Hi @andlo,
thanks for quick response, now the skill installs without error, …, but another one followed:
mycroft.skills.core:load_skill:159 - ERROR - Failed to load skill: picroft-google-aiy-voicekit-skill.andlo Traceback (most recent call last): File "/opt/venvs/mycroft-core/lib/python3.4/site-packages/mycroft/skills/core.py", line 143, in load_skill raise e File "/opt/venvs/mycroft-core/lib/python3.4/site-packages/mycroft/skills/core.py", line 139, in load_skill skill.initialize() File "/opt/mycroft/skills/picroft-google-aiy-voicekit-skill.andlo/__init__.py", line 21, in initialize GPIO.setup(25,GPIO.OUT) RuntimeError: No access to /dev/mem. Try running as root!
after some research on the error message I found out that user mycroft must be member in usergroups for the devices it tries to access. In the end following helped:
After reboot now the LED lights up when Mycroft is listening, pressing button short makes Mycroft listen and pressing long makes it stop speaking. Fantastic work!
Unfortunately now I can no longer control volume (by volume-skill, alsamixer stills works). I should add that my AIY-PiCroft is running Debian-Jessie and is somewhat “broken” as this is my developement and testing device, so it is probably my installation and not your skill causing the problem…
I am running the Picroft Strech image, and dont have same issues. So it is relatet to your “special” installation or the old jessie picroft.
I cant see why it should do anything regarding volume-skill though. That is strange.
As nothing seemed working, I looked to the logs and find nothing, but I was thinking to add
“LOGGER = getLogger(_name_)” somewhere to keep track of the skill.
Following Dominik’s post I checked the skills.log and found the same error during installation:
20:16:24.491 - mycroft.skills.core:load_skill:159 - ERROR - Failed to load skill: picroft-google-aiy-voicekit-skill.andlo

I copied sudo intructions from Dominik and it works well but for the volume I didn’t check it.
Thanks I amhappy to hear that it works - and proud that I actually did make a skill that seems to work I have been reading a lot of stuff and did look at a lot of code to figure out how to get there.
Are you @henridbr using Picroft Strech or Jessie or a self made Mycroft installation?
I do not see the No access to /dev/mem error on my picrofts. But that could be that picroft is running whith root pivileges and that is not normal rasbian way. I am using a stock picroft strech installation.
I will add some logging if I can, but right now I cant figure out how to fix No access to /dev/mem in the skill installation Would be glad if someone did know how to do that.
I am also following the track of @tjoen’s files because I have begun by his disk image.
Picroft has been updated to 18.8.3 during reboots.
I saved an image of my SD card in order to start on this basis every time I need it.
The button and light issues are linked to the python environment which is under python 2 and python 3.
Right now the button and light are working well after:
installing python3 version of Websocket and RPi.GPIO:
sudo mycroft-pip install websocket-client==0.32.0
sudo pip3 install RPi.GPIO
modifying mbus.py, button.py and lights.py to work under python3. The changes are:
print"" to print()
python to python3
modifying custom_setup.sh. Change python to python3
At this point, the led is always pulsing quickly instead of off when nothing occurs.
To fix that I modified my_led_state to (LED_OFF).
Now it’s working, and after spending time trying to understand things I have never seen before, I am thinking about python3 which could be the default. I don’t know.
I amhappy to hear that it works - and proud that I actually did make a skill that seems to work 
Would be glad if someone did know how to do that.
