I created a FauxMo (https://github.com/n8henrie/fauxmo) plugin so that I could initiate a macro on my ReefPi (https://reef-pi.github.io/) aquarium controller.
I set up an Alexa Routine (https://www.amazon.com/alexa-routines/b?ie=UTF8&node=21442922011) so that all I need to do is say, "Alexa, feed the fish", which initiates my macro (which turns off the recirculation pumps for 10 minutes) amd also triggers the automatic fish feeder.
Both this FauxMo + plugin and my fish feeder are recognized by Alexa as smart home devices that can be turned on or off.
