I just noticed this button type that does almost what I need, just that I absolutely don't want to have Ch1&Ch2 be both on.
Cycle Switch - At the push of a button, the sequence is: Ch1-On Ch-2-Off, Ch1-Off Ch-On, Ch1 & Ch2 On, Ch1 & Ch2 Off.

Hi all,
After a few basic shelly introductions at my home, I'm trying to tackle a more complex scenario.
I want to automate my ventilation system which currently can be set to 3 levels with a rotary switch. End goal is having it react on CO2-levels in my house and hopefully be more energy efficient. On the support page of Zehnder I found this simple diagram how it is wired. Nothing fancy, see below. The point is that brown is either not bridged or only bridged to gray or black, but never to both of them at the same time. I'm not sure what would happen if I did, but let's say I have no intention to find out the hard way.
The second image comes from the same support page where they give an example of how to wire it to a Niko Home control system. Seeing that, my reflex was I could use a Shelly 2.5 for this. Only difference is that I would still use the rotary knob in place and have it connected to the SW1 and SW2 inputs. If I'm not mistaken, that's the way to go.
BUT.. I want to avoid both that of the outputs are ON at the same time. Can this be done? Can I make the 2.5 behave mutual exclusive? Are there any pre-event-hooks I can hook in to, to make sure the other output is definitely out before switching the new one on?
Or should I go the Scene route (which I haven't used so far..) ? But my fear is that it will be switched on first before I can turn the other one off.
