Do I need to plug in the ProWeatherStation?

The TP3000WC ProWeatherStation Console can run on 3 AA batteries and the included AC adapter. To enable the Wifi functionality the unit must be plugged into the adapter. The batteries can be installed in the unit also to act as backup power.

-The Outdoor Sensor array runs on a total of 2 AA batteries but is mostly powered by solar so the batteries last a real long time.

-The connection between the sensor array and controller is wireless.

-The connection between the Display console and the computer is via the Wifi connection.

-The controller connects to your wireless router and the computer connects to the wireless router via WiFi or Ethernet cable.
