I guess this would do better:
s = root.find (id="*10.0*D54A9010800")*[0]*
even if only one element is returned, the find returns a list, the [0] at
the end indicate that you select the first element.
if you are interested by getting temperatures from all your ds18s20,
something like this should do:
root = Connection ("/dev/ttyD1")
for s in root.find (type="DS18S20"):
s.get("id"),
s.get("temperature")
>>> s.get("temperature")
