Have you reached out to the tomorrow.io team to see if they have any suggestions on how to make their widget auto refresh?
Yes, they basically suggest doing basic javascript to reload which I have tried, but the challenge there is that the authentication failed message pops up.
Would this be solved having a refresh interval setting for the custom tile itself that would refresh the SharpTools iframe?
I’ve run out of ideas so for now I’ve switched to WeatherWidget and used your suggestion for the refresh. Not the widget I want, but will work until I can possibly work out a solution.
