Documentation of the TinkerForge binding bundle

Introduction

TinkerForge is a system of open source hardware building blocks that allows you to combine sensor and actuator blocks by plug and play. You can create your individual hardware system by choosing the necessary building blocks for your project and combine it with other home automation products. There are many blocks available e.g for temperature, humidity or air pressure measurement as well as for I/O, LCDs and motor control. You will find a complete List of available blocks here.

This binding connects the TinkerForge devices to the openHAB event bus. Sensor values from devices are made available to openHAB and actions on devices can be triggered by openHAB.

For now only a subset of the TinkerForge devices and features are supported, but more devices and features will be added in the near future.

The following devices are supported for now:

Servo Brick
DC Brick
Dual Relay Bricklet
Humidity Bricklet
Distance IR Bricklet
Temperature Bricklet
Barometer Bricklet (barometer and temperature device)
Ambient Light Bricklet
LCD 20×4 Bricklet (LCD, backlight and 4 buttons)
Industrial Quad Relay
Bricklet Industrial Digital In 4
Bricklet IO-16
Bricklet Remote Switch
Bricklet Motion Detector
Bricklet MultiTouch
Bricklet TemperatureIR
Bricklet SoundIntensity
Bricklet Moisture
Bricklet DistanceUS
Bricklet VoltageCurrent
Bricklet Tilt
Bricklet IO-4
Bricklet Industrial Digital Out 4
Bricklet Segment Display 4x7
Bricklet LED Strip

The TinkerForge binding bundle is available as a separate (optional) download. For installation of the binding, please see Wiki page Bindings.

Upgrading from 1.3

LCDBacklight now is a sub device of LCD20x4 Bricklet (items file has to be changed)
LCD20x4Button now posts an update not a command anymore (rules has to be changed)
IndustrialQuadRelay sub id numbering now starts from zero (items file has to be changed)

Upgrading from 1.4

Threshold values now have the same unit as the sensor value (incompatible change, you may have to update your openhab.cfg).
- Background: Some getters for sensor values of the TinkerForge API return higher precision values by using short values with fractions of the common units, e.g. the Temperature Bricklet returns hundredths of a celsius degree. The binding converts these values to common units using a BigDecimal. Until now the threshold values were applied to the sensor value before this conversion. Because of that the threshold values had to be given as the appropriate fraction. With the drawback that the openHAB users need some knowledge about the behavior of the TinkerForge API. Now the threshold is applied after converting the original values. Therefore the units used for the sensor values and the threshold values are equal.
- Humidity Bricklet
  - calculate new threshold values from values of your current configuration: divide by 10
  - unity: relative humidity in percent
- Distance IR Bricklet
  - calculate new threshold values from values of your current configuration: nothing changed
  - unity: millimeter
- Temperature Bricklet
  - calculate new threshold values from values of your current configuration: divide by 100
  - unity: degree Celsius
- Barometer Bricklet
  - calculate new threshold values from values of your current configuration: divide by 1000
  - unity: mbar
- Ambient Light Bricklet
  - calculate new threshold values from values of your current configuration: divide 10
  - unity: Lux

General Remarks

The binding supports the connection to several brickd instances.

The binding supports the TinkerForge auto reconnect feature. Furthermore even if the initial connect failed the binding will make retries to get connected to the brickd.

Generic Item Binding Configuration

Basic Configuration

In order to connect openHAB to TinkerForge devices you need to define all the brickd hosts and ports in the openhab.cfg file.

The following properties must be configured to define a brickd connection:

tinkerforge:hosts="<IP address>[:port] ..."

The properties indicated by '<...>' need to be replaced with an actual value. Properties surrounded by square brackets are optional.

Property	Description
IP address	IP address of the brickd
port	The listening port of of the brickd (optional, default 4223)

For connecting several brickds, use multiple <IP address> statements delimited by a space.

Devices which do not support callbacks will be polled with a configurable interval, the default is 60000 milliseconds. This value can be changed in openhab.cfg:

tinkerforge.refresh=<value in milliseconds>

Example Configurations

Example for a connection to a single brickd:

tinkerforge:hosts=127.0.0.1

Example for several brickd connections using different ports:

tinkerforge:hosts=127.0.0.1:4224 192.168.1.50 192.168.1.104

Advanced Configuration

There are several configuration parameters to control the behavior of the devices. The available parameters depend on the device type.

