Radiotherm Integration add 0.5 degree temperature setting

Current Radiotherm integration shows the current temperature with a 0.5 degree resolution but you can only set the temp to a full degree. The thermostats own app as well as the device itself lets you set it to 0.5 degree resolution. Can that be changed?
