A Light Controlled from Two Places Needs a Matched Smart-Switch Plan
For a hallway or staircase, buy the multi-location arrangement rather than one isolated switch. The correct companion or approved wiring method depends on the exact control family.

Count the existing positions
Mark every place that currently operates the circuit and which positions need dimming. That simple sketch helps prevent a quote covering one attractive switch while leaving a second location unresolved.
Match the companion
Use the manufacturer’s approved companion, remote or documented switch arrangement. Products described as three-way do not necessarily share the same installation method, even when their wall plates look similar.
Compare the finished wall
Include companion devices, plates, adapters and electrical labor in the proposal. Ask to see the final on/off and dimming routine at each position before approving a room-wide order.
