I am highly interested in following this thread. I implement home automation in my home, and currently my vintage gear power is switched, through automation, using Ubiquiti Unifi smart power strip. ESP32 is used extensively within Home Assistant as well, and within many other smart devices on the market. The point is, when designing this solution, look at compatibility with smart home interfaces using off-the-shelf technology. I can tell you after having a smart phone for 20 years, I simply tire of having to rely on it solely to control devices. Automation ability with Home Assistant, Alexa, Google, etc, would be a nice value add. I would certainly buy the Vintage Control Center in a heartbeat, most likely as a standalone device, but more so if implemented as a modern piece of gear.
