I can control the volume of my individual Amazon Echos using an input_number component that calls a shell_command. See here for an example.
However, this requires me to update the authentication data periodically when it stops working.
I’m using the Emulated Hue Bridge in Home Assistant. Is there any way I can use the existing Home Assistant hooks into the Amazon Echo service to change the volume on my Echo so that I don’t have to update my script?
