# Velbus Binding
The Velbus binding integrates with a Velbus (opens new window) system through a Velbus configuration module (VMBRSUSB, VMB1USB or VMB1RS) or a network connection (TCP/IP).
The binding has been tested with a USB configuration module for universal mounting (VMB1USB). For optimal stability, the preferred configuration module is the VMBRSUSB module.
The binding exposes basic actions from the Velbus System that can be triggered from the smartphone/tablet interface, as defined by the Velbus Protocol info sheets (opens new window).
Supported item types are switches, dimmers and rollershutters. Pushbutton, temperature sensors and input module states are retrieved and made available in the binding.
# Supported Things
A Velbus configuration module (e.g. VMBRSUSB) or a network server (e.g. VelServer (opens new window)) is required as a "bridge" for accessing any other Velbus devices.
The supported Velbus devices are:
vmb1bl, vmb1bls, vmb1dm, vmb1led, vmb1ry, vmb1ryno, vmb1rynos, vmb1rys, vmb1ts, vmb2bl, vmb2ble, vmb2pbn, vmb4an, vmb4dc, vmb4ry, vmb4ryld, vmb4ryno, vmb6in, vmb6pbn, vmb7in, vmb8ir, vmb8pb, vmb8pbu, vmbdme, vmbdmi, vmbdmir, vmbel1, vmbel2, vmbel4, vmbelo, vmbelpir, vmbgp1, vmbgp2, vmbgp4, vmbgp4pir, vmbgpo, vmbgpod, vmbmeteo, vmbpirc, vmbpirm, vmbpiro, vmbvp1
The type of a specific device can be found in the configuration section for things in the UI. It is part of the unique thing id which could look like:
velbus:vmb4ryld:0424e5d2:01:CH1
The thing type is the second string behind the first colon and in this example it is vmb4ryld.
# Discovery
The Velbus bridge cannot be discovered automatically. It has to be added manually by defining the serial port of the Velbus Configuration module for the Velbus Serial Bridge or by defining the IP Address and port for the Velbus Network Bridge.
Once the bridge has been added as a thing, a manual scan can be launched to discover all other supported Velbus devices on the bus. These devices will be available in the inbox. The discovery scan will also retrieve the channel names of the Velbus devices.
# Thing Configuration
The Velbus bridge needs to be added first.
For the Velbus Serial Bridge it is necessary to specify the serial port device used for communication.
On Linux systems, this will usually be either /dev/ttyS0
, /dev/ttyUSB0
or /dev/ttyACM0
(or a higher number than 0
if multiple devices are present).
On Windows it will be COM1
, COM2
, etc.
In the things file, this might look e.g. like
Bridge velbus:bridge:1 [ port="COM1" ]
For the Velbus Network Bridge it is necessary to specify the IP Address or hostname and the port of the Velbus network server.
This will usually be either the loopback address 127.0.0.1
, and port number.
Or the specific IP of the machine 10.0.0.110
, and port number.
In the things file, this might look like
Bridge velbus:networkbridge:1 "Velbus Network Bridge - Loopback" @ "Control" [ address="127.0.0.1", port=6000 ]
Optionally, both the serial bridge and the network bridge can also update the realtime clock, date and daylight savings status of the Velbus modules. This is achieved by setting the Time Update Interval (in minutes) on the bridge, e.g.:
Bridge velbus:bridge:1 [ port="COM1", timeUpdateInterval="360" ]
The default time update interval is every 360 minutes. Setting the interval to 0 minutes or leaving it empty disables the update of the realtime clock, date and daylight savings status of the Velbus modules.
In case of a connection error, the bridges can also try to reconnect automatically. You can specify at which interval the bridge should try to reconnect by setting the Reconnection Interval (in seconds), e.g.:
Bridge velbus:bridge:1 [ port="COM1", reconnectionInterval="15" ]
The default reconnection interval is 15 seconds.
For the other Velbus devices, the thing configuration has the following syntax:
Thing velbus:<thing type>:<bridgeId>:<thingId> "Label" @ "Location" [CH1="Kitchen Light", CH2="Living Light"]
or nested in the bridge configuration:
<thing type> <thingId> "Label" @ "Location" [CH1="Kitchen Light", CH2="Living Light"]
The following thing types are valid for configuration:
vmb1bl, vmb1bls, vmb1dm, vmb1led, vmb1ry, vmb1ryno, vmb1rynos, vmb1rys, vmb1ts, vmb2bl, vmb2ble, vmb2pbn, vmb4an, vmb4dc, vmb4ry, vmb4ryld, vmb4ryno, vmb6in, vmb6pbn, vmb7in, vmb8ir, vmb8pb, vmb8pbu, vmbdme, vmbdmi, vmbdmir, vmbel1, vmbel2, vmbel4, vmbelo, vmbelpir, vmbgp1, vmbgp2, vmbgp4, vmbgp4pir, vmbgpo, vmbgpod, vmbmeteo, vmbpirc, vmbpirm, vmbpiro, vmbvp1
thingId
is the hexadecimal Velbus address of the thing.
"Label"
is an optional label for the thing.
@ "Location"
is optional, and represents the location of the thing.
[CHx="..."]
is optional, and represents the name of channel x, e.g. CH1 specifies the name of channel 1.
For thing types with builtin sensors (e.g. temperature), the interval at which the sensors should be checked can be set by specifying the Refresh Interval, e.g.:
Thing velbus:vmbelo:<bridgeId>:<thingId> [refresh="300"]
The default refresh interval for the sensors is 300 seconds. Setting the refresh interval to 0 or leaving it empty will prevent the thing from periodically refreshing the sensor values.
The following thing types support a sensor refresh interval:
vmb1ts, vmb4an, vmbel1, vmbel2, vmbel4, vmbelo, vmbelpir, vmbgp1, vmbgp2, vmbgp4, vmbgp4pir, vmbgpo, vmbgpod, vmbmeteo, vmbpirc, vmbpirm, vmbpiro
The vmb7in
thing type also supports a refresh interval. For this thing type, the refresh interval is the interval at which the counter values should be refreshed.
For dimmers the speed (in seconds) at which the modules should dim from 0% to 100% can be set by specifying the Dimspeed, e.g.:
Thing velbus:vmb4dc:<bridgeId>:<thingId> [dimspeed="5"]
The following thing types support setting the dimspeed:
vmb1dm, vmb1led, vmb4dc, vmbdme, vmbdmi, vmbdmir
