Editorial Reviews

Sometimes you just forget to close the garage door. But if "sometimes" is closer to "usually" for you, you may run the risk of having your garage emptied out by opportunistic passers-by, and you will certainly pay more to heat your house. Chamberlain's Clicker Garage Door Monitor helps you minimize the likelihood that you'll leave the biggest door in your house open. The device mounts easily without tools to your garage door via a Velcro strip; if your door is open, the sensor sends a signal to the monitor, causing a red light to flash. The monitor may be plugged in anywhere in your house where you're likely to notice the flashing light. Depending on your garage-door habits, this device could help prevent theft and lower your heating bills. Includes lithium battery.--Josh Dettweiler

Great tool to make sure the garage door is not left open.

This device shows a solid green LED when the garage door is closed and flashes a red LED when it is open. This item gives great peace of mind at night when someone else comes or goes from the garage.

Comparison of Chamberlain CLDM1 and Skylink GM-318

Reviewed by Alan Mayer, 2010-02-09


Quick summary: Both units work very well. The Skylink has a beep in addition to LED indicators. But, the beep starts as soon as the garage door is opened which is annoying. A 5 minute delay on the beep would be perfect for me. The chamberlain can monitor multiple sensors, but only has one LED indicator for all sensors. The Skylink has separate LED lights for up to four sensors of different types.

If you want the beep, or want to know which sensor is triggered, the Skylink may be better. Otherwise, both units work great.

I got the Chamberlain first and installed in 5 minutes. The transmitter attaches easily to door with provided double stick velcro. The receiver (with green/red LED indicators) has to be plugged in, which does limit the choices for mounting. In one month of usage I had to reset it once because it was showing the garage door open when it was closed. As another reviewer noted, simply unplugging the receiver and plugging it back in fixed the problem. If the door is closed a green LED shines, if open a red LED blinks. Odd that the red LED is dimmer than the green LED.

I thought it would be nice if it would also beep when the garage door is left open so I tried the Skylink GM-318. I got the Skylink today and it installed easily. I did have to fiddle with tiny dip switches on the transmitter and receiver, but it was pretty easy with the supplied tool. I think the receiver works from a bit farther away than the Chamberlain.

I was disappointed with the beep feature because it starts beeping as soon as the door is opened. I don't think my family will appreciate the beep when I leave for work early in the morning. If Skylink (or Chamberlain) reads this, it would be really nice if the beep could be configured to start beeping after the door has been open for 5 minutes. The beep volume can be set to off, low, or high with a switch. It also has a mute feature which you can press if you know the garage door will be open for a while. When the garage door is closed, it automatically turns off the mute and goes back to normal operation. The Skylink uses a different kind of sensor than the Chamberlain that is mounted at the bottom of the door with supplied two sided sticky tape and has a pencil shaped sensor that senses the floor of the garage pressing up on the pencil shaped sensor. The sensors for both units work well and appear to be well designed.

Overall both units work well. If the Skylink had a delay on the beep, I'd like it better, but I'll probably turn off the beep to keep from annoying my family and my dog. The Skylink can monitor up to 4 devices with a separate LED light for each, and a different beep pattern for each. Skylink has sensors that can monitor garage doors, motion sensors, water sensors, and other types of sensors.

Why have I waited so long . . . ?

Recently, I had two issues with my garage door opening and closing on its own--both issues within a span of about two weeks. I was beginning to think we had ghosts. The first was caused by a defective remote control (subsequently, I replaced the old remote with a new one and that solved that), the second was caused by a broken connection in one of the floor sensors on my Genie door opener (I re-soldered the broken solder joint on a circuit board and that fixed that). Anyway, while in the house, I never knew if the garage door was open or closed (the alarmed neighbors did). So, after reading other reviews on this Chamberlain monitor--good and bad--I went ahead and ordered it. The sending unit is separated from the receiving unit by at least 20 feet with two walls in between. My friends, the monitor works perfectly and flawlessly every time. The receiving unit, which has a red light for OPEN and a green light for CLOSED is positioned withing sight from the kitchen, family room and the living room. It is comforting to see that GREEN light and to be assured the door is closed. The installation was so easy even a caveman (oops) could do it. The receiving unit plugs into the wall using one of those low voltage adapters. The sending unit uses one of those nickel-sized batteries, so I will have to keep an eye on it. The price on the unit was excellent. I asked myself "why did I wait so long to get this unit." Now, if I only had a receiver in my car, I possibly could tell if I left the garage door open after I drove away. Oh well . . . !

Great Little Product

This monitor has worked just as promised. The set-up was very easy, and the green and red LED's are easy to interpret. Since I've had it, my girlfriend has not once left the garage door open.

Works as well as claimed

Works great. I have the receiver installed about 15 feet away from the sensor and it works flawlesly. It's not real heavy duty but it works as it should. It is wise though to keep the receiver as close to the sensor as possible so you have less chance of loosing the signal. You wont go wrong with this one.
