Wi-Fi (Cloud) vs Z-Wave Thermostat

I have a TRANE XR524 and it works well on Zwave. I have had to re-synch the device once with the HS3 Zwave controller to get the thermostat to display the right time (stupid DST). This has only happened once in the last 1.5 years. The thing I like about it is that I set temp defaults in the device. These take over in the event that HS3 goes down. Then I set my events to proc after the built in settings.

I just setup a Honeywell 9K wifi at my sister's new house and found the setup straight forward. The only thing I can think you would need to automate would be integrating custom events based on active detection of home/away.

The Honeywell even has a skill of their own. So integrating voice commands can be done without HS3. Do note that they are cloud supported. So there is some risk to brute force attacks. You end up needing the plugin for HS3. You need Internet for connectivity between:
1. HS3 and the thermostat.
2. The thermostat and the Honeywell cloud service.
is reliant on your internet connection.
