All values are polled through the network (UDP) by munin. You can even watch some live readings here. The board is designed to be stacked on top of another expansion PCB and provides the following functionality itself: an ethernet connection via W5500 an OneWire connector (3.3v, GND, Data) an EEPROM socket (AT93C46W via DIP or SOIC) temperature…
