About Us

Giving buildings a soul through technology

Xiamen Yijia Smart Technology Co., Ltd. has spent 14 years in smart systems, audio-video and lighting design — covering 100% of Fujian province and delivering projects nationwide. We combine the engineering discipline of a systems integrator with the aesthetic judgement of a lighting designer, providing one-stop service for premium residences and high-end commercial spaces: product selection, system planning, lighting design, installation, commissioning and after-sales — all delivered in-house, end to end.

Milestones

A verifiable record of work — more reliable than marketing claims.

2013

The team was founded around a dual capability — systems integration plus lighting design: engineering discipline alongside aesthetic judgement.

2019

Began publishing professional content systematically; our Toutiao channel 'Yijia Smart AV & Lighting Design Service Centre' has run ever since.

2021-2026

166 published works covering project walkthroughs, installation footage and buying guides — a verifiable public record.

To date

The Aoogee Xiamen showroom is featured on SmartCN (14 showroom photographs); the Tmall Qianwen / Tmall Genie whole-home ecosystem partnership is in place, forming five mixable product lines with KNX, Tuya, Aoogee and RS-485.

Capabilities

Four Core Capabilities

Five product lines in parallel

KNX bus (domestic and imported), Tuya ecosystem, Tmall Qianwen ecosystem, Aoogee and RS-485 (domestic and imported) — one team qualified across all five, mixable per project and never tied to a single brand.

14 service lines

Smart home, lighting design, sensing, wireless network, surveillance, motorised shading, background music, building automation, security, home cinema, KTV, golf simulator, smart hotel and smart office — covering residential and commercial scenarios alike.

One in-house team, end to end

From product selection, system planning and lighting design through installation, commissioning and after-sales — everything is delivered by our own team. No subcontracting, no outsourced installation.

Documented delivery

Every project is handed over with point drawings, configuration tables, an equipment list and as-built documents; an approved drawing set is issued during construction and after-sales requests are logged and tracked.

Residential and contract, both in-house

Not just homes. Office buildings (Wangsu Technology, 22 storeys / 44,000 m²; Walton Group HQ, 2,000+ m²; Ronggang Port Terminal, 5,000 m²), hotels and clubs (Guanyinshan Splendid Regent, Gulangyu Qinsheng, Xinfuxing Clubhouse), AV integration, KTV sound and lighting, indoor golf and smart office are all delivered. Contract work follows operational and procurement standards; homes are refined around scene experience.