Overview

For most of the devices no configuration is needed in openhab.cfg, they can be used with reasonable defaults. The only exception is the IO16 Bricklet (see below).

If you want to get rid of uid and subid statements in the items or rule file, you can use openhab.cfg to get a symbolic name.

A configuration line for a TinkerForge Device looks like this in openhab.cfg:

tinkerforge:<symbolic name>.<property>=<value>

The symbolic name string can be used in the items configuration as an alternative for the uid and subid values.

The following table lists the general available properties.

Property	Description	Device
uid	TinkerForge uid of the device (use the Brick Viewer to get this value)	mandatory for all devices
type	the device type	mandatory for all devices
subid	subid of the device, subid's are used if a brick/bricklet houses more then one device (e.g. the Dual Relay Bricklet)	mandatory for sub devices

The following table shows the TinkerForge device, its device type, subid and if it is an actuator.

Callback and Threshold

The TinkerForge CallbackListeners - if available - are used to observe the sensor values of the devices. These listeners are configured to update sensor values at a given time period (callbackPeriod). The default configuration sets the callbackPeriod to 1 second. This value can be changed in openhab.cfg. For now this value must be changed for every single device. The values must be given in milliseconds.

The callbackPeriod controls the amount of traffic from the TF hardware to the binding.

In addition to the Callback a threshold value can be configured. This threshold means that even if the listener reports a changed value, the value is only send to the openHAB eventbus if: the difference between the last value and the current value is bigger than the threshold value. You can think of it as a kind of hysteresis, it dampens the oscillation of openHAB item values.

The threshold controls the amount of traffic from the binding to the openHAB eventbus.

Text item=SoundIntensity

Tilt Bricklet

You can use a contact, number or switch item.

An entry in openhab.cfg is only needed if you want to use a symbolic name.

bricklet:

property	descripition	values
uid	tinkerforge uid	get value from brickv
type	openHAB type name	bricklet_tilt

openhab.cfg:

tinkerforge:tilt.uid=j7k
tinkerforge:tilt.type=bricklet_tilt

items file entry (e.g. tinkerforge.items):

Segment Display 4x7

The LCD20x4 is a bit special as it acts as actuator which can receive number messages. To achieve this, you have to configure the device as Number item.

An entry in openhab.cfg is only needed if you want to use a symbolic name.

items file entry (e.g. tinkerforge.items):

Number Segment7         "Segment7" { tinkerforge="uid=kQg"}

rules file (e.g. tinkerforge.rules):

If you want to display the object temperature from a temperatureIr Item called ObjectTemperature this rule would do the trick for you.

rule "Weatherstation Segment update ObjectTemperature"
        when 
                Item ObjectTemperature received update
        then
                sendCommand(Segment7, ObjectTemperature.state))
end

LCD20x4 Bricklet

The LCD20x4 is a bit special as it acts as actuator which can receive text messages. To achieve this, you have to configure the device as String item.

What’s the meaning of this magic string?

sendCommand(TF_LCD, String::format("TFNUM<213>%4s"Barometer.state.format("%d")
                  ))

TFNUM is just a flag to signal the binding that some position information is passed. The first number is the line number, starting from 0. The second and third number are interpreted as the position in the line, starting from 0.

The above example would write the current value of the barometer bricklet to line 3 starting from position 14, with a fixed width of 4 (this is because of %4s).

Item Binding Configuration

In order to bind an item to a device, you need to provide configuration settings. The easiest way to do so is to add binding information in your item file (in the folder '${openhab_home}/configurations/items').

The configuration of the TinkerForge binding item looks like this:

tinkerforge="(uid=<id> [, subid=<id>] | name=<name>)"

The configuration is quite simple. You either have to set a value for the uid and optionally for the subid of the device, or - if the device is configured in openhab.cfg - the "symbolic name" of the device.

Property	Description
uid	TinkerForge uid of the device (Use the Brick Viewer to get this value)
subid	optional subid of the device
name	symbolic name of the device. The name is only available if there is some configuration for the device in openhab.cfg.

Item Types

Supported item types are "Switch Item", "Number Item", "Contact Item" and "String Item".
