# syncmqtt

sync your data with mqtt

## example usage:

```

from syncmqtt import qtt, attr, sub, conn

@qtt()

class SyncedMqtt:

    # push_on_set will pub to topic when assign new value

    # sync wil update value when new message from topic

    # json means value are serialized before send and parsed after receive 

    test_a = attr(val='test_a', topic='/a', push_on_set=True, sync=True, retained=True)

    test_b = attr(val=20, topic='/b', push_on_set=False, sync=True, json=True)  

    test_c = attr(val='test_c', topic='/c', push_on_set=True, sync=False, retained=False)

        

    @sub(topic='/c', json=True)  # make sure test_cb is called when topic='/c' got new message

    def test_cb(self, val):

        print(val)

        self.test_a = val

async def main():

    conn.connect(broker='mqtt://localhost:8000', live_topic='/test_status')

    # init with last_will off => /test_status

    # pub on => /test_status retained, let other know I'm online

    # during conn.connect

    

    sq = SyncedMqtt()  # if use qttclass before conn.connect, raise error

    sq.test_c = 'hello' 

    # pub hello => /c

    # test_cb

    # print hello

    # set test_a

    # pub hello => /a

    conn.destory()  # stop connection

    

    # mqtt connect broken and off => /test_status base on last wil setting

```
