Smarthomatic Binding

Smarthomatic Binding

Available from Version 1.9

The Smarthomatic binding will connect a network of Smarthomatic devices to the openhab server. Information's about Smarthomatic devices can be found here: Smarthomatic Project

Currently only incoming messages of the Smarthomatic env sensor are tested.

Configuration of openhab.cfg

smarthomatic:serialPort=/dev/ttyUSB0
smarthomatic:baud=19200

In the config file openhab.cfg there need to be line on which COM port the Smarthomatic Basestation is sending it's messages.

Item Configuration:

Item configuration basically looks like that:

itemtype itemname ["labeltext"] [<iconname>] [(group1, group2, ...)] [{bindingconfig}]

The format of the binding configuration looks like this:

smarthomatic="<direction>[<deviceId>, <messageGroupId>, <messageId>, <messagePart>:<transformationrule>]"

where <direction> is one of the following values:

• < - for inbound communication, whereby the openHAB runtime will listen for incoming messaged from the smarthomatic basestation

• • for outbound communication, whereby the openHAB runtime will send messages to the smarthomatic basestation

• = - for two way communication where the openhab will send and receive messages.

where <deviceId> is the senderId or the receiverId depending on the direction of the message.

where <messageGroupId> is the messageGroupId of the message

where <messageId> is the messageId of the message

where <messagePart> is the optional part that determines the part of a massageData part. For messages that contain multiple parts for example HumidityTemperature or messageData that contains arrays.

where <transformationrule> is the optional part if the message needs to be transformed. For example if we need a divion by 100. It uses the inbuild transformation services.

Example item definition:

Number luftfeuchtigkeit {smarthomatic="<[deviceId=10, messageGroupId=10, messageId=2, messagePart=0:JS(getDiv10.js)]"}
Number temperatur {smarthomatic="<[deviceId=10, messageGroupId=10, messageId=2, messagePart=1:JS(getDiv100.js)]"}
Number helligkeit {smarthomatic="<[deviceId=10, messageGroupId=11, messageId=1]"}`
Color dimmer {smarthomatic=">[deviceId=120, messageGroupId=60, messageId=10]"}
Number dimmer {smarthomatic="=[deviceId=140, messageGroupId=60, messageId=1]"}
Switch digitalSwitch {smarthomatic="<[deviceId=150, messageGroupId=1, messageId=1, messagePart=1]"}

Example transformation function:

(function(i) {
    return Number(i) / 10;
})(input)
