## What is PM50?

Keep an eye on your smart plant floor wherever you are. Set up, manage, control, and monitor your PM-50 smart panel meter– all from your PM50 by Red Lion App. 

PM50 by Red Lion lets you securely connect to and control your PM-50 smart panel meter remotely. The User Interface is identical to PM50 Device’s User Interface for a seamless data management experience. With this app, you can connect to all of your PM-50 devices one at a time. Simply connect to your device in the IP screen using the PM-50’s IP address (found in the about device section on the device) while connected to your plant wifi, and you will be navigated to the home screen where you can oversee your plant.
