Sorry to hear about this, @kclommen! It definitely sounds like the Spotlight Camera is not powering up, as a reset and setup attempt did not result in light indicators. When pressing the setup button, as you know, the bottom should flash and the Camera will likely announce setup mode audibly.
As you’ve already charged the battery completely, please also check the battery hatch for any debris as well as ensure the hatch is closed securely. If the Spotlight Cam still does not respond to setup mode, and a setup will not complete in the Ring app, the best next step will be to reach out to our support team. Please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
