Amazon Echo devices to control the Roon server with voice commands

So there is absolutely no need to have the hub anywhere near any equipment, nor to use the FLIRC to make a connection with any particular equipment - it just needs to be connected with wifi? I assume that connection is made through the Harmony app? That app wasn’t “seeing” the hub, so I’m not sure how to tell the hub which network to use or the password.
I keep thinking… Couldn’t all this be done with software (no hub)? I, for one, would gladly pay a reasonable price for such a product.
