Mixing temp probe brands may cause troubles.

I saw in the preset that the probe from Ikea was listed. with the low price a bought 4 of them for back up probes. I plugged one Ikea probe into my heatermeter and change the preset. It read fine but then I got some strange reading , dont remember the reading was. I found out its wire outer braid touched one of the other probe's wire braid the probes gave strange readings. I assume the probes have the polarity switched and the wire braid is not the ground. Have not confirmed this with a ohm meter yet.
 
Yup, they're wired in reverse. They also read the temperatures in a different manner using some sort of burst oscillation measurement. I should probably remove them from the preset list and just put it in the wiki, because they're not compatible with a default build. Even if you swap the polarity on the probe connectors, it is still pretty easy to get a false reading due to them shorting to something.
