Python class library for generating and sending data to the Home Assistant via MQTT (AutoDiscovery) of data from sensors and devices.
from HaMqttDevice import *
mqtt_client = mqtt.Client("user")
mqtt_client.on_connect = on_connect
mqtt_client.on_message = on_message
mqtt_client.username_pw_set("user", "pass")
mqtt_client.connect("mqtt.mqtt.ru", 1883, 60)
mqtt_client.loop_forever()example_device = Device.from_config("example_device.yaml")
inside_temperature_sensor = Sensor(
mqtt_client,
"Temperature 1",
parent_device=example_device,
unit_of_measurement="°C",
topic_parent_level="inside",
)
outside_temperature_sensor = Sensor(
mqtt_client,
"Temperature 2",
parent_device=example_device,
unit_of_measurement="°C",
topic_parent_level="outside",
)
inside_temperature_sensor.send(22)
outside_temperature_sensor.send(5)If the hardware sensor is used solely to publish to mqtt, the Sensor can fetch
the value by itself so keeping a reference to both the hardware and the mqtt
sensor is not required.
For example:
inside_temperature_sensor.set_value_read_function(lambda: round(hardware_sensor.temperature, 2))From here publishing to the mqtt server would be:
inside_temperature_sensor.send()HA_gps = Tracker(mqtt_client, "MotoBoard GPS")
HA_gps.send(55.5, 37.5, 0)HA_alarm = Binary(mqtt_client, "MotoBoard alarm", "mdi:alarm-light")
HA_alarm.send(1)
