Hi! Could you take a look at this Thread:

The virtual thermostats reads thermometers in each room, and can change a variable for setting the temperature in the room. This has worked flawlessly for a long time, but it seems like something has changed with a later Homey update. The temperature has been at 19 for ages, and my better half wanted to up it to 20 yesterday. We’ve done this before without any issues. The virtual thermostat basically change…

The only thing I do is make the virtual thermostat update a variable, with the built-in 0.5 increments.  
There seems like the app should have some kind of rounding enabled before setting the value, as I suddenly got a bunch of decimals when setting the temperature.
