In the ewelink app for ios and android, you can independently turn on / off each of the two connected devices. But the button on the double sonoff is not an on / off switch, it is only for long press to enter the wifi pairing state. You can set single / repeat / countdown time schedules to turn on / off at a specified time, share to others so they can control together.
