@hek That was it. Got node registered after clearing with 0xff.
Thanks a lot!

@AWI If node requests time and values before going to sleep, it will receive them upon return from smartSleep?

void loop()
{
  requestTime();
  request(1, V_STATUS); 
  request(2, V_STATUS);
  smartSleep(200);
}

void receive(const MyMessage &message)
{
...
}

void receiveTime(unsigned long ts)
{
...
}

@AWI If there is no RTC, should I opt to use requestTime() and receiveTime()?

I am trying to calculate time interval by calling millis() function in loop().
Looks like returned values are affected by smartSleep(). I mean time doesn't grow much during sleep.
Is there a more reliable way to detect timeout?

@mfalkvidd I added

#if MY_NODE_ID==255
#error MY_NODE_ID==255
#endif

And compiler reported

dummy_mysensor:16: error: #error MY_NODE_ID==255
 #error MY_NODE_ID==255
  ^
exit status 1

So MY_NODE_ID is 255.

Yes, I cleared EEPROM as well.

Setup:

• Raspberry Pi serial gateway.
• Node on Arduino Nano. Bare minimum code.

Problem:
Node fails to register when neither NODE_ID or MY_NODE_ID defined. It registers fine when MY_NODE_ID defined explicitly.

Sketch:

#define MY_RADIO_NRF24
#define MY_BAUD_RATE 38400
#define MY_DEBUG

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

#define SENSOR_ID 1

#define OPEN 1
#define CLOSE 0

MyMessage msg(SENSOR_ID, V_TRIPPED);

uint8_t value = OPEN;

void presentation()
{
    present(SENSOR_ID, S_DOOR);
}

void loop()
{
    value = value == OPEN ? CLOSE : OPEN;
    send(msg.set(value));
    sleep(10000);
}

What's wrong with my setup?

@dbemowsk said:

You can use that though to set the value that the node can grab. Are you wondering how to grab the value?

I am trying to figure what values to pass to
void request(uint8_t childSensorId, uint8_t variableType, uint8_t destination);
Where are the corresponding values show up in Domoticz UI?

You are pushing value from controller to the node.
But if node is sleeping, new value won't reach node.
To get new value node has to request it from controller after waking up from sleep.

The goal is to pass value to the sensor that could be sleeping. Domoticz doesn't support MySensors smart sleep mode and polling current value is only option now.

Thanks.
What if need to get value from dummy sensor controlled by Domoticz (not by another MySensors node)?
Where is corresponding childSensorId?
My RPi runs both MySensors gateway and Domoticz.
