1. A dialysis system comprising:
a water treatment device including a water treatment processor, the water treatment device fluidly connected to a water source and configured to provide purified water; and
a dialysis machine including a dialysis machine processor, a dialysate holding tank, and at least one dialysate mixing pump connected to a source of concentrate, the dialysis machine processor communicatively coupled to the water treatment processor for preparing dialysate using the purified water provided by the water treatment device, wherein the dialysis machine processor is configured to:
receive an indication that a batch of dialysate is needed,
transmit a first message to the water treatment processor to begin providing the purified water,
cause the at least one dialysate mixing pump to pump a concentrate from the source of concentrate for mixing with the purified water to form the dialysate for storage in the dialysate holding tank, and
after the batch of the dialysate has been stored in the dialysate holding tank, transmit a second message to the water treatment processor to stop providing the purified water.
