Short description

Shelly Dimmer Gen3 (the Device) is a smart dimming controller which allows remote control of dimmable lights and dimming drivers through a mobile phone, tablet, PC, or home automation system. It can work standalone in a local Wi-Fi network or it can also be operated through cloud home automation services. The Device can be accessed, controlled, and monitored remotely from any place where the User has internet connectivity, as long as it is connected to the Internet. Shelly Dimmer Gen3 has an embedded Web Interface which can be used to monitor and control the Device, as well as adjust its settings. The Device can be used as trailing edge dimmer switch, with or without neutral wire.

Main features

No need for neutral: The Device can be used without neutral wire
Bypass: Bypass is required when the device is used without neutral and the load is under 20 W. Bypass could help when there is light coming from the lamp even when it is turned off.
Groups of lights: Groups of lights can be used, but they should have the same consumption (should have the same model and producer)
Bluetooth: The Device complies the Bluetooth standard and can connect with other Bluetooth devices to exchange data in short range.
BLE Gateway: Facilitates communication between BLE and Wi-Fi-enabled devices.
Wi-Fi: The Device can connect to a wireless network.
Wi-Fi Range extender: Retransmits the Wi-Fi signal and extends its reach.
Scripting: Allows creating automation scenarios through scripts.
Basic Schedules: Supports weekly schedules and routines, including setting of brightness, transition duration, and flip value of the dimming signal.
Аdvanced Schedules: Supports detailed schedules and routines throughout the year with a broad range of time adjustments from seconds to months, including setting of brightness, transition duration, and flip value of the dimming signal.
Auto on/off timers: Enables auto on/off timer setting.
Local actions: Allows creating automation scenarios within the local Wi-Fi network, including setting of brightness, transition duration, and flip value of the dimming signal.
Webhooks: Supports automation through lightweight, event-driven communication with other devices.
Compatibility: Highly compatible with 3rd Party home automation systems.
No need for hub: Ready for use locally or remotely via Shelly Smart Control or 3rd Party systems.
Activity log: Stores detailed history of events.
KVS (Key-value storage): KVS service provides a basic persistent storage of key-value pairs.
Safety: Оver current/voltage/power protections. When the device is used without neutral wire, those protections might not work properly.
Power measurement:
- Information about voltage (V), current (A) and consumption (W) is displayed when the device is used with neutral.
- Power consumption cannot be measured when the device is used without neutral.
Night Mode: Enables to set a specific brightness of input lights during nighttime.
Transition duration: Controls the time for dimming from 0 to 100 % on toggle On and from 100 to 0% on toggle Off.
Minimum brightness on toggle On: Brightness level (in percent) applied when there is a toggle On and current brightness is lower than 'Min brightness on toggle'. Default is 3%. Not applied when explicit (custom) transition is defined in Schedules and Actions.
Min/Max brightness: Reframes the range of the dimming signal to get more precise brightness control on the output.
Switch/Button input mode: Allows flexible input control through switches and/or buttons
- One button dimming control
- Dual button dimming control
Button fade rate: Controls how quickly the output brightness changes while holding the button(s). Default is 3x.
Button presets: State to be applied on double-push (double-click) event. Default value is 100%
Automatic dimming calibration: Provides smooth dimming throughout the entire range.
Virtual components: A special set of components that do not exist in the device initially and are created dynamically by the user.
KNX: Supports KNXnet/IP communication

Use cases

Retrofit your existing lighting system with the Dimmer Gen3 even if there is no neutral wire and continue using your current switches and electrical installation.
Control brightness of dimmable lights to set the perfect brightness.
Create smart schedules to have lights automatically adjust their brightness throughout the day.
Sync your lights with sunrise and sunset times easily using smart schedules.
Activate a night mode for reduced brightness during nighttime hours.
Integrate the Dimmer Gen3 with third-party systems like Home Assistant, Google Home, Alexa, and SmartThings for expanded control options.
Utilize the device to dim lights up or down with a single or double button press.
Enhance the safety by creating actions to have the lights automatically on when Shelly Motion detects movement.
