    • What Chamberlain doesn’t tell you (and should!)
Style: Old Version myQ Smart Garage Hub
You’re looking for a solution to open your garage door from a remote location. Package deliveries, the housekeeper, your tool-hoarding neighbor. This is one of several products out there that will do the trick. If you’re a garage door tech, move along. You know this already. If your a DIY homeowner with grand plans, you must read on - This is what Chamberlain should tell you about their system but doesn’t. While generally easy to install, without an Introduction or Basic Principles of Operation as a preamble, you will likely have the same issues I did. Read on for the lessons I learned and tips that will save your hair. I will explain each of the major elements of the system and provide suggestions to improve your probability of a successful installation. The Door sensor: This sensor communicates with the smart hub using Bluetooth to indicate door operation and open/ closed condition. During installation it is paired to the smart hub which is best performed with the unit attached to a closed door between 3’ and 10’ from the smart hub. By design, Bluetooth distance is limited to 33’ but don’t count on consistent operation at this extreme end of the range. Consider this distance during installation and future operation. Your 2.4ghz cordless phones, baby monitors, etc., can cause Bluetooth interference. Get them out. If your wireless router has a setting for Bluetooth coexistence, enable it. Your Wireless (Wi-Fi) Network: The Chamberlain documentation says that 2 bars of 2.4ghz WiFi signal is enough for consistent operation. This can be checked by looking on your phone. I say, your mileage may vary. I installed a dedicated access point for the smart hub as I couldn’t get the system to work reliably. A wired connection is also supported. Configure the smart hub with a static IP Address on your wireless network. This will help ensure the Chamberlain service can reach the smart hub quickly and easily when you activate the door. The additional time for the router or server to lookup a dynamic IP Address and establish a connection could create timing issues. The Smart Hub: The smart hub includes a Bluetooth receiver for the door sensor, a 2.4 ghz radio to connect to your wireless home network for the system to communicate with Chamberlain’s servers on the internet, and a radio frequency (RF) transmitter to send HomeLink rolling codes to your garage door opener (on a channel in the 300-400mhz range depending on your garage door opener) - just like your remote clicker. I discovered that the RF transmitter in the smart hub is fairly weak. While your car can transmit a signal a half block away, the smart hub can't. The instructions make a recommendation for placement of the smart hub but will make an explicit statement here - install it within the 4-6’ “recommendation”. Consider this when planning your installation. Apparently, orientation is important for maximum reach. If it doesn’t work reliably, flip it 180 degrees on its mount. Finally, like other garage door remotes, if it loses power you might have to re-program the system with the garage door learn button. They don’t tell you this so I will. Finally, the smart hub needs to be located where it can communicate with; 1) the door sensor (Bluetooth), 2) the garage door opener (RF) and, 3) your wireless (WiFi) network to work consistently! Each has its own distance limitations so placement of the hub is critical. Your garage door opener: You obviously have one to which you are adding this system. Do your homework and make sure it’s compatible before you buy. If you’re not positive, call or email them with your make and model numbers in hand. Mine is a Craftsman (Chamberlain) made in 1999 with the door sensors so I was good to go. NOTE: Garage door openers have a limit to the number of remotes they can support. My Craftsman supports 4 remotes. With two HomeLink-connected cars, the remote door opener, and the smart hub I am now at the max allowed by my opener. As a result, I had to decommission my "clickers". Do your homework and factor this into your plans. The Phone App: A basic, functional, app with a few frills. It works well enough though some settings are best changed on the web site (that I didn’t know about). When installing the smart hub your phone will need to be on your 2.4ghz wireless network to complete the setup. After that, it doesn’t matter what your phone is connected to - your home network or a cell connection. The system can be setup entirely from your phone. I set up an open alert, a close alert and a 10pm door not closed reminder. The alerts can be sent to you via Text or email. The Chamberlain service: Does not support Alexa or IFTTT (without a fee) and that’s fine for me. I always have my phone handy and I don’t need the security concerns that come with IFTTT. Also, multi-user accounts are not (yet) supported. I just program the wife’s phone with the same username/ password and off we go. The system is fairly rudimentary and in my opinion could use some added intelligence. If the system components exchanged more status information it could probably avoid situations where the “door [is] not responding” or better error status information could be presented to the user. Sometimes I think it’s just that Chamberlain's servers are slow. LED & Florescent lights: I hear you asking “why is this important?”. Both can emit radio and electromagnetic interference that can mask the signal between the smart hub and your opener. If you experience unreliable operation - out they go. The last thing I did was remove an LED lamp from a motion sensor fixture nearby and replaced it with a standard incandescent. Since the light is only on for a few minutes I’m not worried about the power usage if it means the garage door will close when commanded. I give Chamberlain credit for trying to make the install easy. Considering the different operating environments and variables, it’s a challenge to cover all the bases. Unfortunately, a quick start guide simply isn’t enough in this case and the online instructions are no better. They have made some assumptions about what you need to know (or don't need to know). The above precautions should be spelled out to avoid customer frustration and reduce the number of calls to their help desk (and returned product). The good news for me is that after 2 months of trial and error and multiple calls and emails to their help desk, I think we may finally have all the issues cleared up. My fingers are crossed. Now you know everything Chamberlain should tell you but doesn't. Best of luck! ... show more

    • Super Simple and solves so many little annoyances in life
Style: Old Version myQ Smart Garage Hub
Review Image by Irwin Electronics

