Die openHAB-Dokumentation ist nur auf Englisch verfügbar.
The openHAB bindings are still in beta, but the development was stopped.
This is the description of the openHAB API bindings for the Rotary Encoder Bricklet 2.0. General information and technical specifications for the Rotary Encoder Bricklet 2.0 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:
- 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
The current count of the encoder. The encoder has 24 steps per rotation. Turning the encoder to the left decrements the counter, so a negative count is possible.
- 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.
Resets the counter to 0.
- Commands (String)
- Accepts any string
Triggers if the button is pressed or released
- Trigger (system.rawbutton)
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:brickletrotaryencoderv2:[UID]") val hwVersion = actions.brickletRotaryEncoderV2GetIdentity().get("hardwareVersion") as short logInfo("Example", "Hardware version: " + hwVersion.get(0) + "." + hwVersion.get(1) + "." + hwVersion.get(2))
Returns the current count of the encoder. If you set reset to true, the count is set back to 0 directly after the current count is read.
The encoder has 24 steps per rotation.
Turning the encoder to the left decrements the counter, so a negative count is possible.
If you want to get the value periodically, it is recommended to use the
Count channel. You can set the channel configuration
with the configuration of
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.
