How this automation works

Keep your home warm automatically when the temperature drops below your set point. This Applet runs when Weather Underground reports a lower temperature and adjusts your Honeywell thermostat to heat mode, then sends alerts and logs the event. Perfect for maintaining comfort, saving energy, and staying informed of changing conditions across all your devices. Note: Install the IFTTT app on the device(s) where you want to receive notifications.
