Regarding savings - Alexa Hunches is a very convenient function, which consists of savings. Alexa Hunches is a feature that allows Amazon's voice assistant, Alexa, to offer suggestions based on your daily habits and the connected smart devices in your home. If Alexa detects an unusual pattern or if something is missing, such as a connected door being left unlocked at night, it will proactively suggest actions to help you maintain your routine and enhance home security. This thermostat is compatible with most 24V HVAC systems, including air supply, heat pump, and radiant boiler, but not 110-240V systems like electric baseboard heating. A C-wire power cable or adapter kit is needed for operation. Check compatibility before buying.

I saw the mostly positive feedback, but some folks faced issues with installation. After that, the thermostat didn't quite nail its heating functions. There were also problems with a cluttered application and emergency heating settings (it is ignored). However greater number of users did not notice any problems, so there are no mass problems, and the Amazon Smart Thermostat deserves its place in the top smart thermostats of 2024.

Google Nest Thermostat is a high-performing and user-friendly device compatible with 85% of existing HVAC systems. It's straightforward to install and comes with detailed video instructions provided by Google. However, before undertaking a full install, ensure you have all the necessary tools and materials ready. It's worth noting that this thermostat requires two AAA batteries (included), which Google assures should last about two years due to its power consumption from your HVAC system.

The Google Nest Thermostat is fully controlled through the Google Home app. It allows for traditional programmable thermostat functions such as temperature and time interval selection, as well as modes for heating, cooling, and energy-saving. The thermostat also supports Google Assistant and Amazon Alexa, enabling you to change the temperature via voice control, and providing regular updates such as when to change your HVAC filter for optimal system performance. The Nest Thermostat is elegant in design and comes in four different colors to match your interior. Again regarding the feedback, the majority is positive, as a sales leader should be, but some had problems with support and installation. Although it doesn't support additional sensors, it offers a great balance of design, performance, and value, especially for those already in the Google ecosystem.

The Nest thermostat is compatible with a wide array of home devices through Wi-Fi, such as remote controls, lamps, clocks, activity trackers, and smart speakers. For instance, the Nest Cam can automatically alert you if movement is detected in the house while the thermostat is in Away mode. Moreover, Nest can be integrated with the IFTTT (If This Then That), a versatile software platform empowering users to create conditional statements for automating actions across various apps, devices, and services. This integration streamlines the process of harmonizing different technologies seamlessly, boosting productivity and personalization through no-code automation that enables adjustment of thermostat settings based on secondary triggers. Of course, Nest is compatible with Amazon's Echo, through voice commands (e.g., "Alexa, set the thermostat to 75 degrees").

We read dozens of feedback and customers say while installation may require some effort, Nest's comprehensive instructions and responsive customer support ensure a smooth setup process. The thermostat's design is both aesthetically pleasing and functional - their words, featuring a large display and an interface that supports interaction with multiple smart devices simultaneously. However, it's worth noting its inability to monitor temperatures in multiple rooms concurrently and its lack of support for Apple's HomeKit, which may limit its appeal to users deeply invested in the Apple ecosystem. With its "no programming" feature, it is essential to acknowledge that the investment is worthwhile. As evidenced, reduced human intervention leads to increased savings

Furthermore, it employs radar technology to enhance the temperature readings and spot the presence of people in the home, even from afar or around corners. An embedded air quality monitor alerts you about poor air quality guides you to improve it, and sends reminders when your furnace's air filter needs changing. Serving as a comprehensive home monitoring hub, the ecobee Smart Thermostat Premium includes an in-built smoke alarm detection and sends alerts for potential break-ins when your system is enabled. Get notified during sudden temperature drops that could potentially cause harm. 

After checking reviews in online stores, let's summarize the positive points, namely that ecobee Premium Smart Thermostat boasts a beautiful industrial design. It's broadly compatible with various smart home ecosystems. A key feature that stands out is its outstanding user interface available both on the device and within a well-designed application. This device uses a radar-based motion detection system and provides support for remote temperature and motion sensors. Plus, it's extremely easy to install and configure.  A minor drawback is that Siri support requires an Apple HomePod or HomePod mini. Another disadvantage is that the air quality sensor doesn't trigger your HVAC system's fan to circulate the air. So why it's the best? ecobee Premium Smart Thermostat is a leader in its class, encapsulating everything a modern smart home device needs. Compatibility with almost all HVAC systems, the ability to use almost any voice assistant, and (I almost forgot) Spotify integration, many built-in security sensors, and of course remote control from the application. Well, simply, it has a rather modern look. And, of course, about savings - the manufacturer claims 26% annual economic efficiency, thanks to various settings and schedules. And it is worth holding back and checking if it works with the application's monthly reports. I would also like to mention the younger brother of Premium Thermostat - ecobee3 Light. This is a stripped-down premium version, but it can satisfy most of the needs of the general public even with fewer features than the premium and enhanced version.
