Chris Habe das selbe Problem das mein Hub kein Strom abgibt probiere gerade das mit den 30 min aus hat jemand vielleicht eine Lösung?
Igor I have tried many options with no success so I raised a ticket sometime ago and I wait for a new hub2000 now
Igor If nothing worked for you then I suggest quickly creating a ticket where you should explain the problem. Zendure support at the end should replace your hub2000 (the procedure took a month in my case)
