The openHAB bindings are still in beta, but the development was stopped.
This is the description of the openHAB API bindings for the Isolator Bricklet. General information and technical specifications for the Isolator Bricklet are summarized in its hardware description.
An installation guide for the openHAB API bindings is part of their general description.
Required firmware version:
Firmware update supported:
Channels: Actions: Parameters:
- SPITFP Dynamic Baudrate – Type: boolean, Default: true
- The SPITF protocol can be used with a dynamic baudrate. If the dynamic baudrate is enabled, the Brick will try to adapt the baudrate for the communication between Bricks and Bricklets according to the amount of data that is transferred. The baudrate for communication config between Brick and Isolator Bricklet can be set through the configuration of the Brick. The baudrate will be increased exponentially if lots of data is sent/received and decreased linearly if little data is sent/received. This lowers the baudrate in applications where little data is transferred (e.g. a weather station) and increases the robustness. If there is lots of data to transfer (e.g. Thermal Imaging Bricklet) it automatically increases the baudrate as needed. In cases where some data has to transferred as fast as possible every few seconds (e.g. RS485 Bricklet with a high baudrate but small payload) you may want to turn the dynamic baudrate off to get the highest possible performance. The maximum value of the baudrate can be set per port. If the dynamic baudrate is disabled, the maximum baudrate will be used statically.
- SPITFP Minimum Dynamic Baudrate – Type: integer, Default: 400000, Min: 400000, Max: 2000000
- See SPITFP Dynamic Baudrate
- SPITFP (Maximum) Baudrate – Type: integer, Default: 1400000, Min: 400000, Max: 2000000
- The baudrate used to communicate with the Bricklet. If you want to increase the throughput of Bricklets you can increase the baudrate. If you get a high error count because of high interference you can decrease the baudrate. If the dynamic baudrate feature is enabled, this is the maximum baudrate. Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.
- Statistics Update Interval – Type: integer, Default: 1000, Unit: ms, Min: 0, Max: 4294967295
- Specifies the update interval for all statistics data in milliseconds. A value of 0 disables automatic updates.
- 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
Messages From Brick¶
Count of messages passed through the Isolator from the controlling Brick.
Messages From Bricköet¶
Count of messages passed through the Isolator from the isolated Bricklet.
Device Name of the isolated Bricklet.
UID of the isolated Bricklet.
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:brickletisolator:[UID]") val hwVersion = actions.brickletIsolatorGetIdentity().get("hardwareVersion") as short logInfo("Example", "Hardware version: " + hwVersion.get(0) + "." + hwVersion.get(1) + "." + hwVersion.get(2))
Returns statistics for the Isolator Bricklet.
Returns the baudrate config, see the thing configuration.
Returns the error count for the communication between Isolator Bricklet and
the connected Bricklet. Call
GetSPITFPErrorCount() to get the
error count between Isolator Bricklet and Brick.
The errors are divided into
Returns the baudrate, see the thing configuration.
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.
Returns the configuration as set by the thing configuration
The following constants are available for this function:
Returns the error count for the communication between Brick and Bricklet.
The errors are divided into
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.
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!
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.
