Installation problem (novice)

veqlargh commented 2 years ago

Hi. I am new to this kind of stuff. I have installed HA to my RPI3 and i want to hardwire my sensors and relay to RPI3. I came across the mqtt-io. I have an installation problem to start with. I have done this installation pip3 install mqtt-io and it worked. when i tried to execute next python3 -m mqtt_io config.yml I got an error FileNotFoundError: [Errno 2] No such file or directory: 'config.yml' Do I have to create a config.yml file myself - if yes, where do i create it? Is there something else I should do before? Or is there maybe some tutorial on how to do this stuff. Sorry for so many questions but I would really like to learn :)

Hi, there are some config examples in the repo (config.example.yml). Feel free to use the needed information for your hardware and create your own config.yml Locate it, where it fits for you. e.g. pi home directory "/home/pi/config.yml". Depending on the user you're running mqtt_io, you should give the full path of the config file. python3 -m mqtt_io /home/pi/config.yml

Thank you for explaining.

Now I ran into another issue. When I execute the config file I get one of the errors.

If i add a

gpio_modules:
  - name: MyPI
    module: raspberrypi

to the config file I get this error:

Config did not validate due to errors in the following sections:
gpio_modules:
  MyPI:
  - GPIO module 'MyPI' does not have any digital_input or digital_output configs

But if I remove upper config lines I get error as below. Am I doing something wrong again? The config file is below the error.

Hey,

the first problem was solved by you (mqtt_io does not like unused modules.
your second problem: mqtt_io tries to install the dht22 lib, but has problems:
Using legacy 'setup.py install' for Adafruit-DHT, since package 'wheel' is not installed. When wheel is not installed, it tries to build it on its own, but gcc is missing too, so it fails. Maybe you can try pip install wheel manually and try to run mqtt_io again. Good luck
