I have been successful using Stringify —> IFTTT —> Smart Life.
Overall things work fine for individual lights or groups. I have a total of nine lamps controlled by smart life plugs and have a group defined as Smart-AllLightGroup. When I leave for the day and the Off command gets triggered, it misses two or three of the lights.
I originally thought it might have been colliding with traffic from my wink hub which is doing other lights and the door lock so I tried inserting delays and the order of things, but no luck.
I just modified the Smart Life into multiple groups and now will triggger from Stringify with three separate IFTTT actions to Smart Life and give it a try.
Has anyone else ran into a limit here? If I go into the Smart Life app and turn on and off the group of nine lights, all respond accordingly.
