ranker,

I have the bigNG, sensorbus and those exact temp probes from PPCs and have not had any problems.

From the tone of your message, they worked for a while and then stopped?

Not sure what to tell you. How many of these have you tried? Did you try to put it on your BigNG directly or only on the sensorbus?

Could always try this:
