I see it has the option of C-wire power or 4xAA batteries. I wonder what the battery life is if using Zwave?
(reviews suggest "a few months", but not clear the amount of use)

Still very good, about a year
You can always just install transformer locally, just connect 12-24V AC power to the C and R screws on the thermostat

Yup. I think it is pretty rare for a furnace to not have the C wire terminal just maybe your installer didn't pull it. On mine the wire to the thermostat had an extra wire that wasn't terminated on ether side. Simple wiring on both sides. I use this thermostat and it is great. When the C wire is hooked up I think it will also work as a repeater for your z-wave network.

Good point, yes it works as repeater when connected to AC power source.

I have a wifi Honeywell from a few years ago that is working fine, but doesn't really integrate well with my Wink 2 hub so I still use the separate Honeywell app. Any benefits of this with zwave over my Honeywell?

No, it goes by the age of the house. It's rare for a thermostat not to have a C wire now, but 30 years ago they used simple thermostats without a C-wire. The difficulty of pulling one from the furnace location (or other AC power source nearby for a transformer) depends on the construction of your house.

I have an older place where thermostat is connected to fireplace - no C wire.

Bought a Zigbee thermostat that uses 4 AA batteries. Battery lasted about 15 months. Different technology and product but hope that provides a general idea of how long they last.

Well, this will be way more flexible, but if the Honeywell works for you ...
This is great using ST, not sure how far is the development on Wink

Not rare at all. MOST installers won't pull the C wire. Why? Simple: for heat and AC you need 4 wires. The 'C' is a 5th wire which isn't required.

MOST installers use 4 conductor cable for the thermostat. It's by far the cheapest cable you can get (cheaper then the 5 conductor "thermostat" cable), so almost all installers run it.

Note I'm talking about both older (60 years old & 30 years old) and brand new houses (< 1 year old).

If you have a 'C' wire great, but don't count on it.

I said that most furnaces have a c terminal so if you have a spare wire you could wire it up. If you don't have AC then you could have spare wires. I'm pretty sure that that was the reason I had an extra conductor.
