As one of its daily deals, Home Depot offers the Emerson Sensi WiFi Programmable Digital Thermostat, model no. UP500W, bundled with the Emerson Wall Plate, model no. F61-2663, for $99.99 with free shipping. That's tied with our December mention and the lowest total price we could find by $29. (We listed the thermostat alone for $79, also in December.) The thermostat allows for WiFi control via Emerson's iOS or Android app and is compatible with Amazon's Alexa for voice control. Two AA batteries are required, included. Deal ends today.
