Can't get it to work. Error from python?
- [Y] I have read the README.md file and visited the Documentation to see if the information there helps.
- Also have gone through the closed issues, but I don't have same errors.
Describe the bug After installing python, I create the yaml file.
pi@pi21:~ $ sudo nano test-config.yml
with the following content
mqtt:
host: core-mosquitto
port: 1883
user: "mqtt"
password: "password"
topic_prefix: /home/temp
# GPIO
gpio_modules:
# Use the Raspberry Pi built-in GPIO
- name: rpi
module: raspberrypi
digital_inputs:
# Pin 0 is an input connected to a doorbell button
- name: Chun
module: rpi
pin: 4
sensor_modules:
- name: dht22
module: dht22
type: DHT22 # can be DHT11, DHT22 or AM2302
pin: 4
sensor_inputs:
- name: temperatureChun
module: dht22
interval: 5 #interval in seconds, that a value is read from the senso>
digits: 4 # number of digits to be round
type: temperature # Can be temperature or humidity
- name: humidityChun
module: dht22
interval: 5 #interval in seconds, that a value is read from the senso>
digits: 4 # number of digits to be round
type: humidity # Can be temperature or humidity```
It's basically just to get the data off the DHT22 sensor.
However, when I run
`
pi@pi21:~ $ python3 -m mqtt_io test-config.yml
`
the following errors appear:

I just want it to run and publish something. I'm listening on homeassistant but there's just nothing
