For about $95 (this Pico remote PJ2-2B-GWH-L01, Caseta plastic wall plate bracket Pico-WBX-adapt, Pico cover SC-1-SW, Caseta non-dimmer switch PD-5ANS-WH-R, and rocker/toggle plate R52-80405-00W) this solved the problem of not having a second switch in the garage that my contractor didn’t do on a renovation. Very easy to install and works flawlessly. Hardest part is removing and wiring old toggle switch to Caseta switch. Hold both down buttons for 6 seconds to pair and then install remote with screws or mounting tape and you’re done. Saw it on This Old House. Perfect solution!
