This is possible using Voice Monkey (VM) but also with TRIGGERcmd (TC). VM maybe easier to setup for this but I don't use it.
Since I use TC and have been playing with the different TC skills I knew there should be a way. As it turns out you can call a TC configured script with a curl call.
Even better the developer created a tool "tcmd" which makes this even simpler.
You can even add this inside a script and adding this to the end of a script you can trigger the call and even make it depending on the results.
I started playing with time and found Alexa sees the time call as a button press and this allows you to use the routines to have Alexa respond with any number of things.
So I tried creating a simple virtual TC script that just echoed OK ( nothing fancy ) I then created a routine that had Alexa play a song on my office dot when that device was tripped. Back in my raspberry command line I typed " "sudo ./tcmd -t dummy.sh" (dummy.sh is the name of my virtual script) I got a message trigger sent OK and in my office Alexa started playing music
I'm sure VM can do the same.
Although I have set this up with HG on a Pi, I know you could set this up with any HA software. The tcmd tool and TC will work on any OS.
