Hey Folks! 
can I adjust the output of the sensors so that gets 1/2 degree steps like 20,5° or 21° and not 20,45° or 19.11° ?
Many Thanks for your help!
PS: Here is my actually config:
{
“id”: “temperatur-sensor1”,
“name”: “Aussentemperatur Garten”,
“class”: “DS18B20Sensor”,
“hardwareId”: “28-0000066fae4c”,
“interval”: 10000
},
{
“id”: “temperatur-sensor2”,
“name”: “Wassertemperatur Gartenteich”,
“class”: “DS18B20Sensor”,
“hardwareId”: “28-0000066fa91a”,

},
{
“id”: “temperatur-sensor3”,
“name”: “Wassertemp. Pool Vorlauf”,
“class”: “DS18B20Sensor”,
“hardwareId”: “28-03146c8e43ff”,

},
{
