Unfortunately it isnt possible to add a live stream in homey ( as far as i know )
but there are some 3th party tools / apps available like e.g. “hdashboards” ( [PRO][Dashboard] HDashboards a dashboard system fully focussed on Homey - Developers - Homey Community Forum)
with this tool you can create your own layout for e.g. a webbrowser / mobile phone / tablet , which do support livestreams
