I am trying to control an Elk output using ISY portal. So I can turn on and elk output using Alexa. I am presently using two zwave switch. When switch is turned on my elk program will open or close elk output. This will cause the actuator on my pet door to open or close. I'm hoping there's an easier way to accomplish this. I'm very familiar with the elk products not so much ISY. Zwave I/O modules cost more than zwave switches and I don't think Alexa will work with them.Thanks for your help
