Analysis

It is not possible to update platform accessories because the method handleUpdatePlatformAccessories() is not properly implemented:

https://github.com/homebridge/homebridge/blob/c25b3827a8ad2433083e93f3839255500d7478b1/src/bridgeService.ts#L388C3-L391

  // eslint-disable-next-line @typescript-eslint/no-unused-vars
  handleUpdatePlatformAccessories(accessories: PlatformAccessory[]): void {
    // Update persisted accessories
    this.saveCachedPlatformAccessoriesOnDisk();
  }

In this method, the array of PlatformAccessory objects is lost, as it is not used in the handleUpdatePlatformAccessories() method. The method just saves the currently cached platform accessories back to disc without updating anything.

Even worse, the method is commented with a sweep-issues-under-the-rug annotation:

  // eslint-disable-next-line @typescript-eslint/no-unused-vars

Expected Behavior

handleUpdatePlatformAccessories() should take the passed in array of PlatformAccessory objects and update the appropriate cached accessories before saving them back to disk.
