@cabat Thank you! Apparently, the MySensors sketch supplied in the Build section is not written to work with HA. I did take a stab at it and pop some code in the loop section, and the sensor now shows up but is not functional. I will have to dig more and determine what should be added to the sketch for it to work.
Thanks much for the pointer.
I have the following relay device that shows up in the .json file of HA, but will not appear on the dashboard as an available device. Guessing it doesn't like something about the sketch, but not sure what that might be.

@mfalkvidd I was looking at it through the perspective of my 8 channel relay which needs an external power source to work reliably. Seems 6 moisture sensors will work fine.
@mrhutchinsonmn Did some more research. It seems it is possible to run all 6 sensors on a single board without a 2nd power source since readings are not taken simultaneously. Is that a correct assertation?
I want to run 6 analog moisture sensors on a single arduino nano(if possible). I am guessing that may cause erratic behavior from power issues. Is there a way to use an external power source and still provide a connection to the nano, like is done with a jd-vcc pin on my 8 channel relay, so the sensor will work correctly?
Is there a way to contribute to mysensors tutorials, example sketches, etc? In my experience, I have found some tutorials to be limited, vague, or missing information that would be helpful to a novice, such as myself. For example: currently, I am learning RS485 and have a working moisture sensor sketch I would like to contribute that may be helpful to someone else. Is there a corner for such contributions?
@electrik Yes... that worked!!! Moved node and child id above mysensors.h
Thank you!!!!
Thank you for the advice!
I started over, just to be sure I didn't have anymore mix ups, but still have not been able to get the RS485 motion sensor and RS485 gateway to talk.

Ideas?
@mfalkvidd Ugh!!! Too many versions of the sketch :)... Had to switch between my laptop and pc because of sketch upload issues.... Must have grabbed an old sketch.. I HAD commented hwserial out earlier... Getting communication now but not a valid message, not enough values to unpack errors. I will dig into that tomorrow. Thank you!!!
@mrhutchinsonmn Might have confused the issue with my reply.. Neither 115200 nor 9600 baud rates resolve the communication issue.
@mrhutchinsonmn said in Motion Sensor not presenting to RS485 Gateway / TSM:FPAR:NO REPLY:
9600
Good catch.. That was an old version... both are set to 115200 after 9600 did not work
Hardware: Arduino nano boards+ RS485 devices with separate 5 volt power supply
I am trying to set up my 1st Rs485 gateway motion sensor on Home Assistant, per the following tutorial:
https://www.mysensors.org/build/rs485
The motion sensor is not presenting itself to the gateway, so I did some digging and found this thread on the subject:
https://forum.mysensors.org/topic/11048/mqtt-ethernet-gateway-with-wired-rs485-network.
I have things wired up as per this pic provided in the tutorial
Although I am not using mqtt, everything seemed to be pertinent but I was still unable to get communication between the sensor and gateway.
Ha logs show the gateway seems to be happy:

bool tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH;
Serial.println(tripped);
send(msg.set(tripped?"1":"0")); // Send tripped value to gw
// Sleep until interrupt comes in on motion sensor. Send update every two minute.
sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), CHANGE, SLEEP_TIME);
}
To rule out hardware failure, I followed this tutorial, and all works as expected:

Transmitter sketch:
const int ledPin = 13; // Built-in LED
const int EnTxPin = 2; // HIGH:Transmitter, LOW:Receiver
void setup()
{
Serial.begin(9600);
Serial.setTimeout(100);
pinMode(ledPin, OUTPUT);
pinMode(EnTxPin, OUTPUT);
digitalWrite(ledPin, LOW);
digitalWrite(EnTxPin, HIGH);
}
void loop()
{
int rdata = analogRead(0); //data from potentiometer
int angle= map(rdata, 0, 1023, 0, 180);
//transmitter data packet
Serial.print("I"); //initiate data packet
Serial.print("S"); //code for servo
Serial.print(angle); //servo angle data
Serial.print("F"); //finish data packet
delay(50);
//receiver data packet
Serial.print("I"); //initiate data packet
Serial.print("L"); //code for sensor
Serial.print("F"); //finish data packet
Serial.flush();
digitalWrite(EnTxPin, LOW); //RS485 as receiver
if(Serial.find("i"))
{
int data=Serial.parseInt();
if(Serial.read()=='f') //finish reading
{
onLED(data);
}
}
digitalWrite(EnTxPin, HIGH); //RS485 as transmitter
}
void onLED(int data)
{
if(data>500)
digitalWrite(ledPin, HIGH);
else
digitalWrite(ledPin, LOW);
}
Reciever sketch:
#include <Servo.h>
Servo myservo;
const int EnTxPin = 2;
void setup () {
Serial.begin (9600);
myservo.attach (9);
pinMode(EnTxPin, OUTPUT );
digitalWrite (EnTxPin, LOW );
}
void loop (){
if ( Serial.available ()){
if ( Serial.read () == 'I' ){
char function = Serial.read ();
if (function == 'S' ){
int angle = Serial.parseInt ();
if ( Serial.read () == 'F' ){
if (angle <= 180) {
myservo.write (angle);
}
}
}
else if (function == 'L' ){
if ( Serial.read () == 'F' ){
int val = analogRead (0);
digitalWrite (EnTxPin, HIGH ); //enable to transmit
Serial.print ( "i" );
Serial.print (val);
Serial.println ( "f" );
Serial.flush ();
digitalWrite (EnTxPin, LOW ); //enable to receive
}
}
}
}
delay (10);
}
Any ideas about what might be causing the issue?
I am considering moving away from using nrf24l01 for my garden automation system and implementing an RS485 solution instead. However, I am not clear if I can run my 8 channel relay via a single RS485 module as I currently do with nrf24l01, or if each channel needs a single RS485 module. (have not worked with RS485 yet)..
That worked for me. Thank you!
The sketch looks like this now but does not work with gateway sketch (below). Is that related to code in the mysensors.h library, or do I need to make a change in the serial gateway sketch?

I have set all my sensors up using a nano and nrf24l01 wireless modules. Just received some rf-nanos I ordered but they are not working with my current sketches. I could use some advice on what to change in my moisture sensor sketch to get it to send data to my gateway. I verified the new rf-nanos work with the following 2 sketches.
