I don't know what these cost, the article didn't say,but I run Hue throughout my home. If I was to take just the absolute minimum you'd require for sleep/wake, and getting to the bathroom at night; 1 bulb in a lamp in your bedroom, 1 on the landing and 1 in the bathroom, add 2 Hue motion sensors (or just one if your can live with it turning both the landing and bathroom lights on) and the hub, you're looking at 1 Hue Starter kit and 2 sensors, in an Amazon sale you could do that for around £150, or closer to £200 if not. This is for the colour and white ambiance bulbs, which do full colour and a broad spectrum of white. Now you have your colour temps for sleep wake, as well as any colours you desire for the landing/hall and bathroom. You have hands free lighting from room to bathroom at night, and can pre configure different light temps, colours and brightness for day/night and can set sleep/wake schedules, sleep timers and various other bits (all without connecting the hub or your phone to their cloud service); if you want some physical control the battery powered dimmer switch can be had for ~£20. I've been running this for a couple of years now since buying my new home, being able to get up in the middle of the night, hall and bathroom lights automatically turn on to a dim red I've configured for night mode, then wonder back to bed and have them turn them selves off a couple of minutes later has been priceless. I also don't use an alarm because the bedside lamps are set for "sunrise" at my desired wake time. The sensors also sense ambient light which you can configure the level of to not activate the lights at all if the natural light level is sufficient in the day. The sensors also hide other features accessible by the (local) API that Hue don't use yet, such as temperature and Lux amongst other things. The Hue can also be extended almost limitlessly over time to (as I've done) cover your whole home (and outside it with their outdoor lighting). The question now is, how close in price is that minimal scenario to what these cost Casper lights cost?
