KWGT Android weather widgets

I have an Android widget I created on my phone that displays time, date, current weather and forecast for the next 4 days. I’m wondering if anyone knows whether it is possible (and if so, how) to obtain weather and forecast data from my Tempest weather station with that widget creator tool? Right now I’m using “Open Weather Map”. AccuWeather is one of the choices but you have to pay a subscription fee and I would still like to use my own weather station.
