Need help accessing ring doorbell due to recent moveHello,I recently moved and don’t have access to the ring doorbell already installed at the home. I am unsure which model, no equipment to charge (not sure if battery powered but did hear low ring inside home) and can’t unscrew the security screws since I don’t have the tool. I also called support and they mentioned they need MAC address but can’t open doorbell. Can someone help or how can I unscrew? Thank you
