I'm trying to make use of the HAT for gathering digital and analog input and giving outputs with a Python program and AWS IoT. This would run indefinitely and send and receive information from my script ideally.
When i try to implement the same in the following manner.
def on_connect(client, userdata, flags, rc):
if rc == 0:
print("Connected to AWS IoT")
client.subscribe(MQTT_TOPIC_SUBSCRIBE)
else:
print("Connection to AWS IoT failed")
def on_message(client, userdata, msg):
print(f"Received message from topic {msg.topic}: {str(msg.payload.decode('utf-8'))}")
message = json.loads(msg.payload)
if "desiredTemperature" in message:
desired_temperature = message["desiredTemperature"]
print(f"Setting desired temperature to: {desired_temperature}")
set_temperature(desired_temperature)

def read_sensors(): temperature = ind.get0_10In(STACK_LEVEL, TEMP_INPUT_CHANNEL) humidity = ind.get0_10In(STACK_LEVEL, HUMIDITY_INPUT_CHANNEL) return temperature, humidity
I get an error stating "An error occurred in the publish thread: [Errno 2] No such file or directory: '/dev/i2c-1'
The program works ideally when i comment out any code with regards to the megaind library and use dummy data.
