The ``kuntze`` component allows you to integrate the Kuntze water measurement
|
|
instrument in ESPHome. It uses :ref:`UART <uart>` (ModBUS) for communication.
|
|
|
|
Once configured you can use sensors as described below for your projects.

Kuntze Neon® Multi instrument
|
|
|
|
Overview
|
|
--------
|
|
|
|
Kuntze devices have an RS485 (ModBUS RTU) communication port. Please see the
|
|
Kuntze papers for the pinout of the RS485 connector on your unit. ModBUS line
|
|
has to be terminated properly (with a ``120Ω`` resistor), and since this is likely
|
|
your only unit connected to ESPHome, you should activate bus termination in the
|
|
Network menu (this component doesn't support multiple Kuntze devices on the same
|
|
bus). ModBUS address should remain at factory default value.
|
|
|
|
The device communicates at ``19200`` baud ``8E1``. To connect to ESPHome, an RS485
|
|
transceiver is needed. Choose a type which does not need a trigger to send and
|
|
receive data, for example:
|
|
|
|
.. figure:: ../../images/rs485.jpg
|
|
|
|
The controller connects to the UART of the MCU. For ESP32 GPIO `16` to `TXD` and `17`
|
|
to RXD are the default ones but any other pins can be used as well. 3.3V to VCC and GND to GND.
|
|
|
|
.. warning::
|
|
|
|
If you are using the :ref:`logger` make sure you are not using the same pins for it or otherwise disable the UART
|
|
logging with the ``baud_rate: 0`` option.
|
|
|
|
Component
|
|
---------
|
|
|
|
A configured modbus component is optional. It will be automatically created.
