Thread: Switch solution for bathroom light/fan/heater combo

    Switch solution for bathroom light/fan/heater combo

    Greetings all!

    I need a 3 button switch to control a bathroom fan/heater/light combo unit. New construction so I have full access to the walls, etc.

    I assume I will also need some sort of relay as well? I just need independent control of the 3 functions.

    Thanks in advance!

    Hello and welcome to the forum. In order to toggle a load on and off with the same button, you would need have a Lutron system such as RadioRA3 or HomeWorks QSX. This would allow you to use a 4 button keypad for the 3 functions plus an optional all on/all off button. The keypad would get programmed to three load controllers through the Lutron Designer PC software.

    Kyle: Thanks for your reply. Maybe I am missing something here...

    I don't need to toggle a load on and off with a single button, unless Lutron doesn't make a single switch with 3 buttons?

    I actually have this unit:Lutron Caseta L-BDGPRO2-WH - SmartBridge Pro

    Does it have RA3 capabilities? If not, can you please link me to a bridge that does? What is the part # on 4 button keypad would I need?

    FYI, I am very knowledgeable in all things Home Automation. I use Home Assistant and multiple Lutron devices.

    Thanks for your help!

    Unfortunately, Lutron does not make a 3 button switch. The only way to accomplish this is with a keypad in the systems mentioned above, or three individual Caseta switches in a three gang box.
