I have assigned ViCare Radiator Valve to the wrong room in the app. Can I move it without detaching?

In The ViCare Single Room Control solution it is possible to move the device between rooms without the necessity of detaching it. 

Just open your ViCare application, go to the room where device that needs moving was assigned to and use option “Move device to other room”. Next choose the correct room and your ViCare Smart Climate will be updated!

All detailed info can be found here: ViCare Thermostat: Operations on the device.
