Where is the pinhole Reset button?

On the specific models of digital and smart thermostats that do feature a physical hardware reset mechanism, the pinhole reset button is typically located on the side of the thermostat housing, underneath the removable faceplate on the circuit board, or inside the battery compartment. Because these buttons are intentionally recessed behind tiny pinholes to prevent accidental resets by children or routine bumps, you cannot press them with a finger. Instead, you must insert a slender, rigid tool—such as a straightened paperclip, a SIM card removal tool, or the tip of a fine mechanical pencil—firmly into the pinhole until you feel a soft click, and hold it depressed for several seconds. This action forces the device's internal microprocessor to reboot and clear corrupted memory. You can verify that the pinhole reset worked when the display screen goes blank and restarts.
