Product System

Products by Service Line — 14 Sections

Yijia is a systems integration provider, not tied to any single brand. The smart home section is split into five product lines by protocol and ecosystem; the other 13 sections are specified by scenario. Different sections can be mixed within one project.

Smart Home

Smart Home · Five Protocols & Ecosystem Product Lines

For long-term stability and open protocols, choose KNX, choose Tuya for fast delivery and a controlled budget, Tmall Qianwen for natural interaction, Aoogee for hands-on local trials, and 485 bus.

KNX Bus Protocol ProductsApplication photos
01

KNX Bus Protocol Products

Domestic + Imported

KNX Bus Products

The European standard bus architecture — an open protocol since 1990 where devices talk to each other directly, with no cloud in between. It keeps running when the internet drops, and equipment installed thirty years ago still shares the same bus with today's devices.

  • Wired bus mixed with wireless deployment
  • Device-to-device control, no cloud dependency
  • Cross-brand compatibility, unified ETS configuration
  • KNX-Secure data encryption supported

Best for: Detached mansions, high-end clubs and five-star hotels — projects held for the long term

Tuya Smart Ecosystem

Tuya Smart Ecosystem

A complete IoT ecosystem covering lighting, sensing, shading, HVAC and AV control. Deeply integrated with the Tuya cloud, it is the best answer when you need fast delivery at a controlled cost.

  • Full-range ecosystem devices available
  • Continuous cloud OTA upgrades
  • App and mini-program control
  • Deep integration with our own control panels

Best for: Mid-to-high-end homes and volume projects where speed and a controlled budget matter

Tmall Qianwen AI Ecosystem

AI Interaction

Tmall / Qianwen Ecosystem

An ecosystem built around AI voice and natural-language interaction: control shifts from pressing switches to simply saying what you need. Measured scene understanding means long-tail commands no longer require memorised phrases.

  • Natural-language scene control
  • Multi-turn dialogue for complex commands
  • Works with Tmall ecosystem appliances
  • Supports smart speakers and control screens

Best for: Homes, clubhouses and show flats where natural interaction matters to a younger audience

  • Physical showroom in Xiamen for hands-on trials
  • In-house lighting sandbox and live scene demos
  • Local team with 24-hour response
  • Design and commissioning delivered by one team

RS-485 Bus Products

Domestic + Imported

RS-485 Bus Products

A wired bus solution with controlled cost and high stability, suited to budget-sensitive projects that still require reliable interlocking — large-volume rollouts and subsystem integration.

  • Lower cabling cost than KNX
  • Long-distance, interference-resistant transmission
  • Compatible with mainstream control protocols
  • Ideal for HVAC, shading and other standalone subsystems

Best for: Large areas, many subsystems, cost-sensitive volume and retrofit projects
