CUPS

The cups sensor platform uses the open source printing system CUPS to show details about your printers, including the ink levels. It can obtain the information using a CUPS server or by communicating directly with the printer with the Internet Printing Protocol.

Setup

You will need to install the python3-dev or python3-devel package and the development files for CUPS (libcups2-dev orcups-devel) on your system manually (e.g., sudo apt-get install python3-dev libcups2-dev or sudo dnf -y install python3-devel cups-devel) along with a compiler (gcc). This integration doesn’t work out-of-the-box in a container-based setup.

To set up the sensor the “Queue Name” of the printer is needed. The fastest way to get it, is to visit the CUPS web interface at “http://[IP ADDRESS PRINT SERVER]:631” and go to “Printers”.

Configuration

To enable the CUPS sensor, add the following lines to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI.[Learn more] file. After changing the configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI.[Learn more] file, restart Home Assistant to apply the changes. To view the changes, go to Settings > Devices & services > Entities.
