Frequently asked questions

First check that the bus power supply and the power to the circuit are normal. If only some buttons have failed, the usual cause is a cable that loosened during earlier decoration or maintenance, or a panel address that was changed. Record the specific symptom and when it started, then contact us — it can usually be located remotely.

First establish whether it is one scene or all of them. If only some are affected, the parameters of that scene have probably been changed or overwritten by another scene; if all are affected, check whether the gateway and control devices are online. Tell us which panel, which scene, what was expected and what actually happened, and we can check the parameters remotely.

Some control devices need power-retention parameters configured, or they rely on network time synchronisation. Check the power and configuration state of the gateway and control devices; reloading the project program restores the system if needed.

Yes. KNX is an open standard and extends through structured line, area and domain topology. New panels, sensors or actuators only need to be connected to the bus and given an address. We can assess the point capacity and distribution capacity against the drawings first, then provide a scheme and quotation.

Provided the project has a KNX/IP gateway connected to the local network, device status, scenes and operating records can be viewed from the control panel or management platform. With your authorisation we can also connect remotely to investigate, without a visit every time.

Nine out of ten dimming problems come from the driver and the dimming method not matching. Raise the minimum brightness parameter first, then check the driver minimum brightness setting, whether a single channel load is below the power threshold, and whether the dimming method (DALI, 0-10V or phase-cut) matches the driver. Where necessary, replace the driver with one that supports deep dimming.

Yes, but one principle applies: use fixtures and drivers with the same dimming method on the same dimming circuit. Mixing phase-cut dimming with digital dimming such as DALI leaves some fixtures uncontrollable or flickering.

Check the local network status and the gateway power in turn. If the router or broadband line has been changed recently, the gateway network parameters usually need reconfiguring. Once the subnet and port settings are confirmed, remote assistance will normally restore it.

There are two common causes: the gateway is still using the old subnet or IP address and is not on the same network as the new router; or the router has AP isolation or a guest network enabled, so the phone and the devices cannot reach each other. Tell us the old and new router models and we can guide you through changing the configuration back.

These functions depend on network time synchronisation and online data. Confirm the site network is working and the gateway can reach the internet. After a long power or network outage, restoring the network and synchronising the time once is enough.

Yes. You can sign an annual maintenance agreement, or book a visit as needed. Charges are settled against the actual work done and the spare parts replaced — quoted first, carried out afterwards, with no mid-job price rises. See the warranty and after-sales page for details.

Talk to us before work starts. The KNX bus is usually run in the same conduit as mains power, so moving walls, replacing the distribution board or adjusting the ceiling can all affect the cabling. Getting the drawings and point schedules before construction avoids a great deal of rework; cable damage caused by a later fit-out is normally outside the warranty.

Yes. The registered address and the smart experience centre are both in Chongchuan District, Nantong, and the team is permanently based here. Survey, detailed design, construction and commissioning for homes, villas, commercial spaces, parks and factories are all handled locally. We also take on projects outside the area, with travel and programme costs stated before the quotation.

It depends on the area, the use and the degree of customisation. On a typical home, once the drawings and points are confirmed, the ELV work proceeds floor by floor, with equipment installation and joint commissioning after the main cabling is done. Finished villas and commercial spaces take longer. An accurate programme is given after assessing the site and drawings — we do not make verbal commitments.

There is no uniform price list that holds regardless of the site. The budget varies widely with the area, the number of points, the control method (panels, control panel or voice), whether AV and shading motors are included, and which product lines are chosen. Send us the floor plan or your requirements and we will prepare an itemised scheme and budget range. Pricing is transparent, with no low teaser price followed by additions.

Yes, and it is often the more practical starting point. Smart Lighting on a KNX bus with DALI or 0-10V dimming works as a system in its own right, and shading, HVAC linkage and security can be added later. The system is designed on an open standard, so the interfaces reserved for later are not wasted.

Yes. KNX is an open standard extending through structured line, area and domain topology. New panels, sensors or actuators only need to be connected to the bus and given an address, and devices from different brands interoperate. What does need attention is the cabling limit and the distribution capacity — leaving headroom at the planning stage is far less trouble than retrofitting later.
