I installed a HS200-2 replacing my 2 switches on my wall. Each of the switches control individual lights. 

Switch (1 - Left) - Controls a ceiling light and works perfectly.

Switch (2 - Right) - Controls 3 cieling lights that are also controlled by another switch upstairs. Below is my connection

• 1 Red (From the box) to Black (on the Kasa Switch)
• 2 Blacks (From the box) to Black (on the Kasa Switch)
• Ground (Bare wire from the box) to Green (on the Kasa Switch) 
• White (From the box) to White (on the Kasa Switch) 

The Kasa Switch 2 worked perfectly after the setup. Then when I tried to turn off the upstair switch that also controls the same set of ceiling lights that the Kasa Switch (2) does then it didn't work.

Please suggest the changes I should make to fix this problem.
