Strange things always seem to happen when i'm using 1-wire...
I added an extra Temperature sensor to my HA7Net yesterday, to measure the temperatures of the water used for heating.
But i get some strange results. Here's what i mean:

I keep getting these odd 85 degrees readings.
I'm using a DS1820, power supplied by the Ha7Net, checked at 4.98 V, using firmware version 1.0.0.16.
Even the web-interface gives me the "85" readings, so i'm not doing anything wrong in my software.
What could be wrong here?
