How to Install a Lutron Caset Smart Switch in the US If you are not comfortable handling electricity or you are not sure, hire an electrician. I'm not an electrician myself, but I feel confident enough to connect this. It's good to watch several videos for reference if you're going to try this yourself. The most challenging part with an older home is normally the space in which the switch will fit. A few solutions are:

Use wago connectors

Shorten existing wires

You can purchase an outlet extender that will help with the depth of the smart switch

worst case scenario would be replacing the wire housing box

Anyway, I hope this is informative and helps, take care and do your research.
