I want to create a subflow and have the question if it is possible to disable the input or output?
If you take a look at the email-node, there it's possible to change the mailreceiving from seconds to "if triggered". Then an input appears. Is this behaviour also possible with subflows?
If you don't want the subflow to have any inputs then set the input count to zero. Perhaps, however, I misunderstand the question. If so then please try to explain in more detail.
I want to use a subflow for switching on and off lights and other switches. For switching, I need an output, but for setting the correct state to the dashboard switch, I also need an input. But I don't want to make two subflows. So the subflow must have both (input and output), but I never need both at the same time.
Just take a look at the email node as I desribed in my initial post, the the input can be enabled.
