# Sbus Binding

This binding integrates Sbus devices with openHAB, allowing control and monitoring of Sbus-compatible devices over UDP. Sbus is a protocol used for home automation devices that communicate over UDP networks. The binding supports various device types including RGB/RGBW controllers, temperature sensors, and switch controllers.

# Supported Things

  • udp - Sbus Bridge for UDP communication
  • rgbw - RGB/RGBW Controllers for color and brightness control
  • temperature - Temperature Sensors for monitoring environmental conditions
  • switch - Switch Controllers for basic on/off and dimming control

# Discovery

Sbus devices communicate via UDP broadcast, but manual configuration is required to set up the devices in openHAB. Auto-discovery is not supported at this moment.

# Binding Configuration

The binding itself does not require any special configuration.

# Thing Configuration

# Bridge Configuration

The Sbus Bridge has the following configuration parameters:

Name Type Description Default Required Advanced
host text IP address of the Sbus device (typically broadcast) N/A yes no
port integer UDP port number 6000 no no

# RGBW Controller Configuration

Name Type Description Default Required Advanced
subnetId integer Subnet ID the RGBW controller is part of N/A yes no
id integer Device ID of the RGBW controller N/A yes no
refresh integer Refresh interval in seconds 30 no yes

# Temperature Sensor Configuration

Name Type Description Default Required Advanced
subnetId integer Subnet ID the temperature sensor is part of N/A yes no
id integer Device ID of the temperature sensor N/A yes no
refresh integer Refresh interval in seconds 30 no yes

# Switch Controller Configuration

Name Type Description Default Required Advanced
subnetId integer Subnet ID the switch controller is part of N/A yes no
id integer Device ID of the switch controller N/A yes no
refresh integer Refresh interval in seconds 30 no yes

# Channels

# RGBW Controller Channels

Channel Type Read/Write Description
color Color RW HSB color picker that controls RGBW components (0-100%)
switch Switch RW On/Off control for the RGBW output with optional timer

# Temperature Sensor Channels

Channel Type Read/Write Description
temperature Number:Temperature R Current temperature reading. Can be configured to use Celsius (default) or Fahrenheit units

# Switch Controller Channels

Channel Type Read/Write Description
switch Switch RW Basic ON/OFF state control
dimmer Dimmer RW ON/OFF state with timer transition
paired Contact RW OPEN/CLOSED state for two paired channels (e.g., curtains)

# Thing Configuration

Bridge sbus:udp:mybridge [ host="192.168.1.255", port=5000 ] {
    Thing rgbw colorctrl [ id=72, refresh=30 ] {
        Channels:
            Type color-channel : color [ channelNumber=1 ]   // HSB color picker, RGBW values stored at channel 1
            Type switch-channel : power [ channelNumber=1 ]  // On/Off control for the RGBW output For complex scenes, one Sbus color controller can keep up to 40 color states. The switch channelNumber has to fall into this range.
    }
    
    Thing temperature temp1 [ id=62, refresh=30 ] {
        Channels:
            Type temperature-channel : temperature [ channelNumber=1 ]
