Changelog

Unreleased changes

Internals

• Telegram: group_address renamed to destination_address, to prepare support for other APCI services.

0.15.6 Bugfix for StateUpater 2020-11-26

Bugfixes

• StateUpdater: shield from cancellation so update_received() don't cancel ongoing RemoteValue.read_state()

0.15.5 A Telegram for everyone 2020-11-25

Internals

• process every incoming Telegram in all Devices, regardless if a callback for the GA is registered (eg. StateUpdater) or not.

Bugfixes

• StateUpdater: always close the update task before starting a new in StateTracker
• Cover: separate target and state position RemoteValue to fix position update from RemoteValue and call after_update()

0.15.4 Bugfix for switch 2020-11-22

Devices

• Light, Switch: initialize state with None instead of False to account for unknown state.
• Cover: device_class may be used to store the type of cover for Home-Assistant.
• HA-Entity Light, Switch, Cover: initialize with assumed_state = True until we have received a state.

Bugfixes

• Switch.after_update was not called from RemoteValueSwitch.read_state (StateUpdater). Moved Switch.state to RemoteValue again.
• StateUpdater: query less aggressive - 2 parallel reads with 2 seconds timeout (instead of 3 - 1).

0.15.3 Opposite day! 2020-10-29

Devices

• BinarySensor: added option to invert payloads
• BinarySensor: ignore_internal_state and counter are only applied to GroupValueWrite telegrams, not GroupValueRespond.
• BinarySensor: if context_timeout is set ignore_internal_state is set to True.
• Switch: added option to invert payloads

Bugfixes

• HA Switch entity: keep state without state_address
• Cover: fix set_position without writable position / auto_stop_if_necessary
• handle unsupported CEMI Messages without loosing tunnel connection

0.15.2 Winter is coming

Devices

• ClimateMode: Refactor climate modes in operation_mode and controller_mode, also fixes a bug for binary operation modes where the mode would be set to AWAY no matter what value was sent to the bus.
• Sensor: Add always_callback option
• Switch: Allow resetting switches after x seconds with the new reset_after option.

Internals

• StateUpdater: Only request 3 GAs at a time.
• RemoteValue: Add support for passive group addresses

0.15.1 bugfix for binary sensors

Devices

• BinarySensor: reset_after expects seconds, instead of ms now (to use same unit as context_timeout)
• Binary Sensor: Change the default setting context_timeout for binary sensor from 1.0 to 0.0 and fixes a bug that would result in the update callback being executed twice thus executing certain automations in HA twice for binary sensor from 1.0 to 0.0 and fixes a bug that would result in the update callback being executed twice thus executing certain automations in HA twice.

0.15.0 Spring cleaning and quality of life changes

Logging

• An additional log_directory parameter has been introduced that allows you to log your KNX logs to a dedicated file. We will likely silence more logs over the time but this option will help you and us to triage issues easier in the future. It is disabled by default.

Internals

• The heartbeat task, that is used to monitor the state of the tunnel and trigger reconnects if it doesn't respond, is now properly stopped once we receive the first reconnect request
• XKNX.start() no longer takes arguments. They are now passed directly to the constructor when instantiating XKNX()
• Support for python 3.6 has been dropped
• XKNX can now be used as an asynchronous context manager
• Internal refactorings
• Improve test coverage

0.14.4 Bugfix release

Devices

• Don't set standby operation mode if telegram was not processed by any RemoteValue
• Allow covers to be inverted again
• Correctly process outgoing telegrams in our own devices

0.14.3 Bugfix release

Internals

• Make connectivity less noisy on connection errors.

0.14.2 Bugfix release

Bugfixes

• Correctly reset the counter of the binary sensor after a trigger.

0.14.1 Bugfix release

Bugfixes

• Use correct DPT 9.006 for the air pressure attribute of weather devices
• Reset binary sensor counters after the context has been timed out in order to be able to use state change events within HA
• Code cleanups

0.14.0 New sensor types and refacoring of binary sensor automations

Breaking changes

• Binary sensor automations within the home assistant integration have been refactored to use the HA built in events as automation source instead of having the automation schema directly attached to the sensors. (Migration Guide: https://xknx.io/migration_ha_0116.html)

New Features

• Add support for new sensor types DPT 12.1200 (DPT_VolumeLiquid_Litre) and DPT 12.1201 (DPTVolumeM3).
• Weather devices now have an additional brightness_north GA to measure the brightness. Additionally, all sensor values are now part of the HA device state attributes for a given weather device.

Bugfixes

• Fix hourly broadcasting of localtime

Internals

• Allow to pass GroupAddress and PhysicalAddress objects to wherever an address is acceptable.
• Stop heartbeat and reconnect tasks before disconnecting

0.13.0 New weather device and bugfixes for HA integration

Deprecation notes

• Python 3.5 is no longer supported

New Features

• Adds support for a weather station via a dedicated weather device
• support for configuring the previously hard-coded multicast address (@jochembroekhoff #312)

Internals

• GatewayScanner: Passing None or an integer <= 0 to the stop_on_found parameter now causes the scanner to only stop once the timeout is reached (@jochembroekhoff #311)
• Devices are now added automatically to the xknx.devices list after initialization
• Device.sync() method now again has a wait_for_result parameter that allows the user to wait for the telegrams
• The default timeout of the ValueReader has been extended from 1 second to 2 seconds

