Speaking of lights, and this is only tangentially smart home related, my local HDs are clearing out all of the existing Philips and Cree A19 style bulbs. I picked up four 75w equivalent Philips A19 slim style dumb bulbs for $2.90 each. I put them in a 4 to 1 bulb adapter in a big lamp connected to a GE Z-Wave plugin dimmer in a room with no overhead lighting. It’s bright as hell, it’s great.
They also had the 60w for $1.90 and the 40w for $0.90.
