This is what I did pulled updates & upgrade(after hari's changes).
Delete exiting 1wire child if have one, create new 1wire child (used wizard).
Went into template and changed: Comm Method was saying 'RS232' so changed to 'Please select'
Under Device data - 37 com port on pc (string) - Default value - was still saying 'dev/ttyS0' so just deleted value and saved template
installing new software message.......wait to finished message
check 1wire says registered.
Plugged in sensor......new software message........finished install message
back to web-admin child sensor of 1 wire created and showing temp
selected what room sensor is in + gave it a individual name
now shows under climate-floorplan.
