After adding the M1S (flashed with custom firmware), many unadded devices appeared, and the newly added devices could not be recognized.

After adding the M1S, a total of 15 devices appeared, but my actual gateway only has 3 devices: one switch, one wireless switch, and one motion sensor.

No matter how many times I uninstall and reinstall, restart HA, try different versions, or delete and re-add the M1S, the issue remains unresolved.

Among these 15 devices, there are 13 switches, 1 wireless switch, and 1 vibration sensor.
