So, after my post here yesterday, I solved that problem. Now I am having issues getting Appdaemon to trigger a GPIO port.
I’ve set up a switch and an automation that performs this perfectly, but I just cannot get my pythons script to do it.
Here is my script:
import appdaemon.plugins.hass.hassapi as hass
import RPi.GPIO as GPIO
from time import sleep
class FirstFunction(hass.Hass):
def initialize(self):
self.log("Hello from AppDaemon")
self.log("You are now ready to run Apps!")
self.listen_state(self.trigger, "input_boolean.trigger_first_function")
def trigger(self, entity, attribute, old, new, kwargs):
self.log("Triggering")
# Board Settings
GPIO.setmode(GPIO.BOARD)
GPIO.setup(14, GPIO.OUT)
GPIO.output(14, 1)
sleep(10)
self.log("Finished triggering")
I get the following output:
2018-11-02 08:43:09.913786 INFO circuit: Hello from AppDaemon
2018-11-02 08:43:09.924024 INFO circuit: You are now ready to run Apps!
2018-11-02 08:43:36.672094 INFO circuit: Triggering
But it never completes the function.
The following error is in the log file, but earlier, and doesn’t appear in the most recent restart??
File “/config/appdaemon/apps/script.py”, line 2, in <module> import RPi.GPIO as GPIO
ModuleNotFoundError: No module named ‘RPi’
If this is the problem, I’m struggling to work out how to correctly install this module. What am I doing wrong?
yup thats the problem.
you try to use a lib called RPI that you didnt install.
how is your setup?
hassio, HA and AD in seperate venvs, docker?
Hi Rene,
Forgive my lack of knowlege, I’m not entirely sure what you mean. I installed Hass.io on the RPi 2 Model B. Then the Appdaemon add-on. I’m not using Docker (that I’m aware of).
Thanks for your help.
i dont use hassio myself, but i know that somewhere in the configuration from the appdaemon addon you can give the libs that you want to have installed.
in your case that is the RPI lib
Seems obvious now. I forgot about that big of config…

if that doesnt work i am out of options i guess.
then you better find help in the hassio section.

Any last ideas?
all i every time do is googling for the error and see if someone else had it and what packages come up.
in this case i found this page
yeah it goes about installing a different program, but on the page i find 3 different solutions:
install musl-dev or
install libc-dev or
install linux-headers
all would be system packages and i dont know whit which to go
then i added gpio to my search and found this:
http://forum.tinycorelinux.net/index.php?topic=20221.0
and they also talk about linux-headers, so i would go with that.
and yeah you are getting closer 
Thanks for that. I google every time as well, I just struggle actually interpreting some of the issues I find.
adding linux-headers to the config errored.
But, the following config installs with no problems:
{
"log_level": "info",
"system_packages": [
"gcc",
"libc-dev",
"python3-dev"
],
"python_packages": [
"RPi.GPIO"
]
}
Now I’m getting another error in my code, but I’m researching that first.
Thank you so much for all your help!

I don’t know if this deserves a separate issue or not. It is related, but a distinct issue.
Now I’m getting the following error in Appdaemon logs:

I’ve found that if I could run:
sudo adduser hass gpio
Then it may fix the issue, but I don’t think I can run this command since I am using HassOS?
If I was running Home Assistant in a docker env I would be able to, is that correct?
So now, to proceed, I need to swap to docker, is that correct?
you dont want to run appdaemon as root (sudo)
yeah, the problem with this is that you try to do advanced stuff with a system developed for noob use.
so you runin to all kind of trouble that normally would be easier to repair.
it seems the AD user which is probably the same as the hass user isnt able to read or write to /dev/mem
the whole dev dir is owned by root.
you could try to see if you could find the dir dev/mem and change the access so that the user running AD can access it. or add root access to the user. both solutions probably wont be easy on hassos and you need root access. (which is possible but not easy on default)
i would see if you get any response when you ask this in the hassio section. (maybe other have tried to use gpio also)
that said i googled for homeassistant gpio hassio and i noticed that there is a default component for home assistant.
so you might have travelled the wrong way.
add the gpio to your home assistant and then you can control them with appdaemon as well.
It took hours for me but this is the runing version on my hassio.

So what did you do, to run it as root.
I did the same implementation but still have the no Access problem.
actually, I couldn’t remember the case. Since I got other problems for controlling the relay, I have moved to venv version of the home assistant. I’m using a bottle script as a web service to trigger the relay.
Like a number of others on this forum and elsewhere, I have been trying to use
Appdaemon on a Raspberry pi to read data from GPIO pins and use it in Home Assistant.
In my case I’m trying to read the codes received by a 433MHz receiver attached to the pi
to GPIO PIN 27 using the rpi_rf module’s rpi-rf_receive.py script
(https://github.com/milaq/rpi-rf/blob/71fbe0507588cadd0e58978d2ed72a3cb5994f16/scripts/rpi-rf_receive)
But no luck as I keep getting this error:
File “/usr/lib/python3.8/site-packages/rpi_rf/rpi_rf.py”, line 188, in enable_rx
GPIO.setup(self.gpio, GPIO.IN)
RuntimeError: No access to /dev/mem. Try running as root!
Firstly, in my setup (Hass.io 32 bit for Raspberry pi 3b) there is no such directory as
/dev/mem
There is however this one
/sys/class/gpio
and when I enable the Raspberry PI GPIO integration in the configuration.yaml for pin 27
the folder GPIO27 appears in the above directory and events accrue in Home Assistant’s database.
It seems to be a permissions problem for AD apps accessing the GPIO pins of the pi.
So then I wondered what user Appdaemon apps run under and could I elevate that user’s permissions?
According to this little App I wrote it is actually the root user!
But root must have access to the GPIOs musn’t it?
Or is this a red herring?
And isn’t the advice not to run Appdaemon under the root user?
import appdaemon.plugins.hass.hassapi as hass
import os
import pwd
class DetectMotion(hass.Hass):
def initialize(self):
self.log("ok WE GOT THIS FAR now................")
self.listen_now()
def listen_now(self):
self.log(pwd.getpwuid( os.getuid() )[ 0 ])
By the way I do have this in my Appdaemon configuation and all appears to go well according to the
Appdeamon logs.
system_packages: []
python_packages:
- argparse
- datetime
- RPi.GPIO

Is there any way to fix this permissions problem without having to set up Home Assistant using venvs
or more complex onboarding?
Thanks in advance.
sorry, but i cant help with permissions on hassio.
i have never used it, and the permissions that the addon (AD docker) has is out of the reach from appdaemon.
not long ago i installed AD on a PI zero.
just a simple pip install, and i have working apps that use gpio
hassio is a very restricted area, to make sure that simple users dont come into trouble. and it also restricts the possibilities from AD.
so i see 2 ways to go:
- forget about hassio, or install hassio on another device then the PI that wants to use GPIO
- get in touch with frenck, and see if he can tell you how to get the needed permissions.
dont forget: AD is independant. it doesnt need to be on the same device that you run home assistant on. so its possible to have hassio on 1 PI and AD on another PI.
