Capabilities

Capability Matrix

Where the company does the work itself, and where it depends on a third party. Each entry cites what the supplier published.

Dimension	Capability	Evidence
Hardware Design	In-house	The official website states that the HP-40S uses a self-developed temperature-control system and describes proprietary compressor, airflow, panel, and structural configurations across several product lines (Source 2).
Firmware	No	No source provides evidence that the company develops its own device firmware, embedded software, or firmware team; the published references to smart humidity sensing and a smart ecosystem do not establish firmware ownership (Sources 2 and 3).
Manufacturing	In-house	A P2 company profile explicitly describes the business as combining production manufacturing, technology R&D, and sales and service, and identifies two production bases totaling 25,000 square meters; the official site also reports a new-factory construction project (Sources 2 and 3).
Cloud / App	No	No source identifies an independently developed cloud platform or mobile application; the official site's reference to a full-home smart ecosystem is insufficient to establish proprietary cloud-app capability (Source 2).
