One focus for over a decade

Who we are

Nantong Yihua Intelligent Technology Co., Ltd. was founded in 2007 and incorporated in 2012, with registered capital of RMB 10 million. We are an authorised distributor for GVS Smart, LEADED, Miyue Background Music, D-CONTROLS, SEEDLINK and Beile — all main products supplied through the original manufacturer channel, with selection design, programming, commissioning and after-sales warranty included.

We hold a Grade II qualification for electronic and intelligent engineering contracting (China's second-class ELV contracting licence) and operate a team of three certified KNX engineers, including two advanced-certified engineers and one KNX tutor. As a member of CSHIA and the operator of the GVS Smart Home whole house experience centre in Nantong, we deliver design, installation, commissioning and lifetime maintenance in one accountable contract.

What we do

Our business covers smart lighting, KNX smart home, home cinema and AV and ELV building systems. Projects range from residential communities, shopping malls, hotels, cruise ships, factories, airports and hospitals to private villas, duplex apartments and single-level residences — each with a solution engineered for the site rather than a fixed package.

Our service network covers the whole of Nantong and clients nationwide. We work with KNX as the backbone because it is the only open international standard for residential and building control — multi-brand compatible, and every KNX-certified engineer in the world is trained on the same protocol.

Why KNX matters to an international client

If your project is outside China, interoperability is not optional. KNX devices from different manufacturers share one bus, one addressing scheme and one engineering tool (ETS). A system commissioned by our engineers in Nantong can be handed over to a local integrator, extended later, or integrated with third-party HVAC, lighting or access-control systems without replacing the controller.
