Thanks for this comment! I didn’t see the new update until I saw this.
In the app itself, the tags aren’t listed, but they do work now.
The Tag Expressions web page has them listed, but there seems to be a mistake.
They need to be written as a plural, e.g., forecastHours(index, String) and not forecastHour(index, String). Same for Forecast Days.
They also support arithmetic expressions, so you can show or hide weather icons based on the forecast
