Asking in the official app thread would help.
But since I was tagged here I’m reading along. I agree on Robert with this though. I dont want to have to add and maintain extra flow cards in the Shelly app for functionality that is already part of Homey core (and especially not just because one user does not want to pay for something 
).
My advice though, if you are serious about home automation dont go for a cloud dependent solution like Homey Cloud anyway.
But I can be persuaded if you make a donation to the plastic soap foundation though …
