After my experience with multiple installations I wanted to list the most reliable solutions. These are listed from most reliable to least reliable. Hopefully this helps people before they make their large purchases.
- Lutron Caseta and RA2 select
- Zigbee 3.0
Lutron is the most reliable but it is very limited on what it can do so I do mix a lot of Zigbee devices (ie Motions) with Lutron devices with Hubitat handling everything.
Z-wave has a lot of issues if there is a failed device and I believe it has been responsible for loading up the Hubitat Hub. I do still use Z-wave for locks and Somfy blinds but I make sure it is a direct hop to the hub and keep only a few Z-wave devices on the network.
Wifi devices have just been the most unreliable when it comes to switches and motions but I do have some success with Thermostats and Rachio.
