While WIFI does change color when it is heated, but it doesn't change color when cooled to subzero temperatures. Not sure if this is a glitch, oversight, or intended.
Edit: The connections seem to wierd out when I try to use temperatures below -100 C since it connects to all. Not sure what I'm seeing here actually.
Oh, didn't realize it actually did change colors there, and I think you just told me the reason why it was wierding out. I thought the channels would be -273 to -200 and -199 to -100.
below -200 is currently the same as -200 to -100, i probably could make it a separate channel, but since it didn't have a full 100 degrees, i left it out. And i don't think ONE channel is that much of an improvement.
