you must enable spi in raspi-config

All of this should be automatic in the openplotter-pypilot plugin script. Did you install it? Maybe it is out of date:

I am waiting for openplotter beta version to verify everything is working without such manual steps

OK, you were right, the SPI interface was off but it didn't fix the problem. When I tried to update pypilot I got errors for Python3-all and debhelper. I installed those programs and I still couldn't get it to load. I rebooted and now I get the following:

pi@openplotter:~ $ cd openplotter-pypilot
pi@openplotter:~/openplotter-pypilot $ dpkg-buildpackage -b

What did you get running pypilot_hat once the spi interface was enabled and permissions granted?

The display came on. I moved it accidentally whil the program was still running. I hope that wasn't bad. The output in terminal was as follows:

It seems openplotter uses an outdated version of pypilot and the hat service is already running

It seems strange then that the display is not being used. In any case what if you stop all the services eg:
sudo service pypilot stop
sudo service pypilot_hat stop

Then upgrade pypilot:
git clone https://github.com/pypilot/pypilot
cd pypilot
sudo python3 setup.py install

Now try again
sudo service pypilot start
and then
sudo pypilot_hat

It should work now and you can set the service at boot with
sudo service pypilot_hat start

you have version 2.1.1 of the openplotter-pypilot plugin. To figure out what version of pypilot you can run:
pypilot_client ap.version

if by turn off you mean the backlight, then no the command has no effect on the backlight.

Thanks for reporting this. I fixed one issue and created another. So I try again to fix the dependency script to install dependencies needed to run the script...

Please try again:
cd pypilot
git pull
sudo python3 setup.py install


Thanks for the patience, it will work soon...

I rand the scripts above and it did a lot of stuff but its still doing the same thing. I accidentally closed the terminal and lost most of the output. Below is what I got when I ran it again.

Before I forget, I wanted to ask about the keypad and the waterproof cables you used. I ordered a keypad that looks like the one you used but it has 12 wires going to it but the hat only has five pins. Do you have a recommended keypad? I saw somewhere where you had the waterproof cables shown but I cannot find them in the forum anywhere.
