I have no power to my Zwift hub, no flashing blue LEDs let alone a solid blue one. I have tried all troubleshooting tips to no avail. Has anyone else had this problem?
Could be the power supply. You tried checking the fuse?
Yeah mate, tried the fuse too.
If you (or a friend) have a multimeter, I would check if the power supply is producing something like the expected values. That might save you the trouble of returning the entire trainer unnecessarily.
