Shelly DALI Dimmer Gen3 – Smart Built-in Dimmer for DALI Lighting

Smart WiFi Controller for DALI Lighting

DALI lighting offers professional dimming control but typically requires a dedicated DALI controller. The Shelly DALI Dimmer Gen3 replaces that controller and adds WiFi, Bluetooth, and home automation integration to your existing DALI installation. This allows you to smart control up to 5 DALI luminaires via the Shelly app, Home Assistant, or another home automation solution, without new wiring.

Power and Connectivity

The module operates on 110-240 V AC (±10%, 50/60 Hz) and requires a neutral conductor (N). Its own power consumption is less than 2 W. WiFi operates via 802.11 b/g/n at 2.4 GHz with an indoor range of up to 30 meters. Bluetooth 4.2 offers an indoor range of up to 10 meters and also works if the WiFi network temporarily goes down. The module also functions as a WiFi Range Extender for other nearby Shelly devices.

Functionality and Settings

The Shelly DALI Dimmer Gen3 functions as a single-master DALI application controller (DT6) and controls all connected DALI luminaires simultaneously via broadcast messages. Color temperature control (CCT) is not supported; only brightness control. The DALI bus guarantees 10 mA at a nominal bus voltage of 16 V and short-circuit protection below 35 mA.

In case of a power outage on the DALI bus, connected luminaires automatically switch to 100% brightness. Through the settings, you can set minimum and maximum brightness, a fade rate, a transition duration from 0 to 100%, and a night mode with a different brightness level. Two switch inputs (S1 and S2) support both switch and push-button operation for on/off and dimming.

Expansion and Accessories

The module is compatible with the Shelly Plus Add-on interface for external sensor expansion. Combine the DALI Dimmer Gen3 with other devices from the Shelly collection for a fully automated lighting system. Do you also want to dim non-DALI lighting?

Safety and Reliability

The built-in temperature sensor monitors its own operating temperature. The module features TLS 1.2 encryption for secure communication. Use is limited to indoors at -20 °C to +40 °C. ⚠️ The required circuit breaker has characteristic B or C with a minimum breaking current of 6 kA.

Home Assistant

The Shelly DALI Dimmer Gen3 integrates with Home Assistant via the Shelly WiFi integration.

1. Connect the module to your WiFi network via the Shelly app or web interface.
2. In Home Assistant, go to Settings > Integrations. The module will be automatically discovered via mDNS, or you can enter the IP address manually.
3. After pairing, a light entity for brightness control (0-100%), an internal temperature sensor, and a power sensor will appear.
4. Local control via the HTTP RPC API is confirmed. Cloud connection is optional and can be disabled.

⚠️ The module controls all connected DALI luminaires as a single group. Individual addressing of separate DALI luminaires via Home Assistant is not possible with this module.

Homey

The Shelly DALI Dimmer Gen3 works with Homey Pro via the official Shelly app from the Homey App Store. The connection is local via WiFi. Via Homey Bridge, pairing is only possible via the Shelly Cloud. Zigbee and Matter are not applicable to this device.

Other Platforms

• Google Home: compatible via Shelly cloud
• Amazon Alexa: compatible via Shelly cloud
• Apple HomeKit: not natively supported, but via third-party integrations
• Samsung SmartThings: compatible via Shelly cloud
• Domoticz: compatible via MQTT or the Shelly HTTP API
• KNX: supported via KNXnet/IP

Automation Examples

Automatically dimming lights at sunset

1. Connect the Shelly DALI Dimmer Gen3 to Home Assistant via the Shelly integration.
2. Create an automation with trigger: sun sets (offset: +15 minutes).
3. Action 1: set the light entity to 40% brightness via service light.turn_on with brightness_pct: 40.
4. Action 2: add a second step that dims to 10% for mood lighting at 23:00.
5. Save and test via Developer Tools > Actions.

Lighting schedule with presence detection

1. Add a motion sensor as a trigger source in Home Assistant.
2. Trigger: motion detected in the office.
3. Condition: time between 07:00 and 22:00 and brightness lower than 200 lux via a light sensor.
4. Action 1: switch on the DALI lighting to 80% via the light entity.
5. Action 2: set an automatic switch-off timer of 15 minutes without motion via a timer helper entity.

Points of Attention

• ⚠️ The neutral conductor (N) is mandatory; installation without a neutral conductor is not possible.
• The module functions as a single-master DALI controller and does not share the DALI bus with other DALI masters.
• Maximum 5 DALI control gear units on the bus with guaranteed 10 mA bus current.
• Color temperature control (CCT/DT8) is not supported; only DT6 (brightness control).
• In case of a DALI bus fault, all luminaires switch to 100% brightness.
• Not suitable for outdoor use.

Frequently Asked Questions

How do I connect the Shelly DALI Dimmer Gen3 to Home Assistant?

Connect the module to your WiFi network via the Shelly app or web interface. Home Assistant automatically detects the device via mDNS. Go to Settings > Integrations and accept the notification, or enter the IP address manually. After pairing, a light entity will appear, allowing you to set brightness. More information can be found in the Home Assistant collection.

Do I need a hub?

No. The Shelly DALI Dimmer Gen3 connects directly via WiFi 2.4 GHz to your home network. A separate DALI controller, hub, or subscription is not required. For use with Home Assistant, the built-in Shelly integration is sufficient.

How many DALI luminaires can I connect?

The module guarantees 10 mA bus current, which is sufficient for a maximum of 5 DALI control gear units. With more luminaires or higher bus current demand, the bus may be overloaded. Always check the power consumption of your DALI luminaires in the manufacturer's datasheet. Short-circuit protection activates at currents above 35 mA.

Can I control luminaires individually?

No. The Shelly DALI Dimmer Gen3 controls all connected luminaires simultaneously via broadcast messages. Individual DALI addressing per luminaire is not possible. If you want to control separate channels, check out the other dimmers and modules in the assortment.

Does the module also work without WiFi?

Local control via the two switch inputs (S1/S2) always works, regardless of the WiFi connection. Smartphone control and home automation integration require an active WiFi connection. Bluetooth offers a limited fallback for local control via the Shelly app within a 10-meter range.

Does the DALI Dimmer Gen3 support color temperature control?

No. The module only supports DT6 (brightness control). Color temperature control (CCT, DT8) and RGB control are not supported. For smart lighting with color control, check out the lamps and light sources in the assortment.

Is the neutral conductor mandatory?

Yes. The Shelly DALI Dimmer Gen3 requires a neutral conductor (N) for power supply. Installation without a neutral conductor is not possible. This distinguishes the module from the regular Shelly Dimmer Gen3, which also works without a neutral conductor with a bypass.
