Opentherm setpoint values incorrectly showing up as 16.9, 17.9, 18.9

Hello,

See attached screenshot. In Home Assistant, whenever I set a certain setpoint temperature for my heating (shown here in small font size in orange), I set them to rounded values like 17.0 degrees, 18.0 degrees, 19.0 degrees.

However, after doing this, Home Assistant will display the value (incorrectly) as 16.9, 17.9, 18.9 and so forth.

This happens when I set it both on Home Assistant and the thermostat itself.

Is there a way to fix this? I think that a simple rounding function would fix most cases.
