First of all, I am very satisfied with the system. But it's not quite as easy as we thought. After I've learned a lot, I have to say that Philips has not written anything wrong, but maybe I'm not the only one who falls into it on marketing. Following: 1. The lamps are not connected to the WLAN. This means that the range is not related to the WLAN, but that communicate with each other and the lamps you have to build a "lamp distance" to the most distant lamp. The range of a lamp has a radius of about 5m. 2. Lamp is not the same lamp. There are the hue bulbs that may pose various shades of white and therefore the modes Relax, concentration, activating and reading. The Friends of Hue (LivingColors Iris and Bloom) can not and the LUX can only know. Everything is okay, you just have to know which lamp you want to use for what. I would have liked a more transparent presentation of Philips. 3. the apps is not synced to my.meethue.com annoying, but I hope that is fixed this error. 4. The Oberhammer but that is not in a position to work the app via a repeater. So I'm standing next to my lamp, I can control a lamp chain, am in WLAN (via the repeater) and the app tells me she has no connection to the Bridge. Since you should quickly're working. 5. The support :) have all declared (2 times). Yes, you call me back when I can be reached tomorrow. That's now been a week. Very very bad. I hope that these teething problems are resolved soon, because the system is great. The color variations, the changing lights, the awakening of light is a very great thing.
