Duplicate Outlets for HS105
Hello,
I am on the latest version of this Plugin, and basically, I have 3 HomeBridge instances. Even though I only have the plug/outlet listed in only 1 of the configs, if the other bridges restart, a Plug is added to the other bridges despite there being no mention of it in the config for those bridges.

If it doesn't make sense basically I have 3 bridges. Only 1 has the plug in the config, yet all 3 add the plug. 

My config for the bridge the plugin is added to:
```
{
	"bridge": {
		"name": "Homebridge",
		"username": "CC:22:3D:E3:CE:30",
		"port": 51826,
		"pin": "031-45-154"
	},
	"description": "Homebridge",
	"accessories": [{
			"accessory": "DummySwitch",
			"name": "Living Room Switch",
			"stateful": true
		},
		{

			"name": "MasterBedroom Switch",
			"stateful": true
		},
		{
			"accessory": "RaspberryPiTemperature",
			"name": "CPU",
			"updateInterval": 1000
		}

	],
	"platforms": [{
			"platform": "Bond",

			]
		},

		},
