I thought this was an interesting blog post from Yonomi about the best tech for an Airbnb rental. I would agree with their choices but would add one more: Amazon echo.
Yonomi is a free third-party app that provides IFTTT type functionality for a specific list of devices. There are some community members using it particularly for Sonos and harmony integration, but it doesn’t itself work with SmartThings.
Their blog highlights devices they do work with, but it often has interesting articles on Home Automation topics that apply to any platform. Like this one.
