ELPM-S3LW development kit: €149 / certified version: price TBC
What it does
One controller. The whole room.
LUMA-6CH brings six power channels, two data ports, per-channel monitoring and open protocols into one professional controller for monochrome, RGB, RGBW, Tunable White and addressable lighting.
Configuration, scenes and energy data stay on your local network. No mandatory cloud, account or mobile app.
Choose LUMA-6CH when one controller must handle several 12–24 V LED lighting types, keep working without the cloud and integrate on the local network. It is not a mains-voltage lamp dimmer and requires a DC power supply sized for the connected load.

One controller, different applications
Coordinate functional and decorative light in residential and hospitality spaces, manage zones and energy in offices, control low-voltage circuits in gardens and pools, and keep operating locally where connectivity is unreliable.
Hidden source / clean ceiling
Interiors
Cove and downlights on one device: the source stays out of sight, the ceiling stays clean.
Independent zones, one controller
Offices
Continuous ceiling runs: cooler, focused white over the desks, warmer over the lounge, two temperatures from one cabinet.
Warm scenes, on cue
Hospitality & retail
Layered coves and lamps in warm white: each mood saved as a scene and recalled from a button or a schedule.
Every tread lit
Gardens & paths
Steps and walkways with the strip recessed in the profile: you see the light, not the fixture.
Integrated around the water
Pool & outdoors
Low-voltage perimeter light recessed in the coping: clean around the water, controlled from the browser at luma.local.

Why LUMA
More than a conventional LED controller.
LUMA-6CH combines multiple lighting types, per-channel electrical monitoring, secure MQTT and a REST API. It is configured from a browser and runs scenes, effects and schedules locally: no mandatory account, cloud or app. KNXnet/IP and BLE sensor-driven automations are planned for the commercial version and will be stated as available only after validation.
A concise comparison to support initial selection. Competitor specifications and prices can change: always verify the manufacturer's current official documentation.
The 384 W values are calculated at 24 V from the stated 16 A limit.
Encryption is not exclusive to LUMA: Shelly documents MQTT with mTLS by uploading the certificate and private-key file to the device, while Casambi documents an encrypted mesh using AES-128, ECDH and replay protection. LUMA's stated difference is hardware-backed credential protection: identities and private keys remain isolated in the crypto IC and are used for mTLS authentication and secure identity in the BLE domain. BLE link encryption is performed by the nRF54L15 radio stack.
Comparison checked 20 August 2026. LUMA's €149 price refers to the pre-certification development kit based on ELPM-S3LW; the certified commercial version's price is still TBC. Other prices are indicative averages converted to euros and subject to promotions and market changes; power supplies, gateways and infrastructure are excluded. YES means a stated capability; NO* means the capability or service was not present in the device documentation reviewed. The configuration method identifies the tools required for initial commissioning: Casambi requires its app, Loxone requires Config software with a Miniserver, and MDT requires the ETS environment with a KNX interface; Shelly also supports configuration through a local browser. For DALCNET, the required tools depend on the DALI or DMX-RDM variant and the level of configuration needed. Configuration times are not published because they depend on the installation, installer experience and acceptance-test scenario. LUMA items marked TBC depend on final configuration.

The €149 development kit uses ELPM-S3LW. The commercial version intended for certification will use the Espressif ESP32-S3-MINI-1 module and a dedicated nRF54L15 with a PCB antenna. The nRF54L15 connects wireless sensors and controls to local automations; compatibility will be stated for each supported sensor.
The whole interface is a browser dashboard at luma.local. No app on every phone, no account to create, nothing in the cloud.
A dedicated cryptographic element protects device credentials and keeps critical keys separate from application memory.
Setup wizard
From box to first light
Power it and open luma.local: the wizard walks you through name, Wi-Fi and light layout in four steps. No app, no account.
Guided identification
Know which channel you are configuring
From the wizard, blink an individual output to identify it, then assign its name, function and group without tracing cables through the cabinet.
Channels
Every channel, one screen
The dashboard lines up one tile per channel, RGB groups included, each in its live colour: state, brightness and the real current draw in watts. Because it meters every channel, a failing strip or a miswired run shows up as a number, not a mystery. One tap switches it, one tap opens the detail.
Control
Colour, effects, brightness. Live.
One tap turns a light on. The detail view holds colour, white balance, effects and the dimmer; every change applies instantly, from any browser on your network.
Automation
Scenes that live on the device
Scenarios run on the controller, not in the cloud: an external rocker or push-button, a door sensor, motion, or a calendar (time of day, days of the week, specific dates) can drive any light or group. Enable, disable or run them with one tap.
Measurements
Measure every channel
LUMA-6CH shows voltage, current and power for every output alongside system totals, making abnormal loads and wiring issues easier to identify.
Backup
The whole setup is one file
Export the full configuration as JSON: name, layout, channels, scenarios. Restore it after a swap, or copy it to the next LUMA-6CH in minutes.

FAQ
Questions, answered.
When can I get one?
The €149 price refers to the pre-certification development kit based on ELPM-S3LW. The certified commercial version is planned with the Espressif ESP32-S3-MINI-1 module and a dedicated nRF54L15 radio; final price and availability will be confirmed before pre-orders open.
Does it need the cloud, an app or an account?
No. You set it up from the browser at luma.local, on your local network: no app to install, no account to create, no cloud. If the internet goes down, your lights keep working.
Which lights can it drive?
Mono, Tunable White, RGB, RGBW and addressable LED, at 12-24V DC: 6 power channels (up to 180W each, 500W total) plus 2 data channels for addressable strips. There are also two inputs for wall rocker switches: the lights stay controllable from a plain switch, even with no network at all.
Does it integrate with Home Assistant or Node-RED?
Yes. LUMA-6CH supports MQTT and a local REST API, without a mandatory cloud or account. It can integrate with systems such as Home Assistant and Node-RED while operational data remains on the owner's network. Endpoints, authentication and examples are available in the LUMA API documentation.
How does it connect to sensors and building systems?
The commercial architecture includes an nRF54L15 for Bluetooth LE sensors and planned KNXnet/IP integration. Application-level BLE sensor support and KNXnet/IP remain in development and will be declared available only after validation. Secure MQTT and the local REST API are already part of the current software architecture.
Will it comply with the Cyber Resilience Act (CRA)?
LUMA is being designed with CRA requirements in mind, but final compliance will depend on the commercial hardware, production firmware and conformity process. The current development platform already uses a crypto IC for non-exportable identity keys, MQTT mTLS and mandatory signed OTA verification. Secure Boot, Flash Encryption and the complete BLE security domain are not yet enabled in the current build.
What am I committing to by joining the waiting list?
Nothing. You get one email to confirm your address and one when pre-orders open. No payment, no obligation to buy, and you can remove yourself at any time.
