WS loses direction when H/T/S sensor added to net


New Member
I recent purchased a 1-wire weather station and it works perfectly, until I add a humidity/temp/solar sensor to the net between my PC and the weather station. When I do this, I lose the wind direction; well I don't lose it, it always reports direction 16 (a direction that shouldn't be possible).
If I remove, or replace the the humidity/temp/solar with just a temperature sensor, the wind direction again is received correctly.
Any ideas what might be happening would be appreciated. I'm only using 2 devices on my 1-wire net, and they are both powered directly form my PCs serial port.
Since you are using parasitic power try removing the jumper on the H/T/S board and see if that helps.
