Reopening an old thread ...
Yes I can verify that Stringify actions to Wink shortcuts to open and close the MyQ garage door are blocked. A little silly.
Chamberlain now has a IFTTT interface but they charge $13 CDN a year subscription to enable the interface.
I tried it out but they limit the actions to;
Turn on light
Turn off light
No action for opening the door. Crazy.
I will look into the GoControl.
