There is the companion App, which only updates every 15 minutes, and it doesn’t work over LTE network…
Using build-in browser(via shortcuts app), tried to display simple panel, no go. The build-in browser in Apple watch is limited, maybe problems of js engine, anyway, it will not login…so no HA lovelace…
One more thing I tried, appdaemon + dashboard add-on, same result, only label shows, no data… guess it the same problem due to watch browser limitation.
I am stuck, what else I can try? Thanks…
