Our documentation mainly stresses no installing the switch that has the neutral wire missing, but not for bundled neutral wires. I would recommend reaching out to a trained professional in this case.

Thanks.  I have researched the potential safety issues and understand the (low) risk associated with the bundled neutral wires under specific unlikely circumstances.  Further consultation won't help assess how the TP-link hardware might react. 

I have a lot of other electronics that are performing well.  I'm assuming that if I connect the HS200 to a legiimate neutral wire and that wire happens to have a slight phantom voltage (<15V), the switch will also perform as advertised.  If you have reason to believe otherwise, please let me know.
