HS200 smart switch not working
I purchase a 3 pack single pole Kasa smart switch on Amazon and hired a licensed electrician to install the 3 switches. The other 2 works as expected, except for 1 switch, which is connected to wifi and set schedule, but the 2 outside lights that originally connected to this switch will not turn on. When I hit the on/off on my iphone, the lights make a respond noise, but no lights come on. Before this, these 2 lights were on a dumb switch and were working fine.
Please help. This was installed by a licensed electrician.
