Found a small bug in the Heteroptera Plugin by Amin Bahrami (is he even in this forum?):
The component Spatial Possibility has a small bug in that it sets input values of 0 to false, even when the randomness is set to 0 and Possibility is set to 1. You have to add something like 0.001 to all values so even the zero values stay in.
Also it would be nice if would work without the data input if I just want the boolean values.
