I'm trying to install a Kasa HS200 smart light switch into a box that has 2 light switches already: an exterior light and an interior light. I'd like to replace the switch for the exterior light. The house was built in 2021.
I have removed the cover and the switch I want to replace (on the left in the photo below). My question is on the neutral wiring. I see 4 white wires all joined together in some kind of connector. What's the best way for me to connect the HS200 white wire? Do I remove that connector and twist 5 wires together? I have circled the white wires in the photo below.
Edit: After doing some research maybe I just need a 5-way connector? Or cut one white wire and join with a wire nut or 3-way connector?
