A dairy farm system comprises a plurality of apparatuses (11a-e) for performing actions related to the operation of the dairy farm system, wherein the apparatuses are connected in a network (12), and at least one of the apparatuses (21, 26-28) is movable. The movable apparatus is wirelessly connectable to the network via a short-range radio link (23a-c, 26a-c, 27a-c, 28a-c), preferably a Bluetooth link. Advantageously, the movable apparatus is kept continuously connected in the network (12) via the radio link during operation. In one embodiment the movable apparatus is a feed device (21), wherein feeding instructions are received, and feeding status or error information is sent, by the feed device via the radio link.
