|
This plugin requires attaching a peripheral accessory to your device. It will not work without one.
|
|
:::
|
|
|
|
## Overview
|
|
|
|
The Environment Measurement Plugin will allow nodes to send a specific message with information from connected environmental sensors. Currently supported sensors are BME280, BME680, DHT11, DHT12, DHT21, DHT22 and Dallas 1-wire DS18B20.
|
|
|
|
:::tip
|
|
Once plugin settings are changed, a **reset** is required for them to take effect.

### 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
|

The preferred setup is using I2C, so the `environmental_measurement_plugin_sensor_pin` may not be needed.

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

## Details
|
|
|
|
### Hardware
|
|
|
|
The sensors can be wired differently, here's [one example](https://randomnerdtutorials.com/esp32-ds18b20-temperature-arduino-ide) for sensor DS18B20.
|
|
|
|
### Known Problems
|
|
|
|
* No default configuration values are currently set, so this must be done when enabling the plugin.
