No C-wire needed, works well, & looks nice

Three reasons I like this product:1) C-Wire: I don't have a c-wire available. There are VERY few modern smart thermostats that claim to work without one.I first tried one of the others, the Sensi. It did not have any apparent easy way to determine in advance if it would work without a c-wire. It didn't work for me. The lack of an easy advance tool cost both of us time and money; a lose/lose. A wrote a well-deserved 1 star review of that product.This product does have a very easy tool to determine in advance if it will work without a c-wire. It took me literally 10 seconds to use that tool & be confident this would work. And, it does, in fact, work great without a c-wire.2) Functionality:It comes with a remote temp sensor which is a new thing for me and a great idea. I put mine in the bedroom. It was crazy-easy to set up and I really like the simple interface letting you choose when & how you want the thermostat to use it. It says you can add more of these if you want.Programming a daily schedule is incredibly easy as is making quick adjustments to that schedule.It has all sorts of other features such as auto-adjusting based on who is home, learning your patterns & making further auto adjustments, accepting voice commands, and so on. I do not want to use any of those things. They made it very easy for me to just say "no thanks" to all of those things and still have a nice seamless experience.3) Appearance: I hesitated to buy this product because it is round while my previous thermostat was rectangular and the wall is messed up everywhere behind the area of the old thermostat. Yes, I can patch a wall and paint it - but, no, I don't really want to if I can avoid it. It was a pleasant surprise to me that this thermostat came with an optional large faceplate that is made to cover up the bad wall in exactly my situation. I used it and it is great.Privacy is a concern but that seems to come with just about everything these days so - I don't know - just get over it?I recommend this.Ver más

So convenient and beautiful display.

Debated between polished silver and black obsidian. Went with silver because lower price. Happy the way of looks. Upgrading from Gen 3 Nest and this has a much larger animated display. Uses google home instead of the Nest App. Working great, quick instantaneous turn on and off once you switch temperatures setting. No lag. Really like the animated display. Installation was straight forward. I had a common wire but the unit is supposed to to work even without a common. Installation took less than 15minutes. My phone saw the new device and asked to connect to WiFi. Once connected new firmware was downloaded. No problems and so convenient to be able to remotely control thermostat. Not sure how effective the remote temperature sensor is. The systems takes the average temp of the thermostat and remote sensor (if selected) as your average room temperature. You can turn the remote unit off from app if needed.Ver más

So easy and convenient!

I don’t know why someone wouldn’t want a smart thermostat!This is our second one, first one we left behind at the old house. These are easy to install, even for someone not overly handy.The display is clear and bright. Works great from the app. This is amazing to be able to cool or heat my house before I get home from the app.It has definitely saved me money on utilities because I have mine set to go into away mode when my phone leaves the house.Great value for the money.Ver más

May not work in HVAC systems without a C wire, when the 3rd Gen Nest Thermostat will

When one of our 3rd Gen Nest Thermostats stopped working, I decided to replace it with a 4th Generation Nest unit. Oddly, the mounting hardware for the 4th Generation is completely different from the 3rd Generation, which is annoying. The wiring backplate is incompatible, as the 4th Generation has a different electrical connector to the thermostat. One nice thing about the new backplate is that there is a light built into the bubble level which signals voltage on the Rh or Rc wires from the HVAC unit, implying you won't need a dedicated C wire for power. Unfortunately, this is many times not the case for the 4th Generation, lit bubble level or not.When I properly mounted and connected the 4th Generation thermostat, the setup app on my phone reported that there was "no power" on the R wire, even though the bubble level was lit, and I could measure the voltage on a multimeter. There was no way to get around the error message in the app. A call to Google support was completely useless. The support person clearly didn't know why the setup app falsely reported "no power", or whether or not the 4th Generation thermostat required higher voltage on the R wires than the 3rd Generation thermostat for operation without a C wire.An internet search revealed numerous people posting on Reddit and other web sites of the same issue I was having. How could Google support not be aware of this? Depending on your view, the difference between the R wire voltage requirements for the 4th Generation from the 3rd Generation thermostats is either an undocumented design change, or a design flaw. Personally, I consider it a significant design flaw, especially that it is not documented in the setup instructions, and there is no warning of this anywhere in Google's documentation.After spending about two hours removing the 3rd Generation mount, installing the 4th Generation mount, waiting for the callback from Google, and figuring out the root cause myself, I unmounted the 4th Generation Nest, packaged it back up, and returned it. I ordered a new 3rd Generation Nest from Amazon, and it works flawlessly with the HVAC unit.One attraction of the 4th Generation Nest is that the "maintenance band", the temperature variance range at which the AC compressor cycles on and off, is manually programmable, while on the 3rd Generation Nest it is not. There have been complaints that the 3rd Generation Nest's maintenance band is only two degrees F wide, which in some climates and homes cycles the compressor too often, and is blamed for excess wear and premature failure on the compressor. (AC units and heat pumps both use compressors.) So if you have a C wire in your compressor-based system, I recommend trying to use a 4th Generation Nest. Another trick which works with both generations is to use a remote sensor in a different part of the room or another room where the ambient temperature doesn't vary as quickly, to reduce compressor cycling. I use this trick for our 3rd Generation Units, and it also works for 4th Generation thermostats. Note that using a remote sensor this way may require some experimentation to get the desired result, while the feature to manually adjust the maintenance band makes it quicker and simpler.I really like the Google Nest thermostats when they're working the way they're supposed to, but the lack of backward functional capability from the 3rd Generation model to 4th Generation model is inexcusable, since there's no warning about it. And Google support is ineffective in helping less technical buyers. The least Google could do is document the issue properly on their web site.

