Currently, brightness control of the Hub (I have a Hub Plus) is severely limited. I actually think the glow-cloud makes for an adorable sculpture, a tribute to my internet nerd roots, and I love displaying it as a centerpiece in my living room. But: the advertised “night light” benefit just doesn’t become workable without two key enhancements:
1. Changing the brightness of “rainbow mode,” not just single solid colors. I can find no way to do this. I love the spinning rainbow. It is mesmerizing and one of the Hub’s signature features, but I can’t leave it on if I can never dim how bright it is for darkened rooms or night.
2. Some way to automate the brightness of the Hub. This could be as simple as timers to dim it at night, but my ideal would be letting me hook it up to some kind of ambient light sensor or control the brightness of the light via IFTTT rules.
For me, 1 is most important. But 2 is necessary as well.
