Hi, I'm a complete newbie, so please be patient, simple and explaining with your answers.
I have
RaspberryPi 2B, latest Raspbian image, Zigbee2MQTT with mosquito broker.
No security except usernames and passwords
Node-RED version: v3.0.2
Node.js version: v16.19.1
Linux 5.15.84-v7+ arm LE
I'm able to install and run Node-Red, access its web interface, download additional palletes such as node-red-contrib-zigbee2mqtt
But once I drag the "zigbee2mqtt in" node to the flow, doubleclick to configure it, enter the MQTT server address, then the node-RED crashes and keeps restarting its service. I have tried to completely remove and reinstall the node-RED packages
1. `sudo npm -g remove node-red`
2. `sudo npm -g remove node-red-admin`
3. `rm -R ~/.node-red`
then
```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
```
but when I start to configure the node, it fails again.
It is failing with these messages in the log:
```auto

Welcome to Node-RED
===================
```
This keeps repeating on and on...
I have no other flows, no other nodes in the flow.
I tried to google, ChatGPT, looking through forums but I'm too lame to figure out what is wrong and how should I fix this ☹
Thank you for your help.

On commandline:
`node-red-stop`
`node-red --safe`
Correct your flow and deploy.

Don't use the zigbee2mqtt node, as you have found, it has issues. Just use the core mqtt nodes.

I don't know WHAT to correct in my flow. The only node in the flow is the "zigbee2mqtt in" node and its only configuration is the server to which it should connect + the username and password it should use.
So what exactly should I correct on this please?

Yes, After several re-installs and hours of googling I might as well use the standard MQTT nodes....

The zigbee nodes do not offer much extra anyway.

True! Got my flow now with motion sensor, push button and a wall socket running just fine with the core MQTT nodes. Goodbye zigbee2mqtt nodes! 🤪
Thanks for your time to respond. Appreciate it!
