Hello Luke198824
Sorry to hear of the hub issues and red light experienced by your friend, we understand the concern this can cause and appreciate you contacting us on their behalf via the forums.
Please can you ask them to try this for us:
• Turn the power switch off on the back of the Hub.
• Ensure the Hub is upright, in a well-ventilated location and out of direct sunlight, if possible.
• Switch the hub back on at the power. The Hub should now operate normally.
Please report back with the result. Do you know if they have been in touch with the team?
Rob
