I use a lot of “Simulated Alexa Switches” - a custom developed Device Handler by Brian Pierron
It is described here: [Release] Virtual Alexa Switch/Button
NOTE:
After examining the FAQ link mentioned by JDRoberts and drilling down to the “theSmartcave” article theSmartCave, it turns out it also recommends the Brian Pierron device handler.
(I started using the “Simulated Alexa Switch” back in December 2018)
