Issue: Currently, when adding a scene, for example: a Sonoff TX3 device (3-gang switch), it is not possible to assign CH3 to trigger CH1 and/or CH2 (within the same device). The device is only able to perform a trigger on other devices.
Proposed: To allow performing a trigger on itself, for example, on the same Sonoff TX3, assign CH3:ON = CH1:ON and CH2:ON and CH3:OFF = CH1:OFF and CH2:OFF
Why this is needed?
To allow single switching that does multiple actions, for example, CH3 to turn on/off multiple devices (including devices it owns which are physically wired on CH1 and/or CH2.
