I'm a tech junkie who allowed other companies to setup and do the controlling of my smart home for way too long, and want to use the Hubitat to integrate what makes sense to keep, and replace what doesn't with the most ideal devices on the market.
Current Smart Devices: Ring Doorbell Pro, Schlage Connect Z-Wave Lock, MyQ Garage Door Hub, 2 Z-Wave G Control GC-TBZ48 Thermostats, Nest Cam (wired older model), CCTV System with DVR (hardwired) and accessible via SuperLivePlus mobile app, Evolve LPM-15/TV-15W Z Wave Plug
Current Support Hardware: Aerotec DSD37-ZWUS Z-Wave Repeater x2
Context: All of the above was previously on a monthly paid monitoring setup and integrated using alarm.com, but I got tired of paying for something I could do much myself with their lack of actual support when I needed it and always trying to force sell me more equipment.
My home is a 1.5 story just under 2600 sq ft in total
The Ring Doorbell, and Schlage are at the front door, with the attached garage/MyQ to the left when at my front door. The first thermostat is nestled in a small hallway that leads to my garage from inside, the other is upstairs in my 1/2 story along with my router/modem, CCTV/DVR, and my office.
My big concern is that my 1/2 story is only accessible via a straight staircase (15 steps in length) and is toward the back of the house, and expands to border our walk-in attic over the garage going back toward the front of the house. Since it's not open like a loft I have concerns about the Z-Wave penetration and how successful a network even with repeaters might be. My staircase doesn't have any plugs along it for repeaters so best I could do is at the top of the stairs along my wall and perhaps somewhere downstairs and so on.
What I am really seeking in my post: Can a Z-Wave network be successful with my current setup/layout? I can move the router/modem if need be, but my wife requires it be out of sight so that limits the locations I can place it, and also requires reconfig of my CCTV using a repeater, and consideration of my office wireless connection quality dropping. Are there any devices that straight up should be replaced/upgraded to something more ideal for the DIYer? Price isn't a real issue for me as long as I can justify the investment and also because I can purchase it in parts if it gets really expensive.
If the info in my house layout isn't specific enough or you need anymore information please let me know. Thanks for your help and I am excited for the things to come.
