Questions about new installation for two smart switches at one location
I'm getting ready to purchase an install two smart switches. I've expensively botched one outlet installation 6 months ago, so I'm doing all the research up front for this.
Question 1: I have two light switches in the same box I want to replace with Kasas. Assuming the installation goes well and I install them simultaneously, when the Kasa app detects them, will I be able to tell which is which? Or do I have install one, kill the power, and then install the other?
Question 2: I've read enough now to know that neutral wires are inside the box. I've inspected the existing light switches, and see not only do they not have a neutral wire, they don't have a ground either. I do see a wing nut array of copper wires held together, so I assume those are the grounds. So, if I'm installing two kasas, can I simply bundle the two white neutral wires from the Kasa with the existing white wires ---- and the same process for the ground? or do I need to do each switch separately?
