You can do the same thing with IFTTT (trigger a Hue scene).

And in both cases, you can do the complicated logic over on the SmartThings side and then turn on a virtual switch/sensor, and have that switch coming on be the “if” in either an Alexa routine or an IFTTT applet.
Unfortunately, there’s a bug right now with the Alexa/SmartThings integration, and the triggers are not working for all people all the time, which is very frustrating. I don’t know if the same issue is affecting Ifttt or not, I haven’t seen any reports on that.
