I have had the previous version of the MyQ hub and with garage door sensors which provided sensing and control for my two legacy (not wifi) liftmaster garage door controllers. I could separately monitor and control each of my two garage doors. The system worked fine for about a year - until it didn't. A couple of days ago, I received some unknown error about a sensor (I wish i'd have taken a shapshot) on my phone - with a message to press the button on my sensor. I did - and the whole system went south. One of my garage doors was gone from the menu. I now found out how BADLY the software has been architected.
Because of the way the app is written (iphone), I couldn't just remove the devices and re-install them - because my devices aren't available to select in the app as separate devices. The only way that the devices were visible is through the INITIAL setup routine. SO I I had to reset EVERTYTHING and start from scratch (reset the hub, add a sensor, link with garage door opener, add another sensor, add another controller. And I had to step through ALL OF THE instructions on how to mount the devices over and over again. What a pain. The software writers took the easy way out - at my expense. But that wasn't all.
Finally, when everything was done, BOTN of my door openers respond SIULTANEOUSLY to ONE door's commands. It appears that there is insufficient logic in the app or system or software to deal with the fact that my openers already had been linked to the MyQ. The software ended up linking each door to a COMMON signal. I am now going to have to totally reset both of my garage door openers, program my remotes, and then program myQ. I am hopeful that after a couple more hours of hassle, it may all work again. Lazy programmers = a lot of wasted time if you ever have to change something.
