The Sonoff switch has one channel and features a modern design and wireless operation. The remote control feature increases the convenience of use.
For convenience, you can control the switch using the eWeLink app, which is compatible with Android or iOS. The switch also supports voice functions with Amazon Alexa and Google Assistant. With this solution, you don't even have to get up from the couch to turn off the lights. The switch accepts the 433MHz RF protocol, which is compatible with Sonoff devices, so you can use it as a remote control.
