Niko Home Control Binding

The Niko Home Control binding integrates with a Niko Home Control system through a Niko Home Control IP-interface.

The binding has been tested with a Niko Home Control IP-interface (550-00508). This IP-interface provides access on the LAN. The binding does not require a Niko Home Control Gateway (550-00580), but does work with it in the LAN. It will not make a remote connection. It has also been confirmed to work with the Niko Home Control Connected Controller (550-00003).

The binding exposes all actions from the Niko Home Control System that can be triggered from the smartphone/tablet interface, as defined in the Niko Home Control programming software.

Supported actions are types are switches, dimmers and rollershutters. Niko Home Control alarm and notice messages are retrieved and made available in the binding.

Supported Things

The Niko Home Control Controller is represented as a bridge in the binding. Connected to a bridge, the Niko Home Control Binding supports on/off actions (e.g. for lights or groups of lights), dimmers and rollershutters or blinds.

Binding Configuration

The bridge representing the Niko Home Control IP-interface needs to be added first in the things file or through Paper UI. A bridge can be auto-discovered or created manually. No bridge configuration is required when using auto-discovery.

The IP-address and port can be set when manually creating the bridge.

If the IP-address is set, no attempt will be made to discover the correct IP-address. You are responsible to force a fixed IP address on the Niko Home Control IP-interface through settings in your DHCP server.

The port is set to 8000 by default and should match the port used by the Niko Home Control IP-interface.

An optional refresh interval will be used to restart the bridge at regular intervals (every 300 minutes by default). Restarting the bridge at regular times improves the connection stability and avoids loss of connection. It can be turned off completely.

Discovery

A discovery scan will first discover the Niko Home Control IP-interface in the network as a bridge. Default parameters will be used. Note that this may fail to find the correct Niko Home Control IP-interface when there are multiple IP-interfaces in the network.

When the Niko Home Control bridge is added as a thing, from the discovery inbox or manually, system information will be read from the Niko Home Control Controller and will be put in the bridge properties, visible through Paper UI.

Subsequently, all defined actions that can be triggered from a smartphone/tablet in the Niko Home Control system will be discovered and put in the inbox. It is possible to trigger a manual scan for things on the Niko Home Control bridge.

If the Niko Home Control system has locations configured, these will be copied to thing locations and grouped as such in PaperUI. Locations can subsequently be changed through the thing location paramter in PaperUI.

Thing Configuration

Besides using PaperUI to manually configure things or adding automatically discovered things through PaperUI, you can add thing definitions in the things file.

The Thing configuration for the bridge uses the following syntax:

Bridge nikohomecontrol:bridge:<bridgeId> [ addr="<IP-address of IP-interface>", port=<listening port>,
                                           refresh="<Refresh interval>" ]

bridgeId can have any value.

addr is the fixed Niko Home Control IP-interface address and is required. port will be the port used to connect and is 8000 by default. refresh is the interval to restart the communication in minutes (300 by default), if 0 or omitted the connection will not restart at regular intervals.

The thing configuration for the actions has the following syntax:

Thing nikohomecontrol:<thing type>:<bridgeId>:<thingId> "Label" @ "Location"
                        [ actionId=<Niko Home Control action ID>,
                          step=<dimmer increase/decrease step value> ]

or nested in the bridge configuration:

<thing type> <thingId> "Label" @ "Location" [ actionId=<Niko Home Control action ID>,
                         step=<dimmer increase/decrease step value> ]

The following thing types are valid for configuration:

onOff, dimmer, blind

thingId can have any value, but will be set to the same value as the actionId parameter if discovery is used.

"Label" is een optional label for the thing.

@ "Location" is optional, and represents the location of the thing. Auto-discovery would have assigned a value automatically.

The actionId parameter is the unique ip Interface Object ID (ipInterfaceObjectId) as automatically assigned in the Niko Home Control Controller when programming the Niko Home Control system using the Niko Home Control programming software. It is not directly visible in the Niko Home Control programming or user software, but will be detected and automatically set by openHAB discovery. For textual configuration, you can be manually retrieve it from the content of the .nhcp configuration file created by the programming software. Open the file with an unzip tool to read it’s content.

The step parameter is only available for dimmers. It sets a step value for dimmer increase/decrease actions. The parameter is optional and set to 10 by default.

Channels

For thing type onOff the supported channel is switch. OnOff command types are supported.

For thing type dimmer the supported channel is brightness. OnOff, IncreaseDecrease and Percent command types are supported. Note that sending an ON command will switch the dimmer to the value stored when last turning the dimmer off, or 100% depending on the configuration in the Niko Home Control Controller. This can be changed with the Niko Home Control programming software.

For thing type blind the supported channel is rollershutter. UpDown, StopMove and Percent command types are supported.

The bridge has two trigger channels alarm and notice. It can be used as a trigger to rules. The event message is the alarm or notice text coming from Niko Home Control.

Limitations

The binding has been tested with a Niko Home Control IP-interface (550-00508) and the Niko Home Control Connected Controller (550-00003).

The action events implemented are limited to onOff, dimmer and rollershutter or blinds. Other actions have not been implemented.

It is not possible to tilt the slats of venetian blinds.

Beyond action events, the Niko Home Control communication also supports thermostats, electricity usage data and alarms. This has not been implemented.

Example

.things:

Bridge nikohomecontrol:bridge:nhc1 [ addr="192.168.0.70", port=8000, refresh=300 ] {
    onOff 1 "LivingRoom" @ "Downstairs" [ actionId=1 ]
    dimmer 2 "TVRoom" [ actionId=2, step=5 ]
    blind 3 [ actionId=3 ]
}

Bridge nikohomecontrol:bridge:nhc2 [ addr="192.168.0.110" ] {
    onOff 11 @ "Upstairs"[ actionId=11 ]
    dimmer 12 [ actionId=12, step=5 ]
    blind 13 [ actionId=13 ]
}

.items:

Switch LivingRoom       {channel="nikohomecontrol:onOff:nhc1:1:switch"}          # Switch for onOff type action
Dimmer TVRoom           {channel="nikohomecontrol:dimmer:nhc1:2:brightness"}     # Changing brightness dimmer type action
Rollershutter Kitchen   {channel="nikohomecontrol:blind:nhc1:3:rollershutter"}   # Controlling rollershutter or blind type action

.sitemap:

Switch item=LivingRoom
Slider item=TVRoom
Switch item=TVRoom          # allows switching dimmer item off or on (with controller defined behavior)
Rollershutter item=Kitchen

Example trigger rule:

rule "example trigger rule"
when
    Channel 'nikohomecontrol:bridge:nhc1:alarm' triggered or
    Channel 'nikohomecontrol:bridge:nhc1:notice' triggered
then
    var message = receivedEvent.getEvent()
    logInfo("nhcTriggerExample", "Message: {}", message)
    ...
