|
|
|
|
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 <https://rainsensors.com/products/model-comparison/>`_).
|
|
|
|
These optical rain sensors use a UART connection at 3.3V. The :ref:`UART <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`` 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*, :ref:`config-id`): Manually specify the ID of the :ref:`UART Component <uart>` if you want
|
|
to use multiple UART buses.
|
|
|
|
- **moisture** (*Optional*): Rain intensity level from 0-7 (`more detail <https://rainsensors.com/support/rg-9-rg-15-faq/#RG-9RValue>`__). Only on RG-9.
|
|
|
|
- **name** (**Required**, string): The name for the sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **temperature** (*Optional*): Device internal temperature in Celsius. Accuracy is ±5°C. Only on RG-9 firmware version 1.100-onwards.
|
|
|
|
- **name** (**Required**, string): The name for the sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **resolution** (*Optional*, string): Specify rain sensor resolution. Must be either ``low`` or ``high``. Default resolution is ``high``.
|
|
Only applies to RG-15.
