If you’re just using IFTTT, you can use Google calendar for the “this” and a smartthings virtual switch for the “that” and then trigger smartthings events to happen because of the switch coming on:
Echo and Google home only recognize some device classes, specifically lights, switches, thermostats , and maybe locks.
The official SmartThings/Alexa integration can run routines, but only routines that are limited to the device classes above.
IFTTT has the same issue. The SmartThings service/channel can turn a single device on or off, but it doesn’t show routines or modes or smart home monitor status.
So how can you use your voice assistant or IFTTT to change your mode, unlock a lock, or change smart home monitor armed status if the voice assistant/IFTTT won’t work with those kinds of devices?
Fortunately, it’s easy.
But these days I think most people would use webcore:
CoRE (now WebCore) is a very powerful community – created rules engine for SmartThings. It allows you to set up stacked conditionals like “If A then B but only while C and not if D.”
Setting it up can be quite complex, but there are many community members who will be glad to help you.
For example, here is a piston that one member created to notify him if the dog had already been fed twice that day and he picked up the dog bowl for a third time. He needed this because he has a large family and people didn’t always remember whose turn it was to feed the dog.

At one point, one of the biggest advantages of using the SmartThings platform was the wide variety of devices that it supported. However, by the end of 2017 several competing platforms had caught up in that regard.
Where SmartThings still holds a significant advantage over some of the other low-cost home automation solutions is in the ability to really build really complex rules in a fairly simple manner. You won’t have to be a programmer, but you may need the help of other community members to get the logic constructed just right.
