As sparked by a discussion in an unrelated thread, I'm contemplating ways to integrate Alexa control of an arcade cabinet or RetroPie setup. Turning a cabinet on or off via Alexa is fairly straight forward if the device can handle being directly unplugged, slightly more complicated if we're looking to do soft on/off, but still doable with off-the-shelf components.
What I'm envisioning is directly launching a game by voice. The purpose being that while typically a front-end is going to have a short-list of games, you might have some large number of other titles available in an 'all games' category or some such which would be quicker to launch by naming the game rather than scrolling through a long list. Numerous times I've had a guest ask "Yes, but can it play X?" to which the answer is "Yes, but..."
At the moment I'm thinking this is accomplished by running something like NodeRED (
https://flows.nodered.org) somewhere on the network, and then a plugin on whichever front end which accepts commands over the network, generated by NodeRED.
