Filter Monitor

This Klipper plugin monitors the runtime of air filters (Nevermore, THE FILTER, etc), and triggers notifications and/or executes G-code when threshold conditions, such as max runtime or lifetime hours, are met. These monitoring checks also occur on pre-defined system events and keep track of total fan runtime.

Installation

To install this plugin, first ensure that you already have Klipper, Moonraker, and a WebUI (Mainsail, Fluidd, or Octoprint) installed on your printer. If not, you can use KIAUH to facilitate the process.

Then, execute the following command over SSH. The script will clone this GitHub repository to your device's home directory, and symlink the required files into the Klipper "extras" folder.

wget -O - https://raw.githubusercontent.com/blankhaus/klipper-filter_monitor/main/install.sh | bash

Then, add the following to moonraker.conf to enable automatic updates:

[update_manager filter_monitor]
type: git_repo
path: ~/klipper-filter_monitor
origin: https://github.com/blankhaus/klipper-filter_monitor.git
