Practical use cases
- Allows a classic wall switch to be used alongside a smart bulb, without the bulb being disconnected from the WiFi network when the power is physically cut.
- Useful when you want to keep an existing switch but also control the bulb from the app or by voice, without the risk of it dropping off the network after an accidental switch-off.
- Available in 1- or 4-channel versions, for installations with one or more independently controlled lighting points.
- Recommended especially when installing smart bulbs in homes with traditional switches and no neutral wire available.
