Hello,  
I get the following value from an MQTT server via # from which I want to transfer the temperature in Celsius to a msg.payload and then display it later.  
How do I get the value?

This is the return of the Mqtt request in the debug Window:

fbtemp/status/temperature:0 : msg.payload : Object  
{ id: 0, tC: 26.6, tF: 79.9 }

Thanks for help

In a change node  
set `msg.` `payload`  
to `msg.` `payload.tC`

But you may not need to move it to payload, all depends where you want to display it.
