The Used Vivint Sky Master Control Panel V-MP2-345 WiFi ZWave with battery is a white home automation module from Vivint. It includes a power supply control, keypad, and batteries. You'll have to supply the power wires, but the transformer plug is included.  The unit is wireless and features Wi-Fi connectivity. This indoor-only device is a crucial component for controlling your home surveillance system. The Z-Wave smart home protocol ensures seamless integration with other compatible devices for enhanced convenience and security.  I don't know any technical details of this unit, it was replaced with a newer version.  Unit powers up when battery is connected.
