I've made a simple Node Flow with 5 IKEA light bulbs. Everything worked for a while but at some point the response of the bulbs became unacceptable. I updated my RPI and updated Zigbee2MQTT to the latest version. Now non of the Bulbs seam to respond anymore. Any suggestion where to look. Below is the log of Zigbee2MQTT:

Not strictly a node-red question but I believe you have set the same friendly name on 2 devices.

> YAMLException: duplicated mapping key

This is causing the zigbee2mqtt application to crash.

You will need to edit the yaml settings file & change one of the duplicate names.

I've used LAMP\_01 to LAMP\_06 as friendly names in my Yaml. I first thought the underscore was an issue so I tested it with Lamp01, Lamp02 etc... but this didn't help.

```auto
permit_join: false
mqtt:
base_topic: zigbee2mqtt
server: 'mqtt://localhost:1883'
serial:
port: /dev/ttyACM0

frontend:
 port: 8080

devices:

Did you craft that YAML manually (in a text editor)?

It is invalid  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/8/78b343adeab3d11f00233f36a05c7bc5c3df132f.png)

Your spacing is causing yaml to be invalid.

try this...

```auto
permit_join: false
mqtt:
base_topic: zigbee2mqtt
server: 'mqtt://localhost:1883'
serial:
port: /dev/ttyACM0

I actually use a function node to read and write the Yaml file.

OK, so did correct spacing fix your issue?

I used the next command to get to the Yaml file  
nano /opt/zigbee2mqtt/data/configuration.yaml

And pasted your code there. Now I'm getting this:

I assumed you had a working config and just fixed up the badly formatted YAML to make it work

> [@CarloJongen](#):
>
> `mqtt must be object`

> [@CarloJongen](#):
>
> `serial must be object`

That suggests your YAML should be...

```yaml
permit_join: false
mqtt:
  base_topic: zigbee2mqtt
  server: 'mqtt://localhost:1883'
serial:
  port: /dev/ttyACM0

frontend:
  port: 8080
  host: localhost

devices:
  '0x0c4314fffe0ba5ac':
    friendly_name: LAMP_01
  '0xb4e3f9fffef340f1':
    friendly_name: LAMP_02
  '0xb4e3f9fffed966f4':
    friendly_name: LAMP_03
  '0xb4e3f9fffef188bd':
    friendly_name: LAMP_04
  '0xb4e3f9fffeecea79':
    friendly_name: LAMP_05
  '0x0017880108193b7f':
    friendly_name: LAMP_06

```

NOTE: you state `mqtt.server` to be `'mqtt://localhost:1883'` - is the MQTT broker on the same machine as zigbee2mqtt? If not, you will need to change to the IP of the broker.

Yes it's just a RPI that has the MQTT broker installed and runs Node Red.

I removed the opt/zigbee2mqtt folder and re-installed everything again. This seems to help in a way that the Zigbee2Mqtt service keeps running. I copy pasted the correct Yaml file. And I'm now getting an Entity error that the friendly name is unknown. Do I need to repair all the lights? Since I have them in the Yaml file? Below is the log.

OK after all that and resetting one lamp it seems to work again.. I still don't understand I need to reset all the lights as it seems. Is this not fixed in the Yaml file?

One thing I've noticed now is that the Zigbee2MQTT Dashboard doesn't work anymore :-/

Try resetting the MQTT server and redeploy - in the MQTT nodes of the admin panel flow

You mean with a command node and the commands below to stop and start the Zigbee2MQTT service?

```auto
# Stopping Zigbee2MQTT
sudo systemctl stop zigbee2mqtt

# Starting Zigbee2MQTT
sudo systemctl start zigbee2mqtt

```

No, sorry I was thinking that you were referring to the Node-red flow Z2M Admin which is a Node-red version of the zigbee2MQTT frontend.

If you are talking about the zigbee2MQTT Frontend then make sure you have the relevant entries in the YAML file (with correct spacing) and then restarting zigbee2MQTT may help

```auto
frontend:
  # Optional, default 8080
  port: 8080
  # Optional, default 0.0.0.0
  host: localhost

```
