Since the new Fuchsia OS firmware update on nest hub (1st Gen) the default timeout for casted webpages before going into "ambient" mode has been reduced to 30s. It used to be 10 minutes before timing out.
This causes issues using the Nest Hub as a dashboard for home automation (Home assistant) through chromecast, but also is an issue if you want to show something like a recipe website for longer than 30s.
It takes longer than 30s to cook things, and I can't keep touching the screen while cooking.
Can the inactivity timeout default be increased to 10 minutes again?
Yes, what's also odd is that even when I ask google to open a webpage directly "Hey google, open abc.net.au/news" it doesn't timeout with inactivity...
If only I could ask google to open a local IP webpage...
Devs have confirmed that it is not an issue with CATT or pychromecast. So either Fuchsia or home assistant app.
