Hello, could someone tell me if it is possible to receive information in node red through an Ethernet port?
I have a scale in room A, which is quite a distance from room B, and I can't use a RS232 cable, that's why I was considering connecting the scale via RS232-ETHERNET adapter, in order to connect it to a siwtch /router and be able to read the gateway through the switch or router. or failing that, use an internet cable that allows me to cover more distance,
1 such solution is to use an off the shelf serial server that will present the rs232 device as a device on a TCP/UDP network. These can be a little expensive but equally you cou use an esp32 or similar SBC and relay the serial data over the network
As I said before, the answer is almost always yes.
