I have recently been offered a large discount on Lutron equipment (engineering, I spec out a lot of Lutron equipment for commercial customers). I've always had a tough time with keeping a good mesh with various devices misbehaving, or outright not working. Specifically my HEM, but honestly kindof everything that has to do with ZWave.
My understanding: If I replace all of my switches (currently Zooz and Innovelli) with Lutron, this means the entire Lutron network is separate in the same vein as my Hue stuff (which are supre reliable). So, I will then have a "hue mesh", a "Lutron mesh", a Zwave signal, and a zigbee signal coming from the Hubitat proper. Once switches are out of my system, I will have no repeaters.
Now, my home is wood contruction, plaster walls, and is a 1,200 sq.ft ranch that is kindof L shaped, but it's basically 32ft x 40ft. I have my Hubitat hub centered to the house in the floor joists of the main floor, and directly above it at the ceiling of the main floor is a Unifi AP non-LR that covers my entire yard from this position (120ft x 55ft).
Am I honestly overthinking all of this repeater stuff? My house is not large, should I expect reliable connections straight to my Hubitat in this general configuration (no device in my house will ever be more than about 40' from the hub)? Almost all of my devices are Zigbee motion sensors, door sensors, or leak sensors. My only ZWave devices (that I remember) are my super unreliable HEM, and my deadbolts. I really like the idea of no repeaters so I can have the Hubitat on battery backup and it can still respond to all sensor inputs intelligently.
I know I can try this myself, but it will involve a lot of removing devices and breaking automations to test. Looking for a bit of a sanity check where this has a reasonable chance of actually working, I don't think I've ever tried to use anything without repeaters. My first equipment were peanut plugs and SmartThings, it basically needed those repeaters to work.
