openHAB - Temperature IR Bricklet 2.0

Bemerkung

Die openHAB-Dokumentation ist nur auf Englisch verfügbar.

Warnung

The openHAB bindings are still in beta, but the development was stopped.

This is the description of the openHAB API bindings for the Temperature IR Bricklet 2.0. General information and technical specifications for the Temperature IR Bricklet 2.0 are summarized in its hardware description.

An installation guide for the openHAB API bindings is part of their general description.

Thing

UID:
  • tinkerforge:bricklettemperatureirv2:[UID]
Required firmware version:
  • 2.0.0
Firmware update supported:
  • yes
Channels:
Actions:
Parameters:
  • Status LED Configuration – Type: Choice, Default: Show Status
  • The status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets. You can also turn the LED permanently on/off or show a heartbeat. If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.
  • Options: Off, On, Show Heartbeat, Show Status

Channels

Ambient Temperature

The measured ambient temperature

Type:
  • Number:Temperature
UID:
  • tinkerforge:bricklettemperatureirv2:[UID]:BrickletTemperatureIRV2AmbientTemperature
Read only:
  • Yes
Unit:
  • Celsius
Range:
  • -40 Celsius to 125 Celsius (Step 0.1 Celsius)
Parameters:
  • Update Interval – Type: integer, Default: 1000, Unit: ms, Min: 0, Max: 4294967295
  • Specifies the update interval in milliseconds. A value of 0 disables automatic updates.
Object Temperature

The measured object temperature, i.e. the temperature of the surface of the object the sensor is aimed at. The temperature of different materials is dependent on their emissivity.

Type:
  • Number:Temperature
UID:
  • tinkerforge:bricklettemperatureirv2:[UID]:BrickletTemperatureIRV2ObjectTemperature
Read only:
  • Yes
Unit:
  • Celsius
Range:
  • -70 Celsius to 380 Celsius (Step 0.1 Celsius)
Parameters:
  • Update Interval – Type: integer, Default: 1000, Unit: ms, Min: 0, Max: 4294967295
  • Specifies the update interval in milliseconds. A value of 0 disables automatic updates.

Actions

Actions can be used in rules by creating an action object. All actions return a Map<String, Object>. Returned values can be accessed by name, sometimes the type deduction needs some hints, as shown below:

val actions = getActions("tinkerforge", "tinkerforge:bricklettemperatureirv2:[UID]")
val hwVersion = actions.brickletTemperatureIRV2GetIdentity().get("hardwareVersion") as short[]
logInfo("Example", "Hardware version: " + hwVersion.get(0) + "." + hwVersion.get(1) + "." + hwVersion.get(2))

Basic Actions

brickletTemperatureIRV2GetAmbientTemperature()
Return Map:
  • temperature – Type: int, Unit: 1/10 °C, Range: [-400 to 1250]

Returns the ambient temperature of the sensor.

If you want to get the value periodically, it is recommended to use the Ambient Temperature channel. You can set the channel configuration with the configuration of Ambient Temperature.

brickletTemperatureIRV2GetObjectTemperature()
Return Map:
  • temperature – Type: int, Unit: 1/10 °C, Range: [-700 to 3800]

Returns the object temperature of the sensor, i.e. the temperature of the surface of the object the sensor is aimed at.

The temperature of different materials is dependent on their emissivity. The emissivity of the material can be set with This function is not available in openHAB. Please use Brick Viewer to change persistant device settings.

If you want to get the value periodically, it is recommended to use the Object Temperature channel. You can set the channel configuration with the configuration of Object Temperature.

Advanced Actions

brickletTemperatureIRV2GetEmissivity()
Return Map:
  • emissivity – Type: int, Unit: 1/65535, Range: [6553 to 216 - 1], Default: 216 - 1

Returns the emissivity as set by This function is not available in openHAB. Please use Brick Viewer to change persistant device settings.

brickletTemperatureIRV2GetChipTemperature()
Return Map:
  • temperature – Type: int, Unit: 1 °C, Range: [-215 to 215 - 1]

Returns the temperature as measured inside the microcontroller. The value returned is not the ambient temperature!

The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.

brickletTemperatureIRV2GetStatusLEDConfig()
Return Map:
  • config – Type: int, Range: See constants, Default: 3

Returns the configuration as set by the thing configuration

The following constants are available for this function:

For config:

  • val STATUS_LED_CONFIG_OFF = 0
  • val STATUS_LED_CONFIG_ON = 1
  • val STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
  • val STATUS_LED_CONFIG_SHOW_STATUS = 3
brickletTemperatureIRV2GetSPITFPErrorCount()
Return Map:
  • errorCountAckChecksum – Type: long, Range: [0 to 232 - 1]
  • errorCountMessageChecksum – Type: long, Range: [0 to 232 - 1]
  • errorCountFrame – Type: long, Range: [0 to 232 - 1]
  • errorCountOverflow – Type: long, Range: [0 to 232 - 1]

Returns the error count for the communication between Brick and Bricklet.

The errors are divided into

  • ACK checksum errors,
  • message checksum errors,
  • framing errors and
  • overflow errors.

The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.

brickletTemperatureIRV2Reset()

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

brickletTemperatureIRV2GetIdentity()
Return Map:
  • uid – Type: String, Length: up to 8
  • connectedUid – Type: String, Length: up to 8
  • position – Type: char, Range: ['a' to 'h', 'z']
  • hardwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • firmwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • deviceIdentifier – Type: int, Range: [0 to 216 - 1]

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here. 

Internal Actions

brickletTemperatureIRV2ReadUID()
Return Map:
  • uid – Type: long, Range: [0 to 232 - 1]

Returns the current UID as an integer. Encode as Base58 to get the usual string version.
