Hi - I recently purchased a home that is primarily low voltage wiring and push button Remcon switches and relays. The relays are distributed around the house at each fixture. Since all of the lighting receptacles, switches, and relays are very old, I'm trying to figure out what my options are for updating this system? The house is quite large, and replacing all of the electric with standard wiring would be a massive effort that I would prefer to avoid. Any information, suggestions, etc... would be appreciated. Thank you in advance.
