Hi @Lambalda while checking the meaning of Yellow and Blue wire, i found some information that might help

' Yellow wires are used as switch legs to ceiling fans, structural lights, and outlets paired with light switches, while blue wires are usually used as travelers for three-or-four-way switches. '  / “Blue and yellow wires are sometimes used as hot wires,”

' Always assume that a red or orange wire (in addition to the black wire, which provides the primary phase voltage) is live. '

The Yellow/ Orange Wire from electrical box should carry power, not to the ground of HS200. 

Please check if the electrical box is a 3-way environment  (2 switches operate one light) or 2-way environment (1 switch operate one light) ?

HS200 is a  2-way switch, you will need HS210 KIT for a 3-way environment. 

Anyone who is more professional with wiring, feel free to leave your comments below, thank you.
