Hi i have been using butons to trigger Echo Speaks to say thing in a different voice for a while now. But i have noticed you can select the default tts voice in settings
Echo Speaks does not utilize Hubitat’s native TTS engine. For that, you’ll need to use a natively supported TTS device like a Sonos or IKEA Symfonisk speaker.
Thanks, I already to this and trigger it with buttons from rule machine. I was hoping to do it directly in RM. It's a pity RM does not allow markup when you pass values to custom actions.
