I think the PSU on one of my sets is broken. Plugging it in and hitting the power button does nothing, and there's no status LED light. If you open the app, you can't toggle power using the app BUT hitting the power button on the PSU will toggle the switch in the app, so it's not totally dead. Yet it still doesn't power my panels. Should I just replace my PSU? I would swap it out with the PSU on my other set to see if it really is the issue but let's be honest, these things are so finicky that I'm not willing to take that risk of something breaking if I unplug my working panels.
