MMM-SunnyPortal Solar Module

 Hi Snake-Darkangel, Did you use the latest code listed at https://github.com/linuxtuxie/MMM-SunnyPortal ? More specifically the piece of code listed in the file node_helper.js is important. SunnyPortal seems to be very picky when it comes to the browser which makes a connection to there website. I recently updated the user-agent to the latest Firefox version as shown below: headers : { 
 // We need to simulate a Browser which the SunnyPortal accepts…here I am Using Firefox 82.0.3 (64-bit) for Windows
 ‘User-Agent’: ‘Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:82.0) Gecko/20100101 Firefox/82.0’,
 },User SkyFocusNL even used another user-agent to get things working

 maybe you can give that solution a try and provide us some feedback ?Regards,
