"High End, High Quality thermostat!"4.5 starson by cawgijoe1
Pros: Easy to install. Well made. Remote access. Easy to use. Informative. Cool looking. Firmware upgradable for future features.
Cons: Price. I debated the cost, but am happy that I bought it.
Summary: Much higher quality product than any of the other thermostats I've seen at Home Depot, Lowes, etc. Comes well packaged with easy to understand instructions. Very easy to install and set up. The Nest replaced a nice Honeywell 8500 touchscreen thermostat that I had for years. I set the Nest up with my current schedule but did leave learning on. So far it's working as advertised. My thermostat is located in an upstairs hallway so I disabled the Auto Away feature as we spend alot of time in the family room and kitchen area. If you are anywhere near Nest in your home, the Auto Away feature looks like it would work well. I'm hoping that Nest comes out with separate remote sensors that can be placed in areas that are frequented and will communicate with the thermostat so that I can use this feature in the future. This is a reallty cool device. Will it save me money? Maybe. I already used the capabilities of my last thermostat to it's fullest, so maybe not. But thats ok, I'm a gadget freak and this thing is way cool. My two concerns: WiFi can be hit or miss, that's why I have most of my devices hard wired to the router in my house. hard wiring is more robust. There are times it may go out, but the thermostat will keep working based on your programmed schedule till you connect back up. The other concern that several have mentioned here is charging the battery. My understanding is that the battery is charged when the system runs. If it's idle for a long time and needs to get juice, it will cycle your system to draw power. Some systems are sensitive and this may be a problem.If you have this issue, there are a couple of ways around this...you can remove the thermostat and charge it using the USB connector on the back. Not the most convenient, but an option. The other is to use a C wire if you have one, or if not, you may have a spare in the bundle in the wall that can be hooked up to the furnace and the Nest. If none are available, adding a C wire can be done, but could be a real pain for DIY. You may have to pay an HVAC technician for this. So far, enjoying the nest!
