Thanks for your post on our Community Forums burhan01ads, and a very warm welcome to you!
Sorry to hear of the issues you have been experiencing with the red light on the Hub 3.0.
Can you please confirm if the advised pin hole reset has been performed, and did this resolve this issue?
Alternatively, if the pin hole reset has not been successful, can you please power down the hub for 30 minutes and allow the hub to cool,
Then reboot this up to see what colour light populates.
If this remains red, we will seek to replace the hub with a like for like swap via an engineer visit.
Thanks,
David_Bn
