raspberrypi: RuntimeError: Error accessing GPIO. #107

Closed gitmirko closed 1 year ago

gitmirko commented 4 years ago

Hi, I'm struggling with getting the docker container to access the GPIO. I'm running a raspberry pi 3B+ with raspbian. I've attached a AM2302 on pin 4 and configured pi-mqtt-gpio as follow:

mqtt:
  host: 10.0.0.10
  port: 8883
  tls:
    enabled: yes
    cert_reqs: CERT_NONE
    insecure: yes
  user: "rpi"
  password: "FXHucuGYBy7kHR3MtN"
  topic_prefix: home/wohnzimmer

gpio_modules:
  - name: raspberrypi
    module: raspberrypi
    cleanup: no

sensor_modules:
  - name: dht22
    module: dht22
    type: AM2302 # can be  DHT11, DHT22 or AM2302
    pin: 4

sensor_inputs:
  - name: dht22_temperature
    module: dht22
    interval: 4 #interval in seconds, that a value is read from the sensor and a update is published
    digits: 2 # number of digits to be round
    type: temperature # Can be temperature or humidity

  - name: dht22_humidity
    module: dht22
    interval: 4 #interval in seconds, that a value is read from the sensor and a update is published
    digits: 2 # number of digits to be round
    type: humidity # Can be temperature or humidity
logging:
  version: 1
  formatters:
    simple:
      format: "%(asctime)s %(name)s (%(levelname)s): %(message)s"
  handlers:
    console:
      class: logging.StreamHandler
      level: DEBUG
      formatter: simple
      stream: ext://sys.stdout
  loggers:
    mqtt_gpio:
      level: DEBUG
      handlers: [console]
      propagate: yes

This is the output of the container and the log (I've killed the container with CTRL-C):

I'm out of ideas. Could someone help me out?

Best regards Mirko

Hi, you do have the problem with all gpios or only via dht22/Adafruit lib?

gitmirko commented 4 years ago

I've just tried adding an normal pin as output, but even with passing an additional device I get another kind of error:

[...]

    pin: 18

BenjiU commented 4 years ago

docker run --name="mqtt-gpio" --privileged --device /dev/mem --device /dev/gpiomem

https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities says, that you can use --device, if you don't want to use --privileged. May you check one without the other: just --privileged or --device=? syntax on help page, looks different: docker run --device=/dev/sda:/dev/xvdc

gitmirko commented 4 years ago

I've just tried only with --privileged and another try specifying the devices with the syntax from the linked documentation. No luck at all:

same issue for me

Same.

I am having a similar issue but I am trying to run a python script with a php file. Whenever I try to run it i get RuntimeError: No access to /dev/mem. Try running as root!. I am using apache2 to run a webserver and i have setup then index.php file to run a simple python. Anyone know how to solve this error.

Hi, I have the same error, however, it's for the newest version of mqtt_io add-on:

Add-on: MQTT IO
 Expose GPIO modules and digital sensors via MQTT for remote control and monitoring.
-----------------------------------------------------------
 Add-on version: 0.1.3
 You are running the latest version of this add-on.
 System: Home Assistant OS 9.3  (aarch64 / raspberrypi4-64)
 Home Assistant Core: 2022.10.5
 Home Assistant Supervisor: 2022.10.0

I'm using this config:

mqtt:
  host: ...
  port: ...
  user: ...
  password: ...
  topic_prefix: home/depot/climate
  ha_discovery:
    enabled: yes

sensor_modules:
  - name: dht_depot
    module: dht22
    type: DHT22
    pin: 4

sensor_inputs:
  - name: depot_temp
    module: dht_depot
    interval: 10
    digits: 4
    type: temperature
    ha_discovery:
      name: Depot temperature
      device_class: temperature
  - name: depot_humidity
    module: dht_depot
    interval: 10
    digits: 4
    type: humidity
    ha_discovery:
       name: Depot humidity
       device_class: humidity

And here is the log:

2022-11-02 20:37:12 mqtt_io.server [INFO] Connected to MQTT

RuntimeError: Error accessing GPIO.

Is it something wrong with my config? I have tried two different DHT22 devices connected in the same way

BenjiU commented 1 year ago

How do you execute it? Looks like a privilege problem!

mchmielarz commented 1 year ago

I simply added the add-on to the HA and clicked the run button. I'm using HASSIO so I assumed it runs with full access to everything.

BenjiU commented 1 year ago

Hmm, okay. That's a setup I do not have, so I may not help you. I guess it's a HASSIO problem/decision? https://community.home-assistant.io/t/access-rpi-gpio-in-custom-addon/383429 <-- Says 64bit can't use GPIOs https://community.home-assistant.io/t/removal-of-gpio-support/372222/162 <-- no direct use of GPIO, so the addons won't be, too, I guess.

mchmielarz commented 1 year ago

So I would have to install it with other distribution and then install HA and mqtt.io separately. Thanks for help! I'll back with my findings here

BenjiU commented 1 year ago

@mchmielarz i will close this issue, because it was originally related to docker (2020). Please create a new issue or use #293 Thanks!
