I have an RPi running Node-Red, Mosquitto and Zigbee2MQTT in Docker (latest). Currently only one Philps Hue lamp (9290022169) is connected which I can control. Unfortunately I have a problem querying the status and use it (show in debug) in Node-Red.

This is my FLow:

I cann see the respone in the Z2M Log:

How can i read the respone in Node-Red?

Thanks and have a nice day,  
Ben

Hi Ben,

 ![Capture](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/a/0/a0f4517eabcd603cbd657d255c7575c1ee9219e8.png)

This should be enough to get the status out of your lamp after pressing the **statusabfrage** , don't forget to set the output of the mqtt node to "a parsed json object" for easy handling of the data.

Hi edje,

Thanks for your reply.

Unfortunately I don’t get a response in Node-red.

Here are the settings of the mqtt-in Node.

Do you think these settings should work?

If you install MQTT explorer you can watch and examine all the MQTT topics flying around & determine what topics you need to subscribe to

The mqtt **in** node must be without the **/get** in the topic.  
So the topic needs to be **zigbee2mqtt/Lampe\_Buero**

I tried this before. But with no succes.

If I got that right, it should actually work with this flow?! But I did not receive the response of the bulb in Node Red (but in the MQTT-Broker Logs).

Do you have any ideas how I can catch the respone in NodeRed?

This is my Flow:

It looks good, now set the output of the mqtt node to **a parsed json object** and look again in the debug window.  
To be sure you don't miss anything set the output of the debug node to **complete msg object**.
