Dynamic Sensors based on object-name from MQTT

Hi,
I currently try to get all my IPMI Sensors from my Server to Home-Assistant. To do that i will use telegraf on this server and send the messages via mqtt to the ha-broker. Node-Red listens on the telegraf topic.

So my idea would be that i didn’t need to create 50+ sensors, to make a variable which covers the object-name and takes the temperature out from the message.

Hopefully its clear what i want to do.
Thanks for feedback!