So many mixed reviews. Are people not following directions? Likely. Do people have a weak signal in their garage? Good possibility. Should some people not be allowed around technology? Definitely! I was hesitant after the mixed reviews. But there's something to be said for over ten thousand positive reviews and number one bestseller. I also like the idea of a wired button and magnetic contact switch that others have over the "this is just another remote" approach the MyQ uses. However, there's also something to be said for a simpler install, portability, fewer wires, and cleaner looking. Just as others have said, follow the instructions. That's the best advice I can give you. If reading comprehension is not your strength, why are you reading reviews? Hire a handyman. The whole setup, and installation, was very quick and easy. If you can hang a picture, you can do this! I did not attempt to integrate with Amazon Alexa, Google, or ITTT. My new car does not have a Home Link mirror, so no remote. I didn't want an ugly clicker on my visor, and just something to leave behind in a rental car/truck. I've always got my phone, and if I didn't I couldn't close the garage until I ran in and grabbed it! Not to mention how many times did I already arm the alarm, but not yet check the garage door? A lot! how many times was the door left open all night? Even once is too many. How many times did I drive away and wonder, did I leave the door open? I see no mention of monthly fees for my install, and I did set up alarms in case the door was left open or did not close properly. I love the idea of turning my garage into my own Amazon Locker! How many times have I worried about packages on the porch? The whole install consists of two pieces of velcro and two drywall anchors with screws. The setup of the whole system was installing an App and pressing two buttons. If that frightens you, hire a handyman, or buy your neighbor a beer. As for that super loud, extremely annoying door close alarm that bothers the neighbors, perhaps they've toned it down. It beeps and a little LED light flashes. That's all there is to it. A power failure messes it up? I had it plugged into the wall for the setup, and disconnected it and moved everything for the final install. Nothing was lost. An extended power outage may be a different story, but how often does that happen? The device loses connectivity? Not that I have seen so far. Perhaps it's time to invest in a better router or access point? Chamberlain's support was/was not helpful? Chamberlain's support was not necessary. The device takes too long to respond. If nearly instantly is too long. My wife likes a clean garage. That means almost nothing is stored in the garage. Certainly nothing of value. But that also means this device received approval for it's clean, simplistic, nice looking install. Her words were, "Very nice." I'm happy. The wife is happy. What more could you want? I hope I've addressed all your concerns. Reading comprehension, hire a handyman or buy your neighbor a beer. That's really all there is to it. I was looking for something I read here regarding 16 bit AES. I didn't find it, but just to clarify, there is no such thing. 16 BYTE, however, is the key size for 128 bit AES encryption. I also read where a couple of people stated this damaged their opener. Hogwash! There is NO physical connection between the MyQ and the opener. The MyQ is nothing more than another "clicker" like what you have in your car now. The MyQ basically has three radios built-in. One communicates with your Wi-Fi router over 2.4 GHz, the second communicates with the door sensor, presumably over 900 MHz, and the third is the "clicker" radio. Since this works with most openers, it is universal and therefore uses multiple frequencies depending on which make/model opener you have. Saying it damaged your opener is like saying I turned on my car stereo and my dishwasher shut off. Others say they do this for a living and... take that with a grain of salt. I provide IT support for a living and I know some people that don't have a clue what they're doing. Who among you works in an office, knows their job, does it well, and knows someone that struggles with even the basics of the job? We ALL do! Giving the benefit of the doubt, perhaps they received a defective unit. It happens. But more likely it's a problem with the customer's router. Most garage door installers are not computer techs, just as most computer techs don't know garage doors. If there were a problem with the tension spring on my door, or if it somehow began to move at an angle and got stuck, I wouldn't have a clue how to fix it. I'd have to call a door company. Installing this device is on the technology side, not the physical door side of the business. If your door guy is stumped, thank him for his time and call an IT guy. There are many devices around the home that operate at/near/ or have harmonics in the 2.4 GHz band. I found cases where a poor connection at an outdoor lightbulb, and another where a failing Infrared night-vision security camera cause sufficient noise in the band to make communication impossible. Some LED and many fluorescent lights will cause similar interference. Many wireless routers are factory set on channel 6 for Wi-Fi. You may be surrounded by signals from all 4 neighbors operating on the same channel as your router. I have a laptop with specialized software that identifies those signals and gives me a real-time graph of their strength. A good IT guy can identify this and change the frequency of your router to a much clearer channel. This can be especially difficult in an apartment complex, but you are connecting a garage door opener, so it's much more likely you're not in an area as densely populated. To sum it up, those experiencing trouble likely have other IT problems on their end. This is not a fault of the MyQ, and not something a garage door company can likely solve. The MyQ is a very simple device that operates completely wireless, with the exception of one power cord. For 99% of the people reading this, that's a good thing. UPDATE: I have been using this daily for 6 weeks now. It has never dropped off the network. I did falsely alert once that the door was open when it wasn't, and twice it said it couldn't determine the status of the door. In each case, opening or closing the door reset it. The two times it couldn't determine the status were when I opened the app to open or close the door as I was about to drive through it, so no big deal. The false open alert was a little concerning, but I have a driveway camera on one side, and the door to the house on the other has an alarm. Neither showed any alerts of activity, so I knew all was well. Although this has me thinking a camera inside the garage might not be a bad idea. Is the door really open or closed? Did I leave a light on? I can simply view the camera on my phone or computer and be sure. If something WERE going on, I'd have it all on video. What's $30 for that extra peace of mind? I should also note that I do not work for Chamberlain, nor any of their child companies. I paid full price for my device. My review is based on my personal experience, expertise, and opinion. I do not receive compensation for any of my reviews, but I'm not opposed to that! How can I get in on this? Free products in exchange for an honest review? It seems too good to be true. ... show more
