With summer just around the corner, now is the perfect time to invest in a smart thermostat. Unlike traditional thermostats, smart thermostats can be controlled remotely from your smartphone, allowing you to adjust the temperature of your home before you arrive.

With Memorial Day sales in full swing, ecobee is offering killer deals on some of our favorite smart devices. In fact, ecobee is offering $50 off one of the best smart thermostats we've ever tested. This deal won't last long, so get it while you can.

A feature we liked in our review of the ecobee SmartCamera is the camera's SmartFocus feature. When it detects a person, it digitally pans and zooms to center the person in the frame. Other features include person detection (the camera does not activate if a pet wanders around) and window mode (disables the camera's infrared light to eliminate reflections at night). It is also possible to create activity zones and adjust the camera's motion sensitivity.

Meanwhile, ecobee SmartThermostat reviewers gave the upgraded device a near-perfect 4.5-star rating, boasting full compatibility with Alexa (the previous version was missing some of Alexa's core features) and support for Spotify We also like this thermostat upgrade speaker, which now supports Spotify. To be fair, the ecobee is not a replacement for a daily-use speaker, but it is a welcome option if you want to listen to tunes while cooking or reading. Meanwhile, the new sensor is slightly smaller, has improved battery life (up to five years), and a longer operating range (up to 60 feet from the thermostat).
