Short description
Shelly DALI Dimmer (the Device) is a gateway device between Shelly ecosystem and APIs and a DALI network of lights. It can control DALI capable light sources that contain DALI control gear.
In terms of DALI it is a single-master application controller, supporting LED control gear (Part 207), which does not share the bus with other DALI control devices. Shelly DALI Dimmer controls all connected DALI control gear as a single group with broadcast messages.
The Device contains a bus power supply with possibility to control up to X non-powered bus units.
The Shelly DALI Dimmer can be accessed, controlled, and monitored remotely from any place where the User has internet connectivity, as long as it is connected to a Wi-Fi router and the Internet.
It has an embedded Web Interface which can be used to monitor and control the Device, as well as adjust its settings.

Webhooks: Support automation through lightweight, event-driven communication with other devices.
BLE Gateway: Facilitates communication between BLE and Wi-Fi-enabled devices.
Wi-Fi Range Extender: Retransmits the Wi-Fi signal and extends its reach.
Scripting: Allows creating automation scenarios through scripts.
Compatibility: Highly compatible with 3rd Party home automation systems.
KNX: Supports KNXnet/IPcommunication
No need for hub: Ready for use locally or remotely via Shelly Smart Control or 3rd Party systems.

What are the differences between the different generations of Shelly products?
Each new generation adds more power, memory, and features:
Gen 1 offers basic control;
Gen 2 (Plus Series, Mini Series, Pro Series) adds Bluetooth, scripting, and better security;
Gen 3 improves performance, adds Matter (starting from firmware version 1.6.0 or newer) and advanced monitoring;
Gen 4 offers multi-protocol connectivity, featuring Wi-Fi 6, Bluetooth, Zigbee, and Matter.
Can I control the device via Bluetooth?
No, the protocol is used only for device inclusion, allowing for quick and easy setup through the Shelly Smart Control app.
For bluetooth control it is required to have another Bluetooth device such as Shelly BLU Button or Shelly BLU Motion to interact.
Additionally, Shelly devices can function as a BLE gateway, bridging Shelly BLU devices to your Wi-Fi network.
Is it possible to use the device without a hub?
Yes, Shelly devices (except for Wave devices) operate independently without the need for a hub. They connect directly to your Wi-Fi network, and you can control them via the Shelly Smart Control app, web interface, or through integrations with platforms like Google Home, Alexa, Home Assistant and Samsung SmartThings.
