I was about to say something like "oh those smart devices, what if the power goes down?" then caught myself.



Hehe.

Seriously, though, with smart lights you probably do actually want to consider what happens when the power goes down, or more precisely when the power comes back on.

With a dumb light controlled by a dumb switch when power comes on the light goes back to the state it was in when power failed (unless you have flipped the switch while the power was out).

With smart bulbs some of them come at full brightness when power comes back (and white if they are color bulbs), regardless of what on/off, brightness, or color state that were in when power failed.

This can be irritating.

Some brands let you set the default power on action, ideally letting you chose between off, on in whatever state they were in before lower was lost, or on in a specific state you specify.


Hue is configurable, which is what you want if some of the bulbs are hard switched (so you want them on when power is restored) or soft switched (off or last state on power restored).

Power outages are rare, though; I've not bothered configuring the soft-switched bulbs.
