Nine business lines · One engineering bench

Hardware, software, and the apps that tie them together.

Raywise is an integrated house — we design the controllers, source the components, write the firmware, build the cloud, and ship the mobile app. The nine business lines below are how we package that capability for our customers.

Every project starts with the same conversation: what are you trying to control, and who needs to see it? The rest is engineering, sourcing, and shipping. Browse the nine lines below — each one is a real team at Raywise, with a real track record, and a real mobile app on the App Store and Google Play.

01

Smart Control Systems

PLC, SCADA, edge controllers, and HMI panels — engineered for industrial-grade reliability. We design control logic, commission on site, and stand behind it for the life of the line.

  • PLC programming and retrofits (Siemens, Allen-Bradley, Mitsubishi)
  • SCADA dashboards, alarm rationalisation, historian integration
  • Edge controllers with secure remote access
  • Functional safety reviews and CE / UL documentation

02

Industrial Automation Products

From a single motor starter to a full robotic cell — sourced, integrated, and commissioned. We carry the parts and we know the people who make them.

  • Variable-frequency drives, servo systems, soft starters
  • Robotic cells (pick-and-place, palletising, machine tending)
  • Vision inspection and quality-control loops
  • Pneumatic, hydraulic, and electromechanical subsystems

IoT Device R&D & Technical Services

Connected devices, edge firmware, and the cloud they talk to. We do the schematic, the layout, the enclosure, the MQTT bridge, and the OTA update pipeline.

  • Hardware design (schematic, PCB layout, EMC-aware enclosure)
  • Embedded firmware (C / C++ / Rust, FreeRTOS, Zephyr)
  • Telemetry pipelines (MQTT, HTTPS, LoRaWAN, NB-IoT)
  • OTA update infrastructure and fleet management

Software Development

Web, mobile, desktop, and the back-end that holds it all up. We ship production code, not slide decks.

  • Web apps (React, Vue, server-rendered)
  • Mobile apps (native iOS, native Android, cross-platform)
  • Back-end services and APIs (Node, Go, Python)
  • DevOps, CI/CD, observability, and SLOs

05

Automation Equipment Sales

New and refurbished automation equipment, with the documentation and warranty you'd expect from a Tier-1 vendor and the price you'd expect from a Hong Kong trading house.

  • PLC, HMI, drives, sensors — new, surplus, and refurbished
  • Brand-agnostic sourcing (Siemens, AB, Mitsubishi, Omron, Schneider)
  • 12-month warranty on every line, with on-site commissioning available
  • Export documentation, certificates of origin, and customs handling

Electronic Components Sales

From a single MCU to a full BOM. We stock the long tail, source the hard-to-find, and ship with traceable paperwork.

  • Active and passive components, MCUs, sensors, connectors
  • Authorised and independent channels; traceable to manufacturer
  • BOM optimisation, alternates, and obsolescence management
  • Same-day quote on stocked lines; 2–6 week lead on custom

Technology Transfer & Consulting

Move a process, a recipe, or a know-how package from one geography to another. We handle the paperwork, the engineering, and the on-site training.

  • Process transfer (semiconductor, electronics, biotech, food)
  • Equipment transfer, refurbishment, and recommissioning
  • On-site training, documentation, and standard-operating-procedure writing
  • IP assignment, licensing, and confidentiality frameworks

Business Information Consulting

Market entry, supplier search, regulatory mapping, and competitive intelligence for the Greater China and Southeast Asia corridors.

  • Market entry and partner search (Asia, EU, North America)
  • Supplier audit, due diligence, and quality-system review
  • Regulatory mapping (CE, UL, FCC, CCC, RoHS, REACH)
  • Competitive intelligence and benchmarking
