I've had my Haven for about 45 days now. Its one of the first things I installed in my new home. I wanted to be able to keep an eye on the temperature from anywhere, and be able to turn the heat down during the day and anytime we're out of the house for a bit, but still be able to return to a warm home. As a thermostat, I have no issues with the Haven. It's intuitive, its kept the house quite comfortable, being able to cycle the fan is nice, and programming was a breeze. Installation was also quite simple. However, the wireless connection is a big issue. The nest looses connection several times a day.
I am not running a cookie cutter home network (untangle for a router, and ubiquity APs) but even on the ISP router that i had in place temporally i also was experiencing connectivity issues. I could have easily run Ethernet to the nest, or if they had a reasonably priced 802.15.4 to Ethernet bridge i would definitely consider purchasing it.
Overall though, again, i'm happy, and with the wireless caveat would recommend it to a friend.
When I first heard of this thing, I couldn't believe it. Who needs a $200 thermostat? Turns out I did - I'd constantly forget to turn the heat/AC off when I left the house, and since I work a 12 hour shift, that's a lot of money down the drain. I knew you could get programmable ones for much, much cheaper than this, but the smartphone app/website to control the NEST made this more appealing. Turn the A/C on remotely so the house will be comfy by the time I get home? Turn the heat on from bed using my phone? Receive a detailed breakdown of usage stats? All this just sealed the deal. When I saw this thing on sale I couldn't resist.
PROS: First, setup is a snap. I'm terrible when it comes to assembling/installing things, but this was quick and easy. Took me less than 10 minutes, it should take most people around 5. Connecting to wifi was painless, the app for Android is clean, functional, and reliable. The NEST looks great too - people are always oohing and aahing about it when they come over.
But most importantly, this thing saves me money, period. I spent $97 on electricity last May, and $49 this May after I installed the NEST. Sure, there could have been other factors like weather involved, but over the summer, I spent $69 in June whereas last June I spent $119. And $95 in July where I spent $159 last July. Bottom line is I'll make my money back in just a few months - you can't really argue with these numbers.
Love the innovation of the product. However, for last few weeks nest reports low battery every few hours and then disconnects from wireless network to conserve battery. Once offline, I cannot control it from iPhone and neither can it talk to its servers to leverage the "learning / programmable" feature. Talked to customer service day before Yesterday and had a very disappointing experience.
Customer agent said it is owing to Apple Extreme / Express router. He further claimed that Apple routers are not compatible and result in faster battery drain. I used nest with Apple router for ~5 months without issues and now am being told problem is router. He was not willing to entertain another logical explanation that the lion battery inside nest had simply lost capacity to hold enough charge, a common occurrence with rechargeable batteries.
This is really a perfect product. It looks nice, works in the background and just installs without any issues.
Brilliant!!
The Nest Thermostat is amazing! From setup/installation to using it on a daily basis, the team at Nest get user experience.
I have two of these and they work flawlessly. No more confusing thermostat scheduling or controls.
My favorite feature? Having control and visibility to my thermostat from anywhere that I have internet access!
Even though I hardwired the electrical to interconnect the smoke detectors per code, the design of these is so amazing that I couldn't resist!
