Crestron Programming
for Hong Kong's High-End Residences
We are a Crestron Certified Programmer based in Hong Kong. We write the control logic that ties your home's lighting, climate, AV, shading, and security into a single elegant interface - and we keep it running long after install day.
Built in-house: SMARTL
Most of what you see on the touchscreens in the residences below is SMARTL - our own React + TypeScript control interface that runs natively on Crestron touch panels, in the browser, and as an installable PWA on any iPhone, iPad, or laptop.
It speaks to the Crestron processor over a multiplexed WebSocket protocol we wrote, survives iPad sleep/wake without losing state, and caches the room's configuration locally so the lights are responsive within a second of unlocking your phone.
Currently running in production at multiple Hong Kong residences - and you can try the exact same interface in your browser below.
Try SMARTL in your browser
The same control interface running in our clients' homes today, with a sandbox configuration you can poke at freely. No signup, no install, no real home behind it.

Why our Crestron work is different
We code it ourselves
Most "Crestron dealers" in Hong Kong resell hardware and outsource the programming. We are the programmer - your control logic isn't hidden in a black box you can't touch later.
We ship our own UI
SMARTL is our in-house Progressive Web App - no app-store install, runs on any phone, tablet, or laptop. The same interface used in production at residences across Hong Kong today.
We design for the next ten years
Local-first communication, open web standards, and source you can hand to anyone. No vendor lock-in to us specifically. If we go quiet tomorrow, your home keeps working.

Frequently Asked Questions
Common questions from homeowners, designers, and project teams before we touch an existing or new Crestron system.
Can I try SMARTL before contacting you?+
Yes. There is a live demo at demo.smartl.app that runs the same interface deployed in production homes, with a sandbox configuration. It works entirely in your browser - no backend, no signup, and each visitor gets their own private session.
Can you take over an existing Crestron system?+
Yes. We can inspect the current processor, program files, network, and device list, then advise whether to repair, refactor, or rebuild the control logic.
Do you only work on new luxury residences?+
No. New builds are ideal, but we also handle upgrades, troubleshooting, UI refreshes, and partial integrations for existing homes.
Will we own the source code and configuration?+
Yes. We believe the home should outlive any one vendor. We can hand over documented source, device mappings, and operational notes.
What systems can you integrate with Crestron?+
Typical projects include Lutron lighting and shading, Samsung Frame TV / The Wall, Bang & Olufsen audio, Daikin or Mitsubishi HVAC, IP cameras, intercom, smart locks, and network gear.
What ongoing support do you provide after handover?+
We can support commissioning fixes, scene adjustments, iOS/PWA setup, certificate renewals, processor updates, and future room or device additions.
