While there are several different ways to have Alexa control basic devices within Home Assistant (such as lights,) but I'm not really seeing a lot out there to have more control over TV's (Samsung) and Pioneer Receivers (Onkyo) for voice control. This site looks like it can possibly do it, but I can't find a forum or other means to interact with others that have used it Introduction — Node-RED Smart Home Control documentation
If anyone has used this, can come up with a suggestion on how to get voice control over the above items within Home Assistant or can give me some guidance on how to set this up, I'd appreciate it. These would be basic things such as turn on the TV and receiver and it powers on both of the items, as well as volume up/down and muting capabilities.
