Hello, dmitryvit.
Thank you for using Apple Support Communities.
From what I've read is that you're not being able to record and the motion detection isn't working. I'd like to help. It's good that you've already confirmed the requirements have been met. Just to confirm, are you able to live stream with the cameras and have you checked the settings on each camera?
According to Logitech's FAQ, the cameras will only record when motion is detected. With that being said using wireless set up, the motion detection works differently than the wired setup. Take a look at this article: When does Circle 2 start recording?
"Wire-Free Cameras
While attached to a battery and in battery optimization mode, Circle 2 operates differently. The camera uses the low power motion sensor (a passive infrared sensor or PIR sensor) to detect activity in its field of view. Similar sensors are used on motion-activated night lights.
Using the low power motion sensor allows the camera to keep the video sensor, which may drain the battery, in sleep mode. When the low power sensor detects motion, the video sensor wakes up, which triggers recording. Recordings occur in 10, 30 or 60-second intervals before the video sensor goes back to the sleep mode.
If the camera is already awake (e.g. if you are watching the live stream), the camera will automatically use the video sensor to determine relevant motion and manage recordings without needing to use the low power sensor first.
You can adjust the sensitivity of the low power motion sensor to ensure you are capturing the moments that are relevant to you. From the Settings menu, tap More Settings to edit the Motion Sensitivity.
NOTE: If you're using the Circle 2 Wired camera or placing the camera on the Window and Plug mounts, motion detection will work through glass. If you're using the Wire-Free camera, it relies on a low-power sensor for motion detection that doesn't work through glass".
To answer your other question, there isn't a way to debug the HomeKit. You may need to contact Logitech support for further help.
Let me know if this helps.
Best regards.
