homebus-dremel

This is a simple HomeBus data source which publishes printer status for Dremel 3D printers.

Usage

On its first run, homebus-dremel needs to know how to find the HomeBus provisioning server.

bundle exec homebus-dremel -b homebus-server-IP-or-domain-name -P homebus-server-port

The port will usually be 80 (its default value).

Once it’s provisioned it stores its provisioning information in .env.provisioning.

homebus-dremel also needs to know:

• URL for Dremel dashboard

Notes
