Hey guys
I know that this topic is not completely right in this forum but my hope is that a network expert can give me an answer.
I'm creating a new project with an ESP32:
I want to read all my systems at home (heating system, electricity meter, water meter, ...) via modbus tcp and than write it into my database via API. For the hardware I chose an ESP32. I don't want to use the wifi interface.
So can I do it with only 1 ethernet port? If I'm putting a switch infront?
i appreciate your help
Thanks
As long as all devices are in the same IP subnet and physically connected to each other (via switch) it should be simple. If they are in different subnets, a router is required.In any Cass, 1 Ethernet port is sufficient.
