Outside house lights are controlled by two 3-way switches. One is inside the house and the other in the garage. The garage switch is the normal toggle switch. But inside is this decorator sideways switch. In the two decorator switches…one is the 3-way for the outside and the other is a 2-way for the foyer.
Looking for suggestions to automate the outside lights.
For 3-way switches inside, I’ve used the Lutron Caseta dimmer switch and Pico remote. I obviously can’t fit the Caseta dimmer in this sideways setup and if I install the smart switch in the garage, the Pico doesn’t fit the sideways either.
Kasa 3 way smart switches can handle this. Install the smart switch into the garage and leave this box alone. Although they are often sold as a 2 pack, you only need one smart switch on the circuit for it to work. I’ve done this several times in my house.
