Hi @chrispix! Thanks for reaching out!
When the quirkbot is fully charged, the orange charge indicator light turns off. And if you have it switched on and plugged in, it would start drawing some power again, so the battery would start charing again, turning on the red light.
But the "No Quirkbots detected" message seems to be an indicator that something could have gone wrong with the quirkbot. The first thing tro try is to try to reset to the factory settings,
So try to follow this guide and let me know if there is any progress.
