It would be really useful to be able to trigger a scene from IFTTT. There is currently not really any good way to turn multiple devices on or off with an action. You can have multiple actions on IFTTT Platform, but you cannot add the same action more than once so it doesn't work if say you have 3 single switches you want to control.
I notice scenes show up in Google Home as devices but not IFTTT so maybe part of the work is already done?
Is there any development still going on for the IFTTT integration? I had to go back to using the Smart Life compatible devices since there is no way to turn more than one of yours on/off at a time.
