PARKOO Dehumidifier PUBLIC Integration

Select PKO-DEHUM-21309-PUBLIC to connect the device through KC11. This generic profile provides telemetry, parameter operations and feedback without customer automation, notification groups or site locations.

Wiring and preparation

Use continuously powered Class C, RS-485 9600, 8N1, and default polling address 1. Match A/B wiring to the nameplate and manufacturer protocol. Install the EdgeBus application for 21309 / v3 and check regional radio settings. Selecting the template does not install firmware or change the dehumidifier's panel address. Polling addresses are 1–247.

Daily operation

Inspect fresh temperature, humidity, power, fault and timestamp values before changing power or the humidity setpoint (10–99). Temperature setpoints are 10–65 °C. Fan, compressors, heater and coil states are available; disabled coil probes do not produce valid temperatures. Power state is not proof of compressor motion.

Writes and feedback

A power command writes once and queues one read 10 seconds later, within a total 30-second observation window. A write acknowledgement is only an acknowledgement. Confirm the actual result from a valid read or fresh report. Missing, expired or failed communication means unknown/unconfirmed, with no automatic repeated write. Serialize transparent operations per device: the protocol has no request ID, so identical delayed replies can remain ambiguous.

Sampling and location

Defaults are 60 seconds for sampling, 300 seconds for uploads and 900 seconds for the collector heartbeat. These intervals are independent. Temperature/humidity COV defaults are 1 °C / 2 %RH; SET includes one collector reset. Faster sampling adds serial load; faster uploads add radio traffic. Use readback for actual values.

The 3D-location action accepts a location object containing scene_id, model_id, coordinate_system, unit and x/y/z position. Read back _location_3d; this does not change the formal location assignment.

Acceptance scope

PUBLIC resources were published and read back. Physical actions, natural acquisition cycles, business MQTT, persistent logs and application waiting states still require field acceptance. The complete integration gate retains failed or environment-blocked checks; catalog availability is not end-to-end acceptance. Configure alarm and automatic-control policies separately.
