Since Eufy seems to have started the public release of the firmware to enable Homkeit in Eufy Indoor Cam 2K, I can post this information based on feedback from a Beta tester using [22.214.171.124](https://126.96.36.199) Firmware.
To get the Eufy Indoor Cam that works with Homekit without anything being registered or notified by the Eufy App for iOS 13 (but iOS 14 Beta Testers indicates that nothing is different).
In the Eufy Security application:
In each camera setting (wheel icon for each camera)
1. Motion detection: Turn on
2. Recording settings: Disable
3. Notification settings: ENABLE all checkboxes.
In each camera view (where a live image is displayed)
1. P&T Motion Tracking: In the camera view, set your home position with arrows, click the Tracking icon at the bottom. Exit Camera View.
In Security settings (on the Home security tab) choose the camera, then tap the mode wheel icon if it is selected, and then deselect all options.
