Kettle

KettleController

class core.controller.kettle_controller.KettleController(cbpi)

Bases: core.controller.crud_controller.CRUDController

The main kettle controller

_is_logic_running(kettle_id)
agitator_off(id)
agitator_on(id)
get_temp(id)
get_traget_temp(id)
handle_automtic_event(id, **kwargs)

Method to handle the event ‘kettle/+/automatic’

Parameters:
  • id – The kettle id
  • kwargs –
Returns:

None
heater_off(id)

Convenience Method to switch the heater of a kettle off

Parameters:id –
Returns:
heater_on(id)

Convenience Method to switch the heater of a kettle on

Parameters:id – the kettle id
Returns:(boolean, string)
init()

This method initializes all actors during startup. It creates actor instances

Returns:
job_stop(key, **kwargs) → None
model

alias of core.database.model.KettleModel

toggle_automtic(id)

Convenience Method to toggle automatic

Parameters:id – kettle id as int
Returns:(boolean, string)

CBPiKettleLogic

class core.api.kettle_logic.CBPiKettleLogic(*args, **kwds)

Bases: core.api.extension.CBPiExtension

Base Class for a Kettle logic.

init()

Code which will be executed when the logic is initialised. Needs to be overwritten by the implementing logic

Returns:None
run()

This method is running as background process when logic is started. Typically a while loop responsible that the method keeps running

while self.running:
await asyncio.sleep(1)
Returns:None
stop()

Code which will be executed when the logic is stopped. Needs to be overwritten by the implementing logic

Returns:None
