0.15.0 Spring cleaning and quality of life changes

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()

Breaking changes

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 . Please rename the section within configuration:

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

Cover

Renamed class Shutter to Cover. Please 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. Please 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()
```
