CatPrinter

Driver, Telegram bot & apps for the thermal "cat printer"

Install script:

Before start:

You need API keys from : Telegram Bot, OpenWeather and OpenAI

sudo chmod +x install.sh && sudo ./install.sh

Choose the Default install : [D] for normal installation

After, you can choose the Web install : [W] for the PHP web log file (installed in /var/www/html/catlog/index.php)

(Start install or [S] is for my personal use case)

Reboot after the execution of this script

sudo reboot

You can, if you have Nextcloud Talk app, add a channel_id to have a monitoring bot for the status of the catprinter, to be specified in the configuration files. For this, opens the discussion where you want your bot to send you notifications via the Nextcloud Talk web application. Retrieve the channel ID at the end of the discussion URL. For example, in the following link:

https://your-nextcloud-instance/index.php/call/ybz3dgu#/

The channel ID is: ybz3dgu
