I stress about packages sitting on the doorstep, so I was really excited about Amazon Key where they deliver packages inside your garage with this Chamberlain garage door opener. I am so pleased with this convenience and no longer worry about packages. I have set this up in TWO houses in difference states, with different internet providers/equipment and totally different experiences. In the first house, it was very easy to set this up. I followed the instructions in the box to initially get started. It comes with two parts: a “hub” which is the brain of the thing that plugs in to an electrical outlet, and a sensor that sticks to the back of your garage door with provided Velcro sticky mounts. First you install the MyQ app on your phone, and the app provides you with step-by-step instructions. It’s really easy. It also asks if you want to “show me”(watch a short video for certain steps). You can skip the short videos if you want to, but I found them to be very helpful. The major steps are: (1) sync the hub to your phone (2) connect the hub to your wi-fi (3) stick the sensor onto the back of your garage door (4) test the connection between the garage door sensor and the hub and test that it opens the door. After everything tests out okay, they tell you how to mount the hub in a permanent place. It needs to be plugged into an outlet in your garage, within 50 feet of your wi-fi source (your router), and at least 6 feet off the floor. I mounted mine to the ceiling in the garage, plugged it into the same outlet where the garage door opener is plugged in. The whole setup was very easy. So far, Amazon has delivered 4 packages inside my garage—out of the rain and away from passers by. I do not usually have a need to open my garage door remotely, so I pretty much use this just for Amazon Key deliveries. But, have you ever left home and then wondered if you remembered to close the garage door? This gizmo will let you know if your door is open or shut. Relief. Some people complained that the MyQ app is not integrated with other apps like SmartThings. I don’t really care about that. This device cost $30, and it came with a coupon to get $30 off my first Amazon Key delivery (limit of one). I have two individual garage doors, and purchased a second sensor for the second door. The first garage door setup was basically free. How can you beat that?? I had such a good experience with house 1, that I decided to do the same set up in our vaation home, in a different state. TOTALLY OPPOSITE EXPERIENCE tried literally everything, but the Hub would not connect. I finally concluded that my brand of router/modem in the vacation home was not compatible. I spent many hours researching this on the internet and also on the phone with both MyQ and Chamberlain both. They were both very helpful, but NO LUCK it just would not work. The router we were using was TP Link AC1900 Archer 8, and the modem was Netgear CM600. One or the both of them just did not work with this MyQ devise. TWO YEARS later, we changed internet providers to Century Link--they provide their own router/modem so I am not longer using the TP Link/Netgear equipment. I decided to try the MyQ hub again and it was VERY EASY to connect with no issues with Century Link's Quantum Fiber equipment. We have two separate garage doors with two separate openers. I was able to connect both garage openers to the same hub, and order an extra sensor for the second garage door. I am VERY HAPPY to be able to use Amazon Key service in our vacation home now. I don't know why, but it currently costs the SAME regardless of whether you purchase a complete HUB WITH the sensor OR a second sensor alone. Even though I could use the original HUB for the second garage door, I ordered the complete hub/sensor set and am using only the sensor for the second garage door. I figure that I have a "free" backup HUB in case I have a problem with it later. I write honest reviews to help others make informed purchases. I do that because I read reviews myself and appreciate how helpful they can be. I hope my review helped you.
