Thank you for letting me know more details about this!
I would advise you turn the Hub off and leave it off as this could be a fire risk.
I have booked an engineer appointment for you so we can take a look at your equipment. You can manage your appointment through your online account. If you need to reschedule this due to any Corona virus symptoms, this can be done through the same link.
Please keep us updated on how your appointment goes and if you need any further help.
That's great to hear @Gavla50 and thank you so much for letting us know. Hopefully the new Hub should fix the issues you've been facing but should they continue at all please don't hesitate to let us know back here on the forums!
