Currently, my setup is...
2 Schlage Locks
MGO/Chamberlain Garage Door
23 Lutron In-Wall Dimmers
2 Lutron Lamp Dimmers
4 GE Link Bulbs
1 Leviton Appliance Module (Power on/off)
1 Leviton Lamp Dimmer
2 Phillips Hue Lightstrips
2 Pivot Power Genius
1 Nest Thermostat
4 Nest Protects
1 Wink Relay
1 Wink Spotter
I don't post it to brag, but more as an extended review. After that one month where stability was... non-existant... things are working quite well. The GE Link bulbs are all tied to Lutron on/off events and I rely on them. Occasionally there is a slightly longer delay than there should be, but 9 times out of 10 they do exactly as they should.
Currently I use Relay to run shortcuts to turn everything off when I walk out the door or to lock things up when I go to bed. One press to turn off all lights, another to lock all doors and close the garage. I also don't have Relay tied to any hard-wired lights. The buttons currently control our Christmas Tree (which is on a Lutron) and the lights in a connected room (also on a Lutron). It's also nice to be able to set the thermostat right there and to see Wink activity.
I have several robots (aside from the GE Links I've already mentioned) that turn on the lights after dark when I come home or turn on the lights in the morning when I wake up (via when the Master Bathroom light is turned on). I have a complicated robot that works based on an unused Pivot Power Genius outlet. IFTTT turns that outlet on/off based on sunrise/sunset.. and then in Wink when that outlet is turned on/off it turns the porch light on/off. I also use a robot to turn on a fan in our bedroom (via Pivot Power Genius) when the bedroom light is turned off after a certain time of day.
The Spotter has mostly gone unused. However, the recent changes in the app make me want to get a couple Gen 1 Spotters on the cheap. First, they clarified that Gen 1 Spotter detects vibration and not motion. Good call. Second, they added a 'Sensors' category. I can go into Sensors, tap on Temperature and see the Temp from Nest, Relay, and Spotter. That gives me a quick view of how my whole house is heating/cooling. It does the same for Humidity, which is cool. Nest should really open up their API to let Wink get that data from Nest Protects because that would be boss.
At this point I'm waiting for more sensors (door sensors, motion sensors, etc) so I can really start automating instead of controlling. They just sent me (as a beta tester) a set of Pella Insyctive sensors. Hopefully that should be activated on the beta side along with the Z-wave door sensors they sent a while back.
All in all, Wink keeps moving forward and I would start recommending it to people who like to tinker and want to test the waters of home automation. Their customer support is really great, too if you have problems. At least in my experience. So, there are my thoughts several months in.
