RE: Gateway USB and Gateway Ethernet
I am attaching a diagram of the mysensor part of my installation.
At the moment, I have the cellar's ethernet gateway working.
The usb gateway also works but only towards the 4relais card which controls my 3D printer, The card which controls the mechanical ventilation of the ground floor no longer works.
If I remove the cellar gateway The card that controls the mechanical ventilation of the ground floor works again.
