I am replacing the HS200 with a dimmer switch, but there is a change in the wire setup. The HS200 had electrical wires at the bottom, so when the electrician last connected it, there was enough wiring. Now since the HS220 has connectors for the line and load wires only, the line wire is too short. I tried a butt splice to extend the wire. My switch powers and connects to the wifi correctly, but I have no power to the light at this time. Can Kasa switches be wired using a butt splice?
