It looks like the custom stream channels are focused on streaming video types only. Is it possible to stream an active website? I have 2 use cases for this, one being the ADS-B flight tracking site. I'd like to have that viewed on a TV via a "channel". The other is a Grafana dashboard that refreshes every few minutes.
Both are straight up web sites and I haven't been able to find good alternatives to the RPi running a headless Chrome process.
