      Subject: Garage Door Open too Long

      Your garage door has been open since #{time_opened.strftime("%l:%M %P on %-m/%-d/%Y")}.

      If the timer is disabled and this is expected, you may ignore this message.  Otherwise, please check the timer on the door and any obstructions.

      Thank you,

      Subject: Garage Door Couldn't Close

      An attempt to close your garage at #{time_attempted_close.strftime("%l:%M %P on %-m/%-d/%Y")} failed to close it within #{DOOR_CLOSING_ALERT_DELAY_SECONDS} seconds.

      Check to see if the sensor on the door is misaligned.  If the sensor is in the proper position, check whether the door is obstructed.
