HABApp

Easy automation with MQTT and/or openHAB

HABApp is a asyncio/multithread application that connects to an openhab instance and/or a MQTT broker. It is possible to create rules that listen to events from these instances and then react accordingly.

Goals

The goal of this application is to provide a simple way to create home automation rules in python. With full syntax highlighting and descriptive names it should almost never be required to look something up in the documentation

Examples

MQTT Rule example

import datetime
import random

import HABApp
from HABApp.core.events import ValueUpdateEvent


class ExampleMqttTestRule(HABApp.Rule):
    def __init__(self):
        super().__init__()

        self.run_every(
            time=datetime.timedelta(seconds=60),
            interval=datetime.timedelta(seconds=30),
            callback=self.publish_rand_value
        )

        self.listen_event('test/test', self.topic_updated, ValueUpdateEvent)

    def publish_rand_value(self):
        print('test mqtt_publish')
        self.mqtt.publish('test/test', str(random.randint(0, 1000)))

    def topic_updated(self, event):
        assert isinstance(event, ValueUpdateEvent), type(event)
        print( f'mqtt topic "test/test" updated to {event.value}')

Openhab rule example

import HABApp
from HABApp.core.events import ValueUpdateEvent, ValueChangeEvent
from HABApp.openhab.events import ItemStateEvent, ItemCommandEvent, ItemStateChangedEvent

class MyOpenhabRule(HABApp.Rule):

    def __init__(self):
        super().__init__()

        # Trigger on item updates
        self.listen_event( 'TestContact', self.item_state_update, ItemStateEvent)
        self.listen_event( 'TestDateTime', self.item_state_update, ValueUpdateEvent)

        # Trigger on item changes
        self.listen_event( 'TestDateTime', self.item_state_change, ItemStateChangedEvent)
        self.listen_event( 'TestSwitch', self.item_state_change, ValueChangeEvent)

        # Trigger on item commands
        self.listen_event( 'TestSwitch', self.item_command, ItemCommandEvent)

    def item_state_update(self, event):
        assert isinstance(event, ValueUpdateEvent)
        print( f'{event}')

    def item_state_change(self, event):
        assert isinstance(event, ValueChangeEvent)
        print( f'{event}')

        # interaction is available through self.openhab or self.oh
        self.openhab.send_command('TestItemCommand', 'ON')

    def item_command(self, event):
        assert isinstance(event, ItemCommandEvent)
        print( f'{event}')

        # interaction is available through self.openhab or self.oh
        self.oh.post_update('TestItemUpdate', 123)
