The dimmer switches are better than the tap. They do 5 scenes and dim and come off the bracket to use as a remote. Only £20 too.Got to say after 3 years of having my hue lights I am still very impressed. Out of 8 Iris' 5 blooms and 4 of the dish shaped ones non of them have broken, they work just as well as the day I bought them. I use them at least 8 hours a day too.
There are some cool things you can do with them. I use IFTTT to interface with them too which means I can get one or two of the lights to blink once when the boiler starts and stops (linked to nest). One light blinks red 5 times when the wifes phone is within 500m. The entrance lights turn on when I am close to home at night. I have profiles set up for watching films, white light, sunset light and a profile for when I am away that keeps one or two lights on randomly to make it look like someone is home.
I have the tap remote in the lounge to turn the lights on and off - its a bit limited in functionality and wouldnt mind a more advanced remote.
Alexa is fairly good, dont use it for the lights that much but its useful to tell her to turn the heating temperature up to 23 or whatever.
