In all seriousness, @ogiewon, @cwwilson08 and hopefully @mike.maxwell are working on a way do TTS with Alexa. I'm hoping that they get that going, because so many of us are longing for that capability from Echo. I bought a Google Home Mini and used @ogiewon 's port of Google Assistant Relay to send TTS to it. Works great and although I don't have a need for the added ability to send silent commands to it, I am looking forward to having that at the ready when it's needed to control a device that Hubitat and IFTTT don't support yet, and for which a cloud connection is acceptable.
I'm hoping this silent command capability might also come from their research into the Echo TTS capability. There was one such capability with Echo at one time, but Amazon shut that down.
