Jackpot!!!
A quick update and I finally think I figured it out, at least for MMM-OpenWeatherForecast by:

• Subscribing to Open Weather’s One Call by Call (https://openweathermap.org/price)
• Changing my node_helper.js line 44 from 2.5 to 3.0 :

var url = https://api.openweathermap.org/data/3.0/onecall?"

Thanks again and I’ll share on the other thread as well. “https://forum.magicmirror.builders/topic/17644/a-working-weather-module”
