You are right.  
So I changed the following:

And I think this is working well.

Now the gauges are showing the Right value every time.  
Cool THX a lot.

But when I connect another Sensor with the same Nodes and customized code I got an other Error and the new gauges are showing 0

"TypeError: Cannot read property 'hasOwnProperty' of undefined"  
Is it necessary to connect the 2nd switch to another Mqtt in Node or JSON node ?

No.

How are your debug nodes configured ? Set them to "complete msg object".  
What data arrives at the switch node that you get an error ?

You need an additional `switch-node` after mqtt-in/json to select your device.

You are only showing a single message, while you receive multiple. And this is a different device.

I got everything working with the hint of an additional switch-node.  
Perfect THX a lot to all who thought about my problem.
