Hub 3 red light

Joining in

I wonder if you could help. My hub 3 has exactly the same problem as others in this group. It is showing a red light and it doesnt clear when rebooting or hard reset. The light has been present for three-ish months and the wifi can be patchy for work when it had been very stable in the past. It is no-where near any central heating is cool to touch and is open on all sides so can’t see why it would be overheating. 

Any ideas gratefully received.

A persistent red light on the Hub 3 should mean a replacement Hub.  This is the overheat warning and if it is faulty, then it is a risk.  It has nothing to do with your patchy wifi.

A VM Mod should pick this up in a day or two and discuss.

Hi @Andy103 👋.

Thanks for reaching out to us. In the event of a red light appearing on your Hub and following the process for maintenance:

• Turn the power switch off on the back of the Hub.

• Ensure the Hub is upright, in a well-ventilated location, and, if at all possible, out of direct sunlight.

• Then use the power switch to turn the unit back on. The Hub should now operate normally.

Should the red light persist, then we would need to bring you into a private message so that we can confirm a few details and get this sorted out for you. 

Could you please confirm if you have followed the steps above?


Hi Sabrina,

Thanks for getting in touch. I have done as requested and the red light remains on.
