Hello,

i found your project when I was looking for another use for my Waveshare 2.13" display. My hardware requirements are the same as you listed. I use an RPi Zero WH, pihole in version V5.14.1 and the 2.13inch E -Ink display HAT for Raspberry Pi.

When I run the command sudo python3 examples/epd_2in13_V2_test.py, the demo plays correctly on the display.

I've followed your guide closely, but I get errors with both ways to install pihole-dashboard.

Here the error messages:

root@falconstar:~# sudo pip3 install pihole-dashboard Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple/ Collecting pihole-dashboard Using cached pihole_dashboard-1.0.2-py3-none-any.whl (140 kB) Collecting Pillow>=8.2.0 Using cached https://www.piwheels.org/simple/pillow/Pillow-9.3.0-cp39-cp39-linux_armv6l.whl (1.1 MB) Requirement already satisfied: netifaces>=0.10.9 in /usr/local/lib/python3.9/dist-packages (from pihole-dashboard) (0.11.0) Collecting pihole-dashboard Using cached pihole_dashboard-1.0.1-py3-none-any.whl (137 kB) Using cached https://www.piwheels.org/simple/pihole-dashboard/pihole_dashboard-1.0.0-py3-none-any.whl (124 kB) ERROR: Cannot install pihole-dashboard==1.0.0, pihole-dashboard==1.0.1 and pihole-dashboard==1.0.2 because these package versions have conflicting dependencies.

The conflict is caused by: pihole-dashboard 1.0.2 depends on waveshare-epd pihole-dashboard 1.0.1 depends on waveshare-epd pihole-dashboard 1.0.0 depends on waveshare-epd

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

The 2nd method shows these messages:

root@falconstar:~/pihole-dashboard# sudo pip3 install . Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple/ Processing /root/pihole-dashboard Preparing metadata (setup.py) ... done ERROR: Could not find a version that satisfies the requirement waveshare-epd (from pihole-dashboard) (from versions: none) ERROR: No matching distribution found for waveshare-epd

I can't find a solution to these problems, do you have any ideas or tips?

Best regards, Carsten

Hi,

I like the concept so have tried installing it as you describe, however I have an issue.

The display only works when I do ‘sudo pihole-dashboard-draw’ manually. The cron is not refreshing the display automatically. Any thoughts?

Hello I followed your instructions but then I got stuck when i tried to test the screen itself when i went to put in sudo python epd_2in13_V2_test.py it gave me this in return Traceback (most recent call last): File "epd_2in13_V2_test.py", line 11, in from waveshare_epd import epd2in13_V2 File "/home/pi/newdisplaything/e-Paper/RaspberryPi_JetsonNano/python/lib/waveshare_epd/epd2in13_V2.py" , line 32, in from . import epdconfig File "/home/pi/newdisplaything/e-Paper/RaspberryPi_JetsonNano/python/lib/waveshare_epd/epdconfig.py", line 152, in implementation = RaspberryPi() File "/home/pi/newdisplaything/e-Paper/RaspberryPi_JetsonNano/python/lib/waveshare_epd/epdconfig.py", line 47, in init import RPi.GPIO ImportError: No module named RPi.GPIO

whats weird is ive tried installing the RPI.GPIO a couple different ways but i feel like i must of missed something but if you could possibly point me in the right direction i would really appreciate any help thanks in advanced

would mention that SPI interface needs to be turned on in raspi-config in order for e-ink screen to function.

would mention that init.py needs to be modified if using ethernet instead of wi-fi (change Interface = "wlan0" to "eth0")

After the last update of Pihole/adminLTE, the display on the e-paper no longer works. The same problem existed with a PiTFT and PiOLED display. The solution was communicated to me at https://github.com/pi-hole/AdminLTE/issues/2467 and consisted in the adaptation of api_url = 'http://localhost/admin/api.php?summary&auth=abcdef123456789'.

Unfortunately this doesn't work if I enter it in the init.py among
def update(): url = "http://127.0.0.1:{}/admin/api.php".format(PIHOLE_PORT) r = json.load(urllib.request.urlopen(url))

How should the adjustment be correct?

hi,

i followed your instructions to install everything (Incl. Waveshare etc.). The display is working so far. But after installation of Pihole-Dashboard and rebooting, the display is not drawing. I tried with sudo pihole-dashboard-draw but it didn't work:

Traceback (most recent call last):
  File "/usr/local/bin/pihole-dashboard-draw", line 23, in <module>
    pihole_dashboard.update()
  File "/usr/local/lib/python3.9/dist-packages/pihole_dashboard/__init__.py", line 91, in update
    unique_clients = r['unique_clients']
KeyError: 'unique_clients'

Anything i could try?
