The Ecobee4 WiFi Programmable Thermostat with a Room Sensor and Built-in Alexa Voice Service drops from $249 to $229 when you apply the code 7XY8LLW2 in your cart at Lowes.com. Plus, the shipping is free. This is the only discount we could find for one of these new smart thermostats anywhere. The included room sensor will collect data to create a heating and cooling profile for your home so the thermostat can autonomously adjust the temperature. You can also adjust profiles using the accompanying Android or iOS app or with voice commands since they have a built-in speaker and come with a full-featured version of Amazon's Alexa. Sales tax is charged in most states. Note: Be sure to check the rebate link on the product page to see if your local power provider is offering an additional rebate.
