The Google Nest Learning Thermostat (4th Gen, 2024) is a smart, energy-saving device that can bring both convenience and efficiency to your home. One of its top strengths is compatibility; it works with most 24V systems common in households, including gas, electric, and heat pump systems, and generally doesn't require complex wiring. This makes it accessible for many users. Installation is relatively straightforward, typically taking around 40 minutes, which is a plus for those who prefer DIY projects. The included Nest Temperature Sensor helps manage hot and cold spots, ensuring that every room can be comfortable, and it integrates well with the Google Home app for easy control and monitoring.

Its smart features are impressive; the device can learn your preferred temperatures and schedules, suggesting energy-saving adjustments you can approve through the app. It also works with Amazon Alexa, allowing for voice control, adding a layer of convenience.

The user interface is sleek and modern, featuring a polished obsidian finish and a large, easy-to-read display that adjusts brightness automatically or can be manually controlled.

However, there are a few drawbacks. The initial cost might be high for some, and while installation is generally easy, those with less common heating and cooling systems might find it more challenging.
