@anon63427907 now the integration works well. Thanks for all so far!
I test the following setup:
| device | ringing | flash light | motion detection | person detection |
|---|---|---|---|---|
| eufy doorbell 2k wired | ✓ | - |  |
✓ |
| eufy floodlight cam 2 pro | - | ✓ | |
|
mean I was not able a register a state switch in Home Assistent. For motion/person detection I modify the settings of eufy floodlight cam 2 pro (detect persons/detect all motions). I can confirm that the camera it self detect each event successfully (see screenshot).
Is it possible that the integration do not support the eufy floodlight cam 2 pro?
I work as a software developer, if I could help you (at least with testing) to improve the integration, let me know.
