@savan

I cannot help you on your OPC question. But I'm going to advise you to **secure your Node-RED instance right now**.

You have exposed it to the internet with **no security** applied. If it has access to your devices, then you have **exposed them to the internet** as well.

You have blurred the IP address of your instance in the address bar, your ip address is still visible in that screenshot in the chrome tab.
