Alexa Helper - Change mode or phrase with a switch toggle

Are you sure you have the 3 pieces installed:

Alexa Helper-Parent: Sounds like you have done this
Alexa Helper-Scenario: You will SAVE it, but don’t publish it
Virtual Dimmer Code: You will only need this if you want to use the thermostat or speaker functionality. This is not an app, but a new device.

Let me know…also, I am releasing new code today. This should not affect you, but you may want to go to the official thread for this and ensure you have the latest versions.
