There is no such class as “string” or comparable. I tried state class measurement (before it was blank with same error).

The functionality works perfect and the entity displays my desired output. It is just an annoying error message.

I’m getting this exact error as well. Mine also works fine but I try to go through my errors and correct them, but there’s no option for my template sensor to indicate a string value instead of pre-determined measurements.

help please…

Remove the unit of measurement. Like the error message says, your use of a unit_of_measurement implies that the sensor should be a number, but then your state is Automatische which is not a number.

I know, but this worked for over 2 years…

I use it as a sensor to show the last sent state variable.

E.g.
High speed “sent”
Low speed “sent”

Where “sent” is the unit of measurment.

How can I get that back working?

You can’t. Recent versions are strict on unit of measurement usage. Remove the state_class and unit_of_measurement.

Perhaps try a markup card to show it how you want.

Thank you.

The only option left is to remove the class and measurement yes…
