 "summary": "The DKN Plus Interface is a Wi-Fi controller that wires to a single Daikin indoor unit (P1P2 or S21 connection) and also acts as a BACnet MS/TP slave on its RS-485 port. It exposes 12 objects: on/off, setpoint, room and return temperature, mode, fan speed, louvers and error status. The manual carries Airzone branding and its PICS names the vendor as ALTRA S.L.; the BACnet address is set from the DKN Cloud NA app.",

  "The object list marks Speeds (MV 1) R/W, while the detailed description calls fan speed read only.",
  "Localtemp (AV 1) is writable only on a P1P2 connection; on S21 it equals the return temperature.",
  "Temperature units are not stated in the object list.",
