Roller shutter control via Shelly 2.5, any experience?

You don't lose anything at all, and even gain the option to fully close without having to stand there.

Did I misunderstand or did you? I thought with push buttons you give one impulse and the shutter starts moving without having to keep the button pressed?!

Thank you very much in advance for the active participation. I have also already thought of low doses for this reason, but the objection about buttons instead of switches is good so that they are not in confusing positions

Another advantage of push buttons: you can distinguish between short press, long press, and holding down.

edit: We have 2 switches per roller shutter. Unfortunately, I don't know how it looks with a rocker switch.

It looks the same. Push buttons also have a rocker switch for up and down on special request, but they do not stay in the position. Or you can use a push button with two contact points (up and down on one rocker). In general, push buttons, as others have also written, have only advantages.

Of course, you don't have to keep standing at the push button. The button sends an impulse to the Shelly and it then moves the roller shutter completely. It's good that here people with switches give wrong information about push buttons *shaking head*

of course you don't have to stop at push buttons. The push button sends an impulse to the Shelly, and it then fully operates the shutter.

What the Shelly does with the push button's impulse is not really a property of the push button itself, so there was no wrong info given about push buttons.
But it's true, of course, I didn't have the setting option in mind. So then there's no difference (except in the specific operation) between push button/switch when used with the Shelly, right?
