Choose a supported complete circuit arrangement after the existing wiring and loads are documented.
An older home may have several wall positions operating the same light. Replacing one plate with a smart device can affect the others, and the wiring may not match a convenient online diagram. Photograph and document the actual circuit with a qualified installer.
H2 US and Diva represent different candidate control approaches. Their model-specific wiring, load, protocol and accessory requirements must be checked independently. Do not assume that two products with similar front buttons use the same multi-way installation method or require the same controller.
Ask for a finished operation plan covering every original location. Decide which controls remain wired and which approved accessories, if any, serve another position. A clear survey can prevent a return order and preserves the everyday benefit of being able to operate the light wherever a person enters the space.
Before you order
- Identify every control on the circuit.
- Review wiring and connected fixtures.
- Specify the approved complete multi-way method.
A useful next step
Request a circuit survey and complete parts list rather than a one-device price.
