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

Configuration variables:¶
model (Required, string): Specify which rain sensor you have connected. Must be either
RG_9
orRG_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
orhigh
. Default resolution ishigh
. Only applies to RG-15.acc (Optional): Amount of rain since last message (see
update_interval
), inmm
. 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
.
