When something is not right, describe the symptom clearly and leave the rest to us.

Technical Support

Three ways to report a fault

Phone is fastest; message and email are better for keeping the detail. Choose whichever suits the situation.

Service line

+86 513 83598898 — for fault reporting and warranty or maintenance enquiries. Calls are answered fastest.

Technical support

+86 151 62768261 — for business and technical questions. Send a message if a call is inconvenient.

Service email

214405310@qq.com — send the fault description with site photos or video so we can judge in advance.

Process

How a repair request runs

Four steps from report to closure, with someone following each one.

01
Intake
Call or email with the symptom, the location and a contact; we log it and open a record.
02
Remote diagnosis
By phone, remote debugging or video we identify the fault point; most problems are resolved on the spot.
03
On-site handling
Where site work is needed we attend at the agreed time, replace spare parts or adjust the program, and explain the cause.
04
Follow-up
After the work we call back to confirm the system is working, and keep the record for later tracking and maintenance.
Technical support and remote diagnosis

Before You Call

What to prepare before you report a fault

The more specific the information, the faster we can locate the problem. In most cases, if you set out the points below clearly, we can identify which stage the fault is at without needing to attend.

  • Project name and address

    So we can pull up the construction and commissioning records for that project.

  • The specific symptom

    For example, all three living room circuits are out, or the panel buttons do nothing but the backlight is on. The more concrete, the better.

  • When it started and any pattern

    Sudden or gradual? Did it follow a power cut, redecorating, or the replacement of a network device?

  • How much is affected

    One panel, one area, or the whole home or floor? This directly sets the direction of the investigation.

  • Site photos or video

    Panel indicator lights, the state of the distribution board, any error message on screen. A photo is often more accurate than a description.

    • Remote or On-site

    Remote or on-site?

    Remote or on-site

    Changed parameters, broken scene logic, a control panel or gateway dropping offline, the app failing to connect, and scheduling or time-sync problems are all software and configuration issues, handled by remote debugging or by talking you through the steps.
    Circuit faults, damaged hardware modules, an abnormal bus power supply, a panel needing full replacement, and cable damage caused by construction all need on-site testing and replacement. We attend at the time agreed in the contract.
    The site network must be reachable and the KNX/IP gateway online. With your authorisation we can then connect remotely to investigate. If the site network is down, it needs to be restored first, or we will guide you by phone instead.
