The ecobee Total Security and Savings Bundle is a strong choice for anyone looking to upgrade their home with a smart thermostat and security system that works well with Apple HomeKit and other popular smart platforms like Alexa and Samsung SmartThings. The smart thermostat offers a clear, easy-to-use touchscreen interface and connects via Wi-Fi with wired power, ensuring reliable operation.

The doorbell camera’s wide field of view and clear HD video make it easy to monitor visitors day or night, with handy two-way talk from your phone. Remote access and detailed notifications keep you connected wherever you are. Additionally, the bundle supports extra security features like automatic system arming/disarming to prevent false alarms and offers professional monitoring options with video storage for added peace of mind. While the design is sleek and modern, the need for professional installation and a wired setup might not suit everyone, especially those wanting a simple plug-and-play device. Also, some advanced security features require a subscription plan.
