Thanks for the work that you did on creating this plugin. I also struggled to get the initial steps to complete, and kept on getting a message about not being able to find run.sh. I ended up just going through the install process using the https://community.home-assistant.io/t/add-on-hassos-i2c-configurator Add On, and then installing this one to run the OLED software. Looking forward to future development on it!
