30 The Aquaero devices expose eight physical, eig

35 For the D5 Next pump, available sensors are pu
36 and current, as well as coolant temperature an
37 available through debugfs are the serial numbe
38 count. Attaching a fan to it is optional and a
39 temperature curves directly from the pump. If
40 sensors will report zeroes.

42 The pump can be configured either through soft
43 interface. Configuring the pump through this d
