How old is your emonPi?

Pin 3 is Gnd only on the early models, on the later models Pin 3 is open-circuit, for consistency you should probably stick to using pin 5 of the RJ45 as Gnd.

so the temp senser may not be properly powered and not being seen by the emonPi.

Or as the pulse counting is done on pin6, if the temperature is causing a pulse count it would suggest you have connected to pin 6 not pin 4 and the 1-wire data stream is being seen as pulses.

Have you restarted the emonPi since connecting the new sensor? the emonPi only looks for devices at start-up and after that new arrivals will be ignored. You will probably need to power-cycle as rebooting the OS will not necessarily resart the emonPi add-on board.
