@grumpazoid if you haven't already, check the section on presentation and sending data in the api documentation.

@skywatch I beleive the change refers to https://github.com/mysensors/MySensors/issues/1123

When you compiled, you should have gotten this warning:

MY_RADIO_NRF24 is deprecated, use MY_RADIO_RF24 instead.

Did you not get that?

@grumpazoid the debug output from the node will show what the node is sending. From that it should be easy to determine if it is a sketch problem or a Domoticz problem.

@skywatch I don’t know but I’ll try to find out when I have access to a computer. (currently traveling)

@grumpazoid no you'll need to recompile Domoticz

As an early holiday gift, MySensors 2.3.1 has been released.

Highlights
RF24: Add delay after power-up
RFM69 frequency band support for India
Improve transport function & debug messages
Allow flash strings in present() to save RAM

Release notes and changelog: https://github.com/mysensors/MySensors/releases/tag/2.3.1

Important information:

• The NRF24 defines have been renamed to RF24 to use naming that's consistent with the other transport defines.
• ESP8266 board definitions 2.4.2 or later are REQUIRED for use with this release. If you use ESP8266 board definitions 2.4.1 or earlier you will get an error saying fatal error: gdb_hooks.h: No such file or directory #include "gdb_hooks.h"

Welcome to the forum @asalas

st=NACK and the exclamation mark in

DEBUG !TSF:MSG:SEND,0-0-164-164,s=1,c=1,t=2,pt=0,l=1,sg=0,ft=0,st=NACK:1

indicates that the gateway does not receive acknowledgement that the node received the message. You can use the log parser to help understand the log.

The reason the node does not receive the message is that he node is sleeping. When a node is sleeping, it can not receive messages.

The easiest way in you case is to remove the sleep() line and add an if clause to only send a message if tripped changes value.

@grumpazoid I'd say operator error if you connected the power supply incorrectly, faulty board if you connected the power supply correctly

@bearwithbeard I don’t know much about pcb design but the serial header could be useful when debugging/troubleshooting so personally I would prefer that at least the tx pin is available. Some people have used pogo pin connectors to save space.

@jhussain downgrading the esp8266 board files to version 2.4.1 did not help?
