Works great thanks.
Except the reset pin does not work that changed

if (is_Reset = 1 )

@gohan

Should run as a server. If remote access fails.
Just needed a sketch that allowed me to control 3 different relays.
Or. As template

Wuffi0815

Can someone help me or write a sketch?
I would like to start my PC using Arduino, shutdown and reset!

On a normal PC you connect so only pin against the desired mode.
Pin 1 - mass short passage = PC starts
Pin 1 - Ground Long Pass Approx. 5sec = PC Shuts down
Pin 2 - Ground Short Circuit = PC Reset
A little I have already prepared. I have to search for everything and I do not know the language that way.
Thank you

Sorry for my bad drawing skills.

Works fine so far but the relay can not be controlled after about 30min.

Can it be that my arduino nano pro is too weak?

Thank You Is working!
From time to time you overlook small errors with great effect.

Wuffi0815

The distance is not displayed. And goes into a loop.
Sometimes I have to refresh 2-3x

no Connect: !TSF:MSG:SEND,102-103-0-0,s=1,c=1,t=35,pt=2,l=2,sg=0,ft=5,st=NACK:2457

I want to know the filling level of the tank and drive a pump.

Should everything also run in fhem.

Hello I bought a TX23 and wanted to integrate it into FHEM.
Could anyone look over the scetch if it is correct?

/**
# Arduino-LaCrosse-TX23-Library

LaCrosse TX23 is a wind speed and direction sensor. It uses 3 wires for communication and power:

Pin1 - Brown(Black) - DATA
Pin2 - Red - Vcc
Pin3 - Green - N/C
Pin4 - Yellow - GND

DATA pin is to be connected directly to one of Arduino ports.
*/

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

#include <MySensors.h>
#include <SPI.h>
#include <LaCrosse_TX23.h>

#define CHILD_ID_WIND 1

LaCrosse_TX23 anemometer = LaCrosse_TX23(4);

MyMessage msgWSpeed(CHILD_ID_WIND, V_WIND);
MyMessage msgWDirection(CHILD_ID_WIND, V_DIRECTION);
