Finally I found a purpose for my twatch.
I use it as a monitor for my iclesius wireless thermometer.
So I wrote a quick and dirty python script which works as a relay between the icelsius and the twatch.
The icelsius periodically broadcast the measure data to the local network.
The python script listen to the local network and capture this packet ,and then transform the packet to a format which the twatch understand.
