If your home has multiple garage doors, it can be difficult to keep track of whether they're open or closed. The Chamberlain garage door monitor add-on sensor attaches to a garage door and sends information back to your Chamberlain garage door monitor. Simply by looking at your monitor, you'll be able to tell if you need to run out and close your garage door before retiring for the evening. Because this sensor uses a coin cell battery, you can easily replace the battery as needed.
