Wife and I are about to close on our first house, and it's an opportunity to do many things without the compromise that comes with smart home projects in a rental. I've spent hours reading threads about certain devices, and developed a plan for many "things" that will in some way tie in to Hubitat.
Even for someone with a few years of experience (and nearly one year with Hubitat), the research can be overwhelming. It would be great to hear the lessons learned by all of you and hopefully help myself and others avoid headaches. I am prioritizing reliability, usability (speed, and blending into the background), and keeping things reasonably local. WAF isn't an issue at this point
Security
HSM has served us fairly well using a mix of zigbee and zwave motion and contact sensors. But for various reasons, I'm quite interested in a standalone security system + Envisalink. Debating between the DSC and Honeywell systems, I'm pretty set on the idea of a DSC Powerseries 1864 with a mix of wired and wireless sensors and keypads. I would use the security system's sensors in Hubitat for automations.
Leak sensors
A few options for zwave/zigbee leak sensors, though the standalone security systems also have compatible leak sensors (wired and wireless). Any thoughts on the reliability of either? I'm leaning towards sensors that would work with standalone security. I do already have a Zwave WaterCop to install on the water main.
Smoke and CO detectors
Pretty much settled on Nest Protect. Three smoke detector locations in the house are hard wired, and Nest would allow us to add wireless versions in other areas.
Door locks
This is one of the more convoluted areas. I haven't found much agreement on preference of Zigbee or Zwave, or for brands/models of locks. I have the impression that people prefer Zigbee in this application. Because Schlage deadbolts are Grade 1 (something that really probably doesn't matter), I'm tentatively planning on going with Zigbee version of the Schlage Connect deadbolt.
Wall switches and dimmers
I'm reasonably certain that this 1964 built house does not have a neutral wire to wall switches. Given the many threads on Lutron, I'm leaning towards Lutron Caseta. However, new Zwave dimmers and switches are coming out that do not require neutral wires -- but it sounds like the reliability and immediacy of Lutron switches and hub is worth it over Zwave. I don't expect to come close to the device limit for Caseta.
Themostat
I debated a Zwave or Zigbee thermostat vs. learning, and think I'm leaning towards an Ecobee4 from Costco. I'm really not sure how much I plan to integrate the thermostat with Hubitat, but it sounds like Nest is no longer worth considering.
Window coverings
Getting a little off topic here, but after recovering from sticker shock on smart shades/blinds, we're leaning towards motorized Bali roller shades with Zwave. I'm not against a DIY solution, but haven't read much that leads me to believe it's worth doing over simply buying the shades.
Other things
I can't think of much else that I plan to do in the near-term. I'm leaning towards ditching my single Arlo Plus and installing Ubiquiti cameras with a Cloud Key Gen2, realizing there is currently no integration with Hubitat.
My own notable good or bad experiences:
-I've yet to find a zwave/zigbee siren that I'm happy with. I've tried many, both with Smartthings and Hubitat -- all have been buggy or unreliable at best.
-Keypad for HSM is great to have, even if you're arming/disarming in other ways.
-GE Link zigbee bulbs have all been unreliable and need to be repaired every few months.
-Hue hub + bulbs have been flawless, though I'm hoping to step away from smart bulbs.
