That would still be pretty useless since electronics usually have to be very accurate. Heating WIFI by an arbitrary amount would screw up almost any counter/calculator/computer in TPT. It would be much easier to turn switches on or off to control WIFI and PRT channels.
What is so honestly hard about heating WIFI, PTRO and PTRI that you need to create another element with exactly the same purpose with a different method to create such a result?
If you're trying to make a WIFI that will spark to different outputs depending on temperature that changes without using the HEAT/COOL tool, there are other ways without creating a new element.
