Overall everything was fine. Setup was easy, especially since I have N wires so I didn't have to attach capacitor. Configuration was easy as Tasmota ;), with similar experience in terms of adding it to Home Assistant. One thing that I'd like to warn anyone is size of the part that goes inside the wall. In Poland at least, the hole was a little bit too small. It is round and device is more like square with rounded corners. I had to peel off part of those corners (fortunately there is enough plastic there) in order to fit it there...and it still was tight fit. ;) Also do remember that if you'll use N wire, the screw will stick a little bit which also can be a problem - I had to make small groove inside hole to make room for the screw. But still I recommend this switch and hope it will work without issues. :P
