Hydreon Rain Sensor

The hydreon_rgxx sensor platform allows you to use rain sensors by Hydreon. Currently supported are the RG-9 and RG-15 sensors (model comparison).

These optical rain sensors use a UART connection at 3.3V. The UART is required to be set up in your configuration for this sensor to work.

Supported firmware versions:

RG-15: v1.000
RG-9: v1.000, v1.100, v1.200

    resolution: high
    acc:
      name: Rain
    event_acc:
      name: Rain Event"
    total_acc:
      name: Rain Total"
    r_int:
      name: Rain Intensity

Configuration variables

model (Required, string): Specify which rain sensor you have connected. Must be either RG_9 or RG_15.
disable_led (Optional): Disables the on-board LED. Defaults to false. Only on RG-9 firmware version 1.200-onwards.
uart_id (Optional, ID): Manually specify the ID of the UART Component if you want to use multiple UART buses.
moisture (Optional): Rain intensity level from 0-7 (more detail). Only on RG-9.
- All options from Sensor.
temperature (Optional): Device internal temperature in Celsius. Accuracy is ±5°C. Only on RG-9 firmware version 1.100-onwards.
- All options from Sensor.
resolution (Optional, string): Specify rain sensor resolution. Must be either low or high. Default resolution is high. Only applies to RG-15.
acc (Optional): Amount of rain since last message (see update_interval ), in mm. Only on RG-15.
- All options from Sensor.
event_acc (Optional): Amount of rain for this event (i.e. since it last stopped raining), in mm. Only on RG-15.
- All options from Sensor.
total_acc (Optional): Total amount of rain this sensor has ever measured, in mm. Only on RG-15.
- All options from Sensor.
r_int (Optional): Current rain intensity in mm/h. Only on RG-15.
- All options from Sensor.
update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.
