I want to install a three way switch. I do not ever need to use one of the two switches, so I do not need to install the Pico remote. My question is can I leave the already installed switch as is and just not use it or do I have to remove it and cap off the wires as instructed in the three way installation Caseta-Pico video on YouTube.I am electrically dumb but I have installed Lutron dimmers and feel this is within my capabilities if I get an answer to this question. Thank you.
