And as I wrote, this flow, respectively the ELSE card, makes no sense.
I just tried it with a Fibaro Wall Plug with this flow:
When…
– This flow is started
And…
– Wall Plug is turned off
Then…
– Turn off
After execution of this flow, the time stamp of the onoff capability in Developer → Devices was updated.
So the answer to your question is: Yes (with Z-Wave devices)
