what is wrong concerning this Node-Red-Log:

What is the flow on that pi trying to do?

There are several functions, DoorBell (mgtt and remote-access) and garden irrigation

some other question to get a feel of what you have
1 - What version of NR and node.js (you can get this from the startup log)
2 - What OS and version are you running on the Pi?
3 - What version of MQTT are you running?
4 - what device is the MQTT broker running on?
5 - Are any Docker containers involved?
6 - Did this just start appearing?
7 - have you made any changes recently?

Hi Paul

thank you very much for your support

  1. NR vers v2.1.4 / Node.js vers: 14.19.1 / Npm 6.14.15
  2. OS Raspian Lite / Linux 5.10.103-v7+ arm LE (RPi 3 + running headless, SSH-access only)
  3. mqtt V3.1.1
  4. local, on the same RPi as NR is running
  5. none
  6. on January 2022-11 I have done a complete new installation/setup (new SD-card)
    after that I perform my last project „DoorBell“ with a IOT (ESP32-CAM) and my first encounter with MQTT
    further with new Node „node-red-contrib-remote-access Vers. 1.4.0
  • the Part „Irrigation“ is my be running now approx 7 years (same RPi) and runs very stable
  • the project „DoorBell“ isn’t finish, it still doesn't meet my expectations

Sevgilerimizle mit sonnigen Grüssen kind regards

Max, which version of mosquito have you got installed?
Do you have and debug nodes in your flow? If so, are they named?
I see ‘debug1’ in the logs and wonder if that is from a debug node you have.

mosquitto 1.5.7
yes, I have several Debug-Nodes in divers Flows, but all „closed“ until one together with the „Remote-Node“
also I observe the Debug-messages in Node-Red, but there no messages are coming
now I have named this debug-node with „Remote-Control"

Müller Max

is that Eclipse Mosquitto

yes, it is Eclipse Mosquitto
learning by doing - I get this MQTT - Broker by a tutorial as an Open Source MQTT v3.1/v3.1.1 Broker

pi@raspi01:~ $ mosquitto -v

None of those messages in the log look like node-red messages. It looks like something to do with your SSH connection(s) or network setup. Are they still showing up?

@TotallyInformation Julian, do you have any insite into what those messages in the log are?

I also think this has nothing directly to do with Node-Red - it must be by the SSH remonte-access - but in ll other system-log's on the Mac I couldn’t finde any entry's

the RPi is „headless“ so I can see the Log by Terminal-SSH-connection only

on the second RPi (also headless), I don’t have all this messages there - and it is also an SSH-connection on the same kind
