:description: Instructions for setting up TX20/TX23 wind speed and direction sensors

|
The ``tx20`` sensor platform allows you to use your TX20/TX23
|
|
wind direction and speed sensors with ESPHome.
|
|
The only required pin is the black or brown cable (which is used to transmit data.)
|
|
The red cable should be connected to VCC (3.3V), green initiates the data transfer when connected to GND
|
|
and should therefore be directly connected to GND and the yellow cable should be always connected to ground.
|
|
The difference from the TX20 to the TX23 seems to be that the green cable does not matter any more and the
|
|
wind sensor is just sending a datagram every 2 seconds - pretty much the same as when the green cable was
|
|
connected to GND in the TX20.

# Example configuration entry
|
|
sensor:
|
|
- platform: tx20
|
|
wind_speed:
|
|
name: Wind speed
|
|
wind_direction_degrees:
|
|
name: Wind direction degrees
|
|
pin:
|
|
number: GPIOXX
|
|
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **wind_speed** (**Required**): The information for the wind speed sensor.
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **wind_direction_degrees** (**Required**): The information for the direction
|
|
in degrees sensor.
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **pin** (**Required**, :ref:`config-pin`): The pin, where the black or brown
|
|
cable are connected.
|
|
|
|
.. note::
|
|
|
|
In order to create a text sensor to show the textual representation of the wind direction
|
|
the following config can be used. "tx20_id" needs to be replaced with the id of the TX20 sensor (**not** with the id of the subsensors).
|
|
|
|
.. code-block:: yaml
|
|
|
|
text_sensor:
|
|
- platform: template
|
|
name: "Textual Representation Wind Direction"
|
|
lambda: |-
|
|
return {id(tx20_id).get_wind_cardinal_direction()};
|
|
update_interval: 2s
|
|
|
|
.. note::
|
|
|
|
It appears that the manufacturer discontinued production of this sensor, as it doesn't seem to be available anymore for purchase.
|
|
There are various alternatives though, and since ESPHome has a :doc:`/components/modbus`, any model supporting RS485 connection
|
|
can be easily integrated.
|
|
|
|
Check out in the ESPHome Devices database example configurations for
|
|
`RS-FSJT-N01 Wind Speed <https://devices.esphome.io/devices/Renke-RS-FSJT-N01-Wind-Speed>`__ and
|
|
`RS-FXJT-N01 Wind Direction <https://devices.esphome.io/devices/Renke-RS-FXJT-N01-Wind-Direction>`__ sensors.
