:::warning GPIO access is fundamentally dangerous because invalid options can physically damage or destroy your hardware. Ensure that you fully understand the schematic for your particular device before trying this as we do not offer a warranty. Use at your own risk. :::

:::note This module requires attaching a peripheral accessory to your device. It will not work without one. :::

Overview

The Telemetry Module will allow nodes to send a specific message with information from connected sensors. Currently supported sensors are BME280, BME680, DHT11, DHT12, DHT21, DHT22 and Dallas 1-wire DS18B20.

:::tip Once module settings are changed, a reset is required for them to take effect. :::

Settings

Setting Acceptable Values Default
telemetry_module_display_farenheit true, false false
telemetry_module_measurement_enabled true, false false
telemetry_module_read_error_count_threshold integer 0
telemetry_module_recovery_interval integer (seconds) 0
telemetry_module_screen_enabled true, false 0
telemetry_module_sensor_pin integer 0
telemetry_module_sensor_type 0-6 0
telemetry_module_update_interval integer (seconds) 0

telemetry_module_display_farenheit

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

telemetry_module_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

telemetry_module_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.

telemetry_module_sensor_pin

:::note The preferred setup is using I2C, so the telemetry_module_sensor_pin may not be needed. :::

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

:::caution To prevent damaging your device, double check your device's schematics before attaching to the GPIO pins and setting this value. :::

Details

Hardware

The sensors can be wired differently, here's one example for sensor DS18B20.

Known Problems

  • No default configuration values are currently set, so this must be done when enabling the module.
