		"ups": {
			'cyberpower': {
				"driver": "powerpanel",
				"port": "/dev/ttyS0",
				"desc": "Cyberpower CP1500AVR"
			}

Note about listen ip addresses.

By default upsd listen on 127.0.0.1.

If you want upsd to listen to on other than 127.0.0.1 interface or more that only 127.0.0.1. Override this attribute in a role or environment.

	"nut": {
                ...
                        "listen": [
                                "127.0.0.1",
                                "192.168.1.1"
                              ],
                ...
                    }

Note about users.

If upsmon process must run in SLAVE mode, then set node attribute follows: "users": { "vagrant": { "password": "vagrant", "upsmon": "slave" } },

"upsmon master": false IS INVALID attribute in attributes setup.
