I revisited the Echo setup and enabled the "Almond for Smart Home" (previously used the "Almond" skill) and tried setting temps again. **In Heat or Cool mode** the temperatures set perfectly ("Alexa, set the thermostat to 62"). However, when the thermostat is in Auto mode, it it responds with something like "aiming for 62" or "setting thermostat to 62" and misses the target by 2 or 3 degrees, setting 65 or 66. I've tried using keywords like "high temperature" as used in the Almond app, but can't get it to set a specific temp while in Auto mode.
No worries, though! The WAF just went way, way up with correct temperature setting via voice!
