I have a 2-way switched light in my house, can I make this smart?

Yes, with the bridge you can replace the switches with retractive switches allowing a single dimmer to be controlled from two or more places. The existing wiring between the switches can be used to connect the new switches, so little or no extra wiring will be needed. You can wire as many retractive switches into the circuit as you need, and the dimmer can be controlled from any of them.
