Hi.
I use the digital inputs of the Cerbo to monitor the state of some relays. This obviously works as long as the relay to monitor are close to the cerbo.
Does anyone know another way of doing that? For example
-with an external usb/ethernet board (kind of like the ethernet/usb relay boards but monitoring connections instead of switching relays)
-maybe with a raspberry pi and some of its accessories?
Thanks
john