Bugfixes

• Device: Fixes a bug (#339) introduced in 0.12.0 so that it is again possible to have multiple devices with the same name in the HA integration

0.12.0 New StateUpdater, improvements to the HA integrations and bug fixes 2020-08-14

Breaking changes

• Climate: setpoint_shift_step renamed for temperature_step. This attribute can be applied to all temperature modes. Default is 0.1
• Removed significant_bit attribute in BinarySensor
• DateTime devices are initialized with sting for broadcast_type: "time", "date" or "datetime" instead of an Enum value
• Removed bind_to_multicast option in ConnectionConfig and UDPClient

New Features

• Cover: add optional group_address_stop for manual stopping
• Cover: start travel calculator when up/down telegram from bus is received
• HA integration: knx.send service takes type attribute to allow sending DPT encoded values like sensor
• HA integration: sensor and expose accept int and float values for type (parsed as DPT numbers)
• new StateUpdater: Devices sync_state can be set to init to just initialize state on startup, expire [minutes] to read the state from the KNX bus when it was not updated for [minutes] or every [minutes] to update it regularly every [minutes]
• Sensor and ExposeSensor now also accepts value_type of int (generic DPT) or float (specific DPT) if implemented.
• Added config option ignore_internal_state in binary sensors (@andreasnanko #267)
• Add support for 2byte float type (DPT 9.002) to climate shiftpoint

• ClimateMode: add group_address_heat_cool and `group_address_heat_cool_state for switching heating mode / cooling mode with DPT1

Bugfixes

• Tunneling: don't process incoming L_Data.con confirmation frames. This avoids processing every outgoing telegram twice.
• enable multicast on macOS and fix a bug where unknown cemi frames raise a TypeError on routing connections
• BinarySensor: reset_after is now implemented as asyncio.Task to prevent blocking the loop
• ClimateMode: binary climate modes should be fully functional now (sending, receiving and syncing)
• Cover: position update from bus does update current position, but not target position (when moving)

Internals

• Cover travelcalculator doesn't start from 0% but is initialized by first movement or status telegram
• Cover uses 0% for open cover and 100% for closed cover now
• DPT classes can now be searched via value_type string or dpt number from any parent class (DPTBase for all) to be used in Sensor
• Use RemoteValue class in BinarySensor, DateTime and ClimateMode device
• use time.struct_time for internal time and date representation
• use a regular Bool type for BinarySensor state representation
• RemoteValue.process has always_callback attribute to run the callbacks on every process even if the payload didn't change

0.7.0 - Released 2017-07-30

More asyncio:

More intense usage of asyncio. All device operations and callback functions are now async.

E.g. to switch on a light you have to do:

await light.set_on()

See updated examples for details.

Renaming of several objects:

The naming of some device were changed in order to get the nomenclature closer to several other automation projects and to avoid confusion. The device objects were also moved into xknx.devices.

Climate

Renamed class Thermostat to Climate . Plase rename the section within configuration:

groups:
  climate:
    Cellar.Thermostat: { group_address_temperature: "6/2/0" }

Cover

Renamed class Shutter to Cover. Plase rename the section within configuration:

groups:
  cover:
    Livingroom.Shutter_1:
      {
        group_address_long: "1/4/1",
        group_address_short: "1/4/2",
        group_address_position_feedback: "1/4/3",
        group_address_position: "1/4/4",
        travel_time_down: 50,
        travel_time_up: 60,
      }

Binary Sensor

Renamed class Switch to BinarySensor. Plase rename the section within configuration:

groups:
  binary_sensor:
    Kitchen.3Switch1:
      group_address: "5/0/0"

Sensors with value_type=binary are now integrated into the BinarySensor class:

groups:
  binary_sensor:
    SleepingRoom.Motion.Sensor:
      { group_address: "6/0/0", device_class: "motion" }
    ExtraRoom.Motion.Sensor: { group_address: "6/0/1", device_class: "motion" }

The attribute significant_bit is now only possible within binary_sensors:

groups:
  binary_sensor_motion_dection:
    Kitchen.Thermostat.Presence:
      { group_address: "3/0/2", device_class: "motion", significant_bit: 2 }

Switch

Renamed Outlet to Switch (Sorry for the confusion...). The configuration now looks like:

groups:
  switch:
    Livingroom.Outlet_1: { group_address: "1/3/1" }
    Livingroom.Outlet_2: { group_address: "1/3/2" }

Within Light class i introduced an attribute group_address_brightness_state. The attribute group_address_state was renamed to group_address_switch_state. I also removed the attribute group_address_dimm (which did not have any implemented logic).

Version 0.6.2 - Released 2017-07-24

XKNX Tunnel now does hartbeat - and reopens connections which are no longer valid.

Version 0.6.0 - Released 2017-07-23

Using asyncio interface, XKNX has now to be stated and stopped asynchronously:

import asyncio
from xknx import XKNX, Outlet

async def main():
    xknx = XKNX()
    await xknx.start()
    outlet = Outlet(xknx,
                    name='TestOutlet',
                    group_address='1/1/11')
    outlet.set_on()
    await asyncio.sleep(2)
    outlet.set_off()
    await xknx.stop()

# pylint: disable=invalid-name
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()

sync_state was renamed to sync:

await sensor2.sync()
```
