Homie
Python 3 implementation of Homie 4.0.0
Class based system to easily add Homie 4.0.0 support to devices.
Supports the Meta, Statistics, and Firmware extensions
Includes ready to use common devices such as switch, dimmer, contact, thermostat, boolean, etc.
Install
pip install Homie4
Note: On Raspbian use
pip3 install Homie4
Temperature Probe Example
Creates a temperature device using a AM2302 sensor.
import Adafruit_DHT
import time
from homie.device_temperature import Device_Temperature
mqtt_settings = {
'MQTT_BROKER' : 'OpenHAB',
'MQTT_PORT' : 1883,
}
try:
temperature_device = Device_Temperature(device_id="temperature-sensor-1",name = "Temperature_Sensor 1",mqtt_settings=mqtt_settings)
sensor = Adafruit_DHT.AM2302
pin = 4
while True:
humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)
print(temperature)
temperature_device.update_temperature(temperature)
time.sleep(5)
except (KeyboardInterrupt, SystemExit):
print("Quitting.")
Dimmer Example
To create a dimmer device requires that a set_dimmer method be provided. When creating a device, all that is required is to provide the MQTT settings. All other requirements of the Homie specification are automatically handled.
import time
from homie.device_dimmer import Device_Dimmer
mqtt_settings = {
'MQTT_BROKER' : 'QueenMQTT',
'MQTT_PORT' : 1883,
}
class My_Dimmer(Device_Dimmer):
def set_dimmer(self,percent):
print('Received MQTT message to set the dimmer to {}. Must replace this method'.format(percent))
super().set_dimmer(percent)
try:
dimmer = My_Dimmer(name = 'Test Dimmer',mqtt_settings=mqtt_settings)
while True:
dimmer.update_dimmer(0)
time.sleep(5)
dimmer.update_dimmer(50)
time.sleep(5)
dimmer.update_dimmer(100)
time.sleep(5)
except (KeyboardInterrupt, SystemExit):
print("Quitting.")
If creating multiple homie devices, you can specify Homie to only use one MQTT connection. This can be an issue on devices with limited resources. For MQTT_SETTINGS add MQTT_SHARE_CLIENT: True.
