We've done the research on this, and the answer is... It depends.
If you use Johann's code, it may be possible... You will need to really insulate the bed well as the readings could exceed what Johann uses to trigger. The problem with more insulation is that the more you place between the FSR and the bed, the less accurate your FSR's are. What fixes one problem, creates another.
If you use a trinket system... you need less insulation as the FSR's can tolerate a decent amount of heat. Is it enough? Will it cause other issues? That part we don't know yet. You will likely have to reset the FSR's once up to temp, or calibrate while cold and I would still expect to use some sort of insulation, which leads back to the insulation inducing slop.
