Interface Raspberry Pi with Ethernet relay

Hello, just bought model raspberry Pi 3+ and trying to connect ethernet relay board though able to connect through some physical connection easily but port connection are not compatible and was looking for some suggestion to create the connection between both ethernet,
Anyone who worked and lead me to the better example will be very useful

Hi Frank,

I haven’t seen these relay boards before, but on the website they say that they are “permanently married” and that they use “custom firmware”. Both of those terms and the lack of documentation makes me think that these devices will be very difficult to interface with. They communicate over a standard network, so if you figure out their communication protocol then you should be able to just connect them all to the same network to communicate.

I hope that helps! Good luck with your project!
