There are a lot lighting options in the app, although hard to see what value most of them offer, e.g. all the different themes. The time-of-day-based lighting is really useful and you should know that it works whether the light switch is on or not, i.e. if you turn the light switch on in the evening the lights will be on the evening timer setting. Local WiFi connection gives you a much faster response but, working via the mobile network is pretty good too. For me this is relevant because I have much more available data on my phone than through my home ISP.
