How to write the inputs for my topics?

We use MQTT to get our data into a influxDB.

We have the following topics:

“Car/Data/ESPActive”
“Car/Data/TCActive”
“Car/Data/Speed”

the first two topics are bool values, the last one is a float. Car/Data/ is static and doesn’t change.

Our infuxDB output works, if we use the example for cpu values as input.

So what’s you current telegraf configuration and which challenges you are experiencing?
