Overview
An older home's hallway or bedroom wall box without a neutral wire can take this Cync smart switch, which replaces a standard single-pole switch. It joins home WiFi for app schedules and voice control, with a push button and light ring on the face.
Skipping the neutral requirement opens smart control to many older boxes that would otherwise need rewiring. A ground wire is still mandatory, three-way setups are not supported, and homes built before the eighties should check bulb compatibility.
Who it's for
Homeowners and renters with permission can add schedules and voice control to existing bulbs without a hub. Stairways and long halls controlled from two switches need a different product.
Pros and cons
- No neutral wire needed
- No hub or bridge required
- Works with existing bulbs
- Schedules from the Cync app
- Ground wire required
- No three-way support
- WiFi limited to 2.4 GHz
- Some bulbs may need checking
Performance notes
Without a neutral, the switch draws its standby power through the bulb circuit, which is why bulb compatibility matters in older homes. Response to app and voice commands depends on a stable WiFi signal on the older band at the wall box.
