I serendipitously stumbled on this item while perusing Amazon for a remote garage opener for an old Sears Craftman opener. Boy, am I content to have accidentally discovered this item. It has converted both my Chamberlain garage openers to a useful smart system. I brought two as Amazon renewed items in order to have two garage sensors since I have a three-car garage with two garage openers. The extra hub will be as backup. I got a decent deal vs getting them as new items. One was brand new & the other one was somewhat already used by the previous owner because the garage sensor already had the adhesive tape attached & a little dirty. However, they both seem to be working without any issues. I guess this is what is expected with renewed items. It was packaged well & shipping was relatively quick despite not being a prime member.The installation was somewhat agonizing because of my complicated network setup. I don't use a traditional off the shelf router. Instead, I use a third-party, open-source firewall as my router... running on a typical desktop computer with many managed switches & AP's. This powerful network setup allows me to have a plethora of subnets & Vlans, which allow the ability for the segmentation of the network. This provides additional security by not allowing less secured devices, e.g., IoT's, from interacting with other secured devices on the LAN. After hours of trial & error, MyQ finally connected to my complex network. I had to temporarily disable client isolation & roll back the security protocol from WPA2/WPA3 to WPA/WPA2 of the UniFi [Ubiquity LR WiFi-5] AP. However, after successfully connected, I re-enabled both client isolation & the higher security protocol, WPA2/WPA3. It's working fine after a week of testing. Some reviewers say one must create a separate 2.4 ghz netwok with WAP/WPA2 only. This suggestion seems to be incorrect because it's connected & working on a dual band (2.4 & 5GHz) SSID with WPA2/ WPA3 enabled. I refused to create a less robust netwok (SSID) just for MyQ because I want all my IoT's to be on the same netwok so I can easily monitor them with the Unifi controller software. It seems the main factor that matters the most is the strength of the WiFi signal to the MyQ hub. One way to increase the WiFi signal strength without having to move equipment, is to increase the width of the WiFi signal if your WiFi offers this option. For example, the 2.4 ghz & 5 ghz were increased from 20 mhz to 40 mhz & 40 mhz to 80 mhz, respectively. This made a huge difference. The hub is much more stable now after this adjustment despite the fact that AP is more than 50 ft from the garage with many obstacles in between the hub & AP. Word of caution, this option could create connectivity issues for some networks. In general, Ubiquity AP's are more powerful & flexible than the typical WiFi device.The app is wonderful for the most part. To install, you just download the MyQ app & follow the directions. Easy peasy if you have a basic network. It may be a little harder if you have a complex network like mine. The app works as intended for the most part, but it has a couple minor issues that can be frustrating. 1. Tired of the frequent password login requests when biometric login is the only option enabled in the app. The biometric option isn't always consistent even when it's successful because there are occasions when a password prompt page still pops up. When that occurs, I have to tap the top back arrow for access, weird.🤔2. General notifications work great but I can't seem to get the "schedule" option to work. I want the garage door to close automatically at a certain time at night in case I forgot to close it. There are times when the garage door was left opened overnight. Don't want strangers, especially animals looking for a warm comfortable place to rest for the night as if it's a hotel. I live in a relatively safe, gated community in a cul-de-sac. There are strange animals roaming the place at night. My biggest fear is stumbling on one of them in my garage. Thus, this is an important feature [schedule] for me that I would love to see working.Overall, this is an awesome system that will convert the typical garage door opener into a useful smart device.Update <4/22/23>: The "schedule option" is now working for me, yippee! It appears this option will not activate if the scheduled "time" is the same for both garage sensors. Problem solved after staggering the time for both sensors. This is a nifty feature. 🥰🤗
