App can’t currently graph “third channel”, only those two real ones..*

If you log internal temperature and K-type probe voltage, you could (in theory, if you have too much free time and great skills in maths) calculate and graph probe temperatures with excel etc, but it really is pain in the ass to even understand what the hell k-type probe is and what and why it does :D

There has been head scratching threads on this forum couple times, so you might want to try search for “k-type” or something..

* – I’m not a coder, but i really think that “third channel” graphing would be quite simple thing to implement..