Game Changer for Home Climate Control

Upgrading to this thermostat has completely changed how I think about home temperature control. It's not just a programmable thermostat – it's actually smart in ways that make a real difference in comfort and energy savings.The learning capability is impressive. After the first week or so, it started anticipating when I wanted the temperature adjusted without me having to do anything. It picks up on your patterns and creates a schedule automatically based on how you actually use your home. That means you don't have to spend time programming complicated schedules or remembering to adjust things manually. It just figures out what you want and does it.The display is gorgeous. It's got this clean, modern look that actually adds to your home's aesthetic rather than being an eyesore like traditional thermostats. The screen is bright and easy to read from across the room, and the interface is incredibly intuitive. When you walk up to it, it lights up and shows you the current temperature. The whole interaction feels polished and well thought out.What sets this apart from other smart thermostats is how well it works with the temperature sensor that's included. You can put the sensor in the room where you spend the most time, and the thermostat will prioritize that room's temperature when making decisions. This is huge if your home has uneven heating or cooling. Instead of managing the temperature based on where the thermostat is mounted, it can focus on keeping comfortable the spaces where you actually are.The energy savings are noticeable. The system is smart about when to heat or cool, and it's not wasting energy when you're not home. It can detect when you've left and automatically adjust to save energy, then bring things back to your preferred temperature before you return. Over time, those savings add up, and you can actually see the impact in your energy bills.Remote control through the app is seamless. Whether you're at work, traveling, or just in another room, you can check and adjust your home's temperature from your phone. The app is well-designed and responsive. It gives you detailed information about your energy usage and even provides reports on how efficiently your system is running. That level of insight is something you just don't get with a traditional thermostat.Installation was straightforward. The instructions are clear, and if you're comfortable with basic DIY projects, you can handle it. There's also a compatibility checker on their website to make sure it'll work with your HVAC system before you buy. Once it's installed and connected to WiFi, the setup wizard walks you through everything step by step.Voice control works perfectly with both Alexa and Google Assistant. Being able to adjust the temperature with voice commands is one of those conveniences that seems small but becomes something you use all the time. "Hey Google, set the temperature to 72" is so much easier than walking over to adjust it manually.The Nest Aware features give you additional insights into your home's environment. You get alerts if there are unusual temperature changes, which can help you catch problems with your HVAC system early. The system also provides tips on how to optimize your settings for better efficiency.Build quality is excellent. This feels like a premium product from the moment you take it out of the box. The materials are high quality, the engineering is solid, and everything about it feels durable and well-made. It's clear this was designed to last and to look good doing it.The fourth generation improvements are noticeable if you've used previous versions. The display is better, the sensor integration is more sophisticated, and the overall performance is smoother. Even if you haven't used an older model, you're getting the benefit of years of refinement and improvements.For anyone serious about smart home technology or just wanting better control over their heating and cooling, this is an investment that pays off. The combination of learning capabilities, energy savings, remote access, and the included temperature sensor makes this a complete solution. It's made managing home temperature effortless while actually reducing energy costs. Really impressed with how well this performs.
