Hey tuiceman, thanks for the input but it's important to note that Follow up mode must be enabled AND only works within 5 seconds from the first [named] command.
It was created to help with questions/commands in sequence and not to serve as a 'conditional' as you're probably assuming.
"Currently available on all Alexa-enabled devices, including the Echo, Echo Dot, and Echo Spot, this follow-up mode only works if Alexa is absolutely “confident you’re speaking to her, Amazon says. So be sure to ask your follow-ups quickly — you have just five seconds between the end of Alexa’s response and the start of your follow-up to hold the smart assistant’s attention. You can tell whether or not Alexa is still listening to you and ready for your next query if her blue indicator light ring remains on. Once it switches off, you’ll have to say her wake word again.
In order to get this functionality to work, you’ll actually have to turn on follow-up mode for Alexa. As Amazon notes in its customer service page regarding this new feature, you’ll need to go to your Alexa app, then select settings from the menu. Select your device, and then scroll down to follow-up mode and toggle it on (it remains off by default). Of course, Amazon must note that “While Alexa is active, your questions, requests, and related information are processed in the Cloud.”
