Sensor with only max value (humidity)

Hi there!

I have an air temp and humidity sensor, and then an air extractor to lower down humidity.

Basically I want it to stay under 60% humidity, so I've set that as a target setpoint for the humidity sensor, and linked the powerbar plug that controls the extractor to this sensor as control downward (I've actually done an OR with programable logic to also power on extractor if cabinet air temperature is too high).

Thing is that right now.my humidity level is around 48%, which is expected in winter. But the dashboard shows the sensor in red because it's far from the target setpoint.

Is there any way to configure a sensor as lower than X is good?

Cheers,
