Question about Feller EDIZIOdue Smart Light Control for Philips Hue

The "problem" is usually that you don't just press one button, but also press a second one down at an angle. Because the switch recognises when you accidentally press both lower buttons - but as far as I know, the function is not enabled in the Hue app. You almost don't notice this, but it happens to me often. Then you think that the button press has been registered (click), but nothing happens. Make sure that you really press just the single button and not a little bit of a second one. Many people on the Internet complain about the exact problem you describe, but at least for me it's only because I don't press the button so precisely.
