Google Nest Learning Thermostat - 3rd Generation - Smart Thermostat - Pro Version - Works With Alexa

Can’t go wrong with this thermostat. The only model we like to use. I am sure the newest is good as well, but at a much higher cost. This works very well, I can connect to it from my phone and change on the fly, and we have enjoyed them in multiple homes for a decent price.

This unit was to replace one that was over 10 years old; with the internal battery having died. It was shipped FAST and new, not resold, Smart Thermostat. Worked perfectly out of the box with easy programming to link with my phone and computer apps. I absolutely LOVE the nest thermostat; making it SO easy to control the climate in the house.

Very good price. Delivery as was described, right on time.

outside the fact google dared to use motherboard components that cant survive even a year of use, theres some pretty large flaws with the app.you cant sync ur nest to your phone in the case of a problem, you cannot connect the nest to your pc via usb to troubleshoot anything on the device even tho it has a usb port . the app cannot tell when wifi has died. it enters an endless loop of hunting for a signal or blaming ur house when the device fails its jobthere no firmware updates online, so if anything bad happens during an installation or upgrade ur basically sol, this imo is unbelievableoutside all of this, the app cant easily tell if ur home via ur phone, it maybe senses only once or twice a day max meaning it always runs the ac for hours until finally entering evo mode. its a simple api call but maybe google felt like they wanted to save money so they limited the interaction. they should have come up with a better solution. its a power waster.take away: go find a smart thermostat that aint a google product. the name of the game is useful functionality, easy programming, easy repair, and easy diagnostic. google was sloppy on everything involved and now im facing rmas because i decided to trust them

Bought and returned the 4th gen. The 4G is not an improvement, it is a lower cost de-featured version. Need a faceplate, extra with the 4G. Have a two wire boiler heat only system, you need a separate power connector device for the 4G to work. Make changes via the thermostat (not the app on your phone), the 4G UI is not as easy to use as the 3G. 4G requires the Google Home app, 3G works with the Nest app. Nest app is much easier to use (more intuitive).

super easy to install even for people like myself who are novices at DIY.sleek and super effective. my second nest

I have 2 at my cabin and just bought 2 more for my new home. My last home had a supposedly fancy version with the HVAC system and my HVAC installer said it would work better than the nest. I fell for it and spent 3 times the price on the matching thermostat. It was so much more difficult to use all the features and I wished for years I'd have stuck with a Nest. At my office, the local utility company was offering free Ecobee thermostats as part of their energy save program. I did that since it was free. Ecobee is also more difficult to use than Nest and if it wasn't free I'd have gone Nest too. When I moved here there was no question I'd go Nest again for both zones. There's no conflict with the Nests in 4 zones at multiple properties in one app. I will keep using Nest from now on. They simply work; my family understands how to use them without needing lessons; and hey, they look nice.

Installed two of thee in my RV and they are working great. The wiring for the original Thermostats was 12vdc, which is what is sent to signal the AC. I had to provide 24vac to the Nest since that is what it requires. This was done with $13 24vac transformer. I then had to turn that back into 12vdc. I did this with a set of 4 relays. The end result works great and its a huge upgrade from the original slide type thermostat, which was not accurate on temperature at all and had my AC running much longer than necessary.My only complaint so far about this device is the restrictions on the Farsight feature. The display can obviously show multiple lines, you can tell that with the weather option, which shows a large number for current outside temp and then three smaller temps below that for later in the day. They could easily show the inside and target temp as well as fan speed all on one screen.Be warned that in most cases you cannot just swap out your existing RV Thermostat with the Nest. Check what voltage and whether its AC or DC at your current thermostat first. If its not 24vac then you will need other components.
