Hi All
Just thought i would mention that i have been working on a temp sensing probe using the Dallas 1820 temp sensor...The idea is to be able to connect a dallas ds1820 to either probe5 or probe 6 of a Probe Zone Box .

The Probe system detects if a temp sensor is connected to probe 5 or 6 on any of the 8 zones and reports the temp (currently .5 degree tolerence) via the serial interface in reponse to a status request....

Still some more testing to do as im not sure what length of cat5 this will reliably work on..But if it works it means that i can free up one cat5 cable per room which is currently used for temp sensors...as i have a probe zone box in each room at present monitoring tv,s and dvd players etc....

More Soon
