Description
Main features
DIN rail mountable
Automatic dimming calibration: Provides smooth dimming throughout the entire range.
Switch/Button input mode: Allows flexible input control through switches or buttons.
One/dual button dimming control: Allows to use the full functionalities of the Device for dimming control with any wall switch configuration.
Night mode: Enables to set a specific brightness of input lights during nighttime.
Min/Max brightness: Reframes the range of the dimming signal to get more precise brightness control on the output.
Button fade rate: Controls how quickly the output brightness changes while holding the button(s).
Transition duration: Controls the time for dimming from 0 to 100 %.
Warm-up: Set brightness and time that will create an initial impulse for light bulbs that need more energy to wake up when the brightness is below 10%.
Gamma correction: adjusts the control signal so that each step in dimming appears evenly spaced in brightness to prevent lights from seeming too jumpy at low levels or too compressed at high levels. Range: 0.4 – 4.0. Default value (no correction): 1.0
Safety: Оver current/voltage/power protections
Weekly schedules: Supports daily schedules and routines, 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: 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.
No need for hub: Ready for use locally or remotely via Shelly Smart Control or 3rd Party systems.
