My v2 hub arrives tomorrow and I’ve been taking a look at the wires in my wall for switches. Older house, I’ve not been in the walls myself before today, but I took a look today at one of my wall switches and it’s as follows:
Two bundles of wires coming in…
Two whites connected together.
Two blacks connected together, going to top terminal on light switch.
ONE red coming from one of the bundles, going to bottom terminal on light switch.
(no, not a three-way switch for this–one switch, one light fixture)
I’ve read several of the threads about wiring (this one being most instructive: Automated Switches: What should my wiring look like? (US Version)). Haven’t had a chance to grab the voltmeter or peek at the light fixture yet, but sounds like I should be able to connect the black and red to Line and Load, then connect the Neutral… I’m pretty sure red is going to the light (I’ll have to get up there later to check).
