Hallo,  
I have a problem with the zigbee2mqtt bridge node node. It does not show any devices.  
This is the output from starting node red:

So it looks like the (2) devices are there. What must I do to get them to show up in the bridge node?  
(and to control them from node red?)  
Thanks,  
Wim

To read the device, use a MQTT-in node und put in the name of the device:

`zigbee2mqtt/0x588e81fffed11808`

Since I have set up the friendly name I can use `zigbee2mqtt/IkeaDimmer2`

Optionally you can use a JSON node to convert the output to JSON and check via debug node, which data is send by the device.

To send data to the device, use the MQTT-out node and send the data in msg.payload to

`zigbee2mqtt/IkeaBulb3/set`

(You see, I use here a friendly name, too)

Stefan,  
Thanks for your reply. I have a MQQT-in node listening to zigbee2mqtt/# but nothing arrives.  
That is why I worrie about the bridge node. It has no devices.  
"Start searching devices for 3 minutes" finds no devices.  
There must still be something I do wrong.  
Any further help / suggestions?  
Thanks,  
Wim

cflurin,  
Thanks  
I did this about a dozen times. It is not very node-red specific. (I have no yaml file)  
Any further suggestion?  
I have copied a few node red flows, but problem remains.

How did you install zigbee2mqtt? (zigbee2mqtt isn't a node-red node but an external app).  
Which zigbee adapter are you using, which zigbee firmware version?  
Which zigbee2mqtt version?

You can install zigbee2mqtt on a raspberry pi and use the node-red core mqtt nodes. (zigbee2mqtt can run on the same rpi as node-red).

To test the mqtt connection you can install the mqtt-explorer e.g. on a PC, see [http://mqtt-explorer.com/](http://mqtt-explorer.com/)

I installed node-red-contrib-zigbee and node-red-contrib-zigbee2mqtt from within node-red.  
CC2531firmware CC2531\_DEFAULT\_20190608.hex  
zigbee2mqtt 0.6.2  
I will install the mqtt explorer and report results

The option I proposed is an external app (which I'm using for months). Please read the doc:

MQTT-Explorer (0.3.5) reports no zigbee2mqtt traffic.  
I still assume the zigbee2mqtt bridge is non functional (no devices)

I briefly looed at [https://www.zigbee2mqtt.io/getting\_started/running\_zigbee2mqtt.html](https://www.zigbee2mqtt.io/getting_started/running_zigbee2mqtt.html) ]([https://www.zigbee2mqtt.io/getting\_started/running\_zigbee2mqtt.html](https://www.zigbee2mqtt.io/getting_started/running_zigbee2mqtt.html)  
Can I do this parallel to node-red on the same machine?  
How can I use this from within node-red?

I can only try to help if you read my answers.

> You can install zigbee2mqtt on a raspberry pi and use the node-red core mqtt nodes. ( **zigbee2mqtt can run on the same rpi as node-red** ).

Do you run node-red on a raspberry pi?

Yes, I have node-red and MQTT on the same Pi

In addition to what I have rirht now, I will do just that.

As you can see node-red can no longer be started.  
So I definately need help now.

Sorry, I can't help you, you need some basic knowledge.

Have a look here:

For the moment I forget about zigbee2mqtt.  
I have killed node-red, which is far worse.

I upgraded node-red and everything seems to be working.

I removed and reinstalled the node-red-contribute-zigbee node.

I removed the node-red-contribute zigbee2mqtt node.

Now I think I have it working somewhat:

</div>

And I removed (disabled) the zigbee2mqtt service outside of node-red.  
Only the node-red-contribute-zigbee seems to be working well.  
I just have to to the intergration with mqtt myself within node-red.  
And that is no problem at all.  
Thanks for all advise.
