Listen for events on a zigbee2mqtt service.

Triggers:

Requires:

__init__(host: Optional[str] = None, port: Optional[int] = None, base_topic='zigbee2mqtt', tls_cafile: Optional[str] = None, tls_certfile: Optional[str] = None, tls_keyfile: Optional[str] = None, tls_version: Optional[str] = None, tls_ciphers: Optional[str] = None, username: Optional[str] = None, password: Optional[str] = None, client_id: Optional[str] = None, *args, **kwargs)[source]
Parameters:

  • host – MQTT broker host (default: host configured on the zigbee.mqtt plugin).

  • port – MQTT broker port (default: 1883).

  • base_topic – Prefix of the topics published by zigbee2mqtt (default: ‘zigbee2mqtt’).

  • tls_cafile – If TLS/SSL is enabled on the MQTT server and the certificate requires a certificate authority to authenticate it, ssl_cafile will point to the provided ca.crt file (default: None)

  • tls_certfile – If TLS/SSL is enabled on the MQTT server and a client certificate it required, specify it here (default: None)

  • tls_keyfile – If TLS/SSL is enabled on the MQTT server and a client certificate key it required, specify it here (default: None) :type tls_keyfile: str

  • tls_version – If TLS/SSL is enabled on the MQTT server and it requires a certain TLS version, specify it here (default: None)

  • tls_ciphers – If TLS/SSL is enabled on the MQTT server and an explicit list of supported ciphers is required, specify it here (default: None)

  • username – Specify it if the MQTT server requires authentication (default: None)

  • password – Specify it if the MQTT server requires authentication (default: None)

  • client_id – MQTT client ID (default: <device_id>-zigbee-mqtt, to prevent clashes with the platypush.backend.mqtt.MqttBackend client_id.

property daemon

A boolean value indicating whether this thread is a daemon thread.

This must be set before start() is called, otherwise RuntimeError is raised. Its initial value is inherited from the creating thread; the main thread is not a daemon thread and therefore all threads created in the main thread default to daemon = False.

The entire Python program exits when only daemon threads are left.

getName()

Return a string used for identification purposes only.

This method is deprecated, use the name attribute instead.

property ident

Thread identifier of this thread or None if it has not been started.

This is a nonzero integer. See the get_ident() function. Thread identifiers may be recycled when a thread exits and another thread is created. The identifier is available even after the thread has exited.

isDaemon()

Return whether this thread is a daemon.

This method is deprecated, use the daemon attribute instead.

is_alive()

Return whether the thread is alive.

This method returns True just before the run() method starts until just after the run() method terminates. See also the module function enumerate().

join(timeout=None)

Wait until the thread terminates.

This blocks the calling thread until the thread whose join() method is called terminates – either normally or through an unhandled exception or until the optional timeout occurs.

When the timeout argument is present and not None, it should be a floating point number specifying a timeout for the operation in seconds (or fractions thereof). As join() always returns None, you must call is_alive() after join() to decide whether a timeout happened – if the thread is still alive, the join() call timed out.

When the timeout argument is not present or None, the operation will block until the thread terminates.

A thread can be join()ed many times.

join() raises a RuntimeError if an attempt is made to join the current thread as that would cause a deadlock. It is also an error to join() a thread before it has been started and attempts to do so raises the same exception.

property name

A string used for identification purposes only.

It has no semantics. Multiple threads may be given the same name. The initial name is set by the constructor.

property native_id

Native integral thread ID of this thread, or None if it has not been started.

This is a non-negative integer. See the get_native_id() function. This represents the Thread ID as reported by the kernel.

on_message(msg)

Callback when a message is received on the backend. It parses and posts the message on the main bus. It should be called by the derived classes whenever a new message should be processed.

Parameters:

msg – Received message. It can be either a key-value dictionary, a platypush.message.Message object, or a string/byte UTF-8 encoded string

on_stop()

Callback invoked when the process stops

register_service(port: Optional[int] = None, name: Optional[str] = None, srv_type: Optional[str] = None, srv_name: Optional[str] = None, udp: bool = False, properties: Optional[Dict] = None)

Initialize the Zeroconf service configuration for this backend.

Parameters:

  • port – Service listen port (default: the backend port attribute if available, or None).

  • name – Service short name (default: backend name).

  • srv_type – Service type (default: _platypush-{name}._{proto}.local.).

  • srv_name – Full service name (default: {hostname or device_id}.{type}).

  • udp – Set to True if this is a UDP service.

  • properties –

    Extra properties to be passed on the service. Default:

    {
    "name": "Platypush",
    "vendor": "Platypush",
    "version": "{platypush_version}"
}

run()[source]

Starts the backend thread. To be implemented in the derived classes if the loop method isn’t defined.

send_event(event, **kwargs)

Send an event message on the backend.

Parameters:

event – Event to send. It can be a dict, a string/bytes UTF-8 JSON, or a platypush.message.event.Event object.

send_message(msg, topic: Optional[str] = None, **kwargs)

Sends a platypush.message.Message to a node. To be implemented in the derived classes. By default, if the Redis backend is configured then it will try to deliver the message to other consumers through the configured Redis main queue.

Parameters:

  • msg – The message to send

  • queue_name – Send the message on a specific queue (default: the queue_name configured on the Redis backend)

send_request(request, on_response=None, response_timeout=5, **kwargs)

Send a request message on the backend.

Parameters:

  • request – The request, either a dict, a string/bytes UTF-8 JSON, or a platypush.message.request.Request object.

  • on_response (function) – Optional callback that will be called when a response is received. If set, this method will synchronously wait for a response before exiting.

  • response_timeout (float) – If on_response is set, the backend will raise an exception if the response isn’t received within this number of seconds (default: None)

send_response(response, request, **kwargs)

Send a response message on the backend.

Parameters:

  • response – The response, either a dict, a string/bytes UTF-8 JSON, or a platypush.message.response.Response object.

  • request – Associated request, used to set the response parameters that will link them

setDaemon(daemonic)

Set whether this thread is a daemon.

This method is deprecated, use the .daemon property instead.

setName(name)

Set the name string for this thread.

This method is deprecated, use the name attribute instead.

start()

Start the thread’s activity.

It must be called at most once per thread object. It arranges for the object’s run() method to be invoked in a separate thread of control.

This method will raise a RuntimeError if called more than once on the same thread object.

stop()

Stops the backend thread by sending a STOP event on its bus

unregister_service()

Unregister the Zeroconf service configuration if available.
