Hi Folks … I looked without any success for a reverse logic momentary button that is always on until you press it and then it is off briefly and then back on. I needed this because I need to tell Alexa to turn off my TV using a momentary button. Without this I have to tell it something that doesn’t sound like English like… “Alexa, turn on TV off” which is stupid. So I wrote this device type which simply reverses the logic of a virtual momentary button. Then I assign it to a Harmony action that turns all entertainment devices off. Here is the code for the device type. To use this just make a new device and assign this type, and then write your smart app referencing it. Don’t forget to add it to Alexa and do the Discover New Devices thing. Enjoy.
