In scence conditions, we can assign a device to be a tricker and one or more devices to perform actions. Unfortunately several Sonoff models can not be tricked themselves. For example, ch1 of Sonoff 4ch Pro can not trick ch2 since it is the same device. However, Sonoff Dual claimed to be equals to 2 Sonoff basic switches! Sine I have no Sonoff Dual on hand, anyone can tell me if I can set a channel of Sonoff Dual to be a tricker and another one to perform an action.
