I second this... even with the 10% brightness it's still too bright for us to sleep with our bedroom door open. I cut some paper the size of the keypad button and placed it behind it so it cuts the brightness down to a manageable level (although you still get bleed through around the edge of the button)... unfortunately, this makes difficult to read during the day. Having a simple actionable item that you can trigger with the isDaylight would be awesome.
Indigo only allows dimming down to 10%, but if you use the manual dimming method, you can get all the way down to 0%. I have it set to 0% in my bedroom and it looks great at night. I, too, vote for dimming as an actionable item.
