Hi Dstuk75
Welcome to the Community Forums.
Sorry to hear of your concerns with the red light on your Hub 3. Usually this is just an LED error rather than anything more concerning. But we'll err on the side of caution and book an engineer to investigate further for you. Please join me on private message so I can locate your account and pass account security.
