MqttControl

This is project is all about a Class called Communicatable which other classes can inherit and it allows for very easy set up of control through mqtt.

Best to look at an example:

class Example(Communicatable):  
    def __init__(self, mqtt, something=0):  
        Communicatable.__init__(self, mqtt, "example")   # 'example' is the control name
        self.something = something  
        self.mqtt_settable("something")  
        self.mqtt_callable("foo")  
  
    def foo(self, input1, input2, optional1=None, optional2=None):  
        self.something = input1 + input2  
        print(f"{optional1=}, {optional2=}")  

Example inherits the Communicatable class and the simple line self.mqtt_Settable("something") is all that is needed for self.something to be both settable and gettable through mqtt.

Here is an example of how to initialize our Example() class:

from paho.mqtt.client import Client as MqttClient  
client = MqttClient("Test")  
client.connect("localhost")  
client.loop_start()

example = Example(client)

Now example.something can be controlled by connecting to the same mqtt server and posting to example/set:

client.publish("example/set", json.dumps({"something": 15}))
client.publish("example/call", json.dumps(["foo", [1, 2], {"optional1": "hello", "optional2": "dis working?"}]))
