The PWS_Dashboard ( aka HWS-template) already supports multiple weather-programs and website-API’s.
It now also supports the WetherFlow api for those owners that will not or can not run a weatherprogram 24/7
The WeatherFlow-API is used to get the realtime data, the dashboard itself creates the high/low history.

To avoid confusion:
This template has no relation with and is not using data from https://www.pwsweather.com/
