I was/am in your exact same boat.
- I purchased the Lutron Pro for Caseta integration. I'm SUPER happy even though it wasn't cheap.
- Dome Water valve works great. I even bought more and a few SmartThings water leak sensors as well
- For Ring, I use this absolutely excellent Ring App [WITHDRAWN] Unofficial Ring Integration
- For the Wink2 - once I migrated over, I removed all my devices and moved them to HE, I then turned my Wink2 into a z-wave repeater which has been fantastic. Instructions here: Wink Hub 2 as zwave repeater/secondary controller
Glad to have you. While Wink was awesome and I miss some of their stuff, I'm 1,000 times happier on HE and I'm actually starting to 'automate' my home instead of just having a good smart way to do timers and remote control.
