	0
environmental_measurement_plugin_recovery_interval	integer (seconds)	0
environmental_measurement_plugin_screen_enabled	true, false	0
environmental_measurement_plugin_sensor_pin	integer	0
environmental_measurement_plugin_sensor_type	0-6	0
environmental_measurement_plugin_update_interval	integer (seconds)	0

environmental_measurement_plugin_measurement_enabled

Enables the plugin.

environmental_measurement_plugin_display_farenheit

The sensor is always read in Celsius, but the user can opt to view the temperature display in Fahrenheit using this setting.

environmental_measurement_plugin_read_error_count_threshold

Sometimes sensor reads can fail. If this happens, we will retry a configurable number of attempts. Each attempt will be delayed by the minimum required refresh rate for that sensor

environmental_measurement_plugin_recovery_interval

Sometimes we can end up with more than read_error_count_threshold failures. In this case, we will stop trying to read from the sensor for a while. Wait this long until trying to read from the sensor again.

environmental_measurement_plugin_screen_enabled

Enable/Disable the environmental measurement plugin on-device display.

environmental_measurement_plugin_sensor_pin

Specify the preferred GPIO Pin for sensor readings. May not be needed if using I2C.

environmental_measurement_plugin_sensor_type

Specify the sensor type.

Value	Description
0	DHT11
1	DS18B20 (Dallas 1-wire)
2	DHT12
3	DHT21
4	DHT22
5	BME280
6	BME680

environmental_measurement_plugin_update_interval

Interval in seconds of how often we should try to send our measurements to the mesh.
