Bi-monthly INDI Library released with new drivers and bug fixes.

Help a noob set up an Indi scripting environment to run a Github goto-telescope (Dob) alignment script.

Thank you for looking! Background: I’ve been experimenting with using the Indi Plate-Solving module to correct alignment slop in my Dob/Sky Safari/Nexus DSC/Servocat setup. I was able to achieve getting the RPi4/Stellarmate environment working together with my setup, but realized I would need to script Ekos in order to automate a solve/align after each goto/slew. I discovered a link on Cloudynights pointing to a Github project which looks very similar to what I would like to achieve. 

github.com/gordtulloch/PiINDIControlPad/...6a2abe4cc452034c6ba9  
INSTALLATION   
   On Debian or Ubuntu:  
sudo apt-add-repository ppa:mutlaqja/ppa  
sudo apt-get update  
sudo apt install git indi-full gsc kstars-bleeding swig libcfitsio-dev libnova-dev python3-tk  
   git clone github.com/gordtulloch/PiINDIControlPad.git  
cd PiINDIControlPad  
pip3 install --user pipenv  pipenv install astropy pyindi-client numpy tzlocal tk 

I’m having some issues completing the installation instructions: 
My first attempt involved using my Stellarmate OS and trying to apply the installation “on top”. Raspian doesn’t seem to recognize the “ppa” structure. I created a new Ubuntu (20.10) install but am having issues with 
1)      Gsc  Module not found
2)      Pyindi-client  Error 
Also, Ubuntu seems incredibly slow compared to a Rasbian install. Could there be another option which would perform better? Or perhaps a method to make this project compatible with Stellarmate? 

Would someone be kind enough to help me work through these issues? I would be happy to pay for your time or contribute to your favorite charity. Any suggestions are appreciated!

Hi!,
I'm not an expert at all, but as stated in raspberrypi.stackexchange.com/a/46933 to be able to issue the command
sudo apt-add-repository ppa:mutlaqja/ppa
inside Raspbian, you need to install the packege software-properties-common beforehand with
sudo apt-get install software-properties-common

Hope it's not too late :-)

May I ask you how did you connect the Servocat / Nexus DSC setup with ekos?
I've been reading and it sems like Nexus DSC is comptible with LX200 protocol, but I'm planning on upgrading my setup and would like to double check for indi compatibility.

Thx in advance

May I ask you how you got Nexus DSC / ServoCAT setup to talk to Indi / Ekos?
I've been reading Nexus DSC is LX200 compatible, but I would like to double check before upgrading my setup.

Hello. Thank you for the response. I'm pursuing a different method which doesn't use INDI, so I don't have that configuration available at the moment. But, as I remember: connect the RPi to the wifi access point of the Nexus, setup the LX200 Basic mount configuration in INDI to use Ethernet and configure the IP address and port number (which Nexus uses) within INDI. The Nexus becomes the wifi hub and will sync with any movement instructions from INDI. If using Sky Safari, just connect Sky Safari to Nexus in the same way. Nexus will sync to any commands from Sky Safari plus echo the commands to INDI and vice versa.
