I just timed it, and it took 4 seconds from opening the MyQ app to being able to open my garage door. The only time I experience the load times you’re talking about is when I’m connected to my house WiFi far enough from the house that I don’t really have any internet connection at all anyway.

MyQ is probably the best $30 I’ve ever spent.

I’m under no illusion that that APIs are appropriately handled, or that it’s great for all workflows. But for me, it delivered the expected functionality, no RPi hacking required.
