OctoEverywhere is an open source project for remotely controlling and monitoring 3D printers. Specifically for Bambu Lab, this project allows remote monitoring and control of their printers when their “Handy App” can’t be used because the printer has been configured to be in “LAN Only mode” and “Developer mode”, which are required in order to use third party slicers, such as Orca Slicer.
In order to work, OctoEverywhere requires a server that can communicate directly with the printer. Usually they recommend setting up a Raspberry PI just for hosting that server, but if you already have a Home Assistant server then it makes much more sense to host OctoEverywhere on it.
This add-on does exactly that, it sets up a OctoEverywhere server container as a Home Assistant add-on. Instructions for installation can be found here:
