Getting unknown value from MQTT sensor. Please help

I have setup ESPeasy on a nodemcu which provides distance data from ultrasonic sensor.

When I am able to listen to the topic.

But when I try to add it to the HA, I get error -“unknown values”
Could you please someone point, what I am doing wrong?
config.yaml attached.

Thanks

What shows the mqtt listener when you remove the # and type in the topic of your sensor?

try that:
instead of ( name : “overheadtank”)

name: overheadtank.Distance

without “” so it should work
