The company Feller sells a wall mountable ‘Smart Light Control’: this provides 4 push buttons compatible with the Philips Hue system (on, off, dimming, etc). Unlike many other remote controls and buttons it is a great design and available in different colors. Feller does have a ‘classic’ wall switch series too, so this one is perfect to replace or augment an existing installation and make it ‘smart’.

Philips Hue Smart LED stripes are great, but they have a disadvantage: the LED density is rather low: one LED cluster (WW, RGB, CW) every 55 mm. This leads to the problem that individual dots might be visible if the LED stripe is directly visible. Even if the LED stripe is used for indirect ambient light it means that individual dots might still be visible on the wall or ceiling. The solution is to create a ‘high density’ Hue smart LED stripe:
