@Saabman Thanks for sharing your experience ! I will absolutely take your suggestion and start poking around. As I’m new to MM, I wanted to get an operational dashboard up and running and now that I have, I can go and see if I can get WU to work as you’ve suggested.
My current workaround to get my weather station data into MM is via Home Assistant (HA). I have a plug-in for HA that brings WU data into my HA dashboard. I’m using the MMM-HomeAssistant module to push that over to my MM dashboard.
