Could you enable the debug mode, so I can get more information about the loaded config. It seems like the accessory initialization process has been triggered more than once.

But this may be related the cached accessory info in homebridge, so you may try to remove the accessories and the persist contents and reboot homebrige.

I removed the cached accessory and it seems to have cleared the error. Thanks.
