The Pi Zero is connected to the Prusa i3 via a microUSB to regular USB cable.

Raspberry Pi Zero monitoring Prusa i3 MK3 through the USB port.

Monitoring only: I don't want to control the printer remotely.

Let's use that instead of attaching stuff to the logic board.

Non-invasive installation: there is a USB port on the Prusa.

That way, I can build automations like: notify me when the printer is almost done or switch off the printer after the print completed. My needs are simple: I want to grab the progress of the current print job and send that to Home Assistant. So I decided to use a Pi Zero to keep track of my 3D prints and send the progress to my Home Assistant installation. It's a super reliable Prusa i3 MK3, but it lacks an internet connection. If you are just starting out, we recommend that you purchase a 700 series controller or a Raspberry Pi module.Many devices in my home have become 'smart' over the last couple of months, with one big exception: my trusty 3D printer.

Z-Wave.Me RaZberry 7 Pro (ZMEERAZBERRY7_PRO or ZMEURAZBERRY7_PRO, 700 series).

Z-Wave.Me RaZberry 7 (ZME_RAZBERRY7, 700 series).

Aeotec Z-Pi 7 Raspberry Pi HAT/Shield (ZWA025, 700 series).

Silicon Labs UZB-7 USB Stick (Silabs SLUSB7000A / SLUSB001A).

Aeotec Z-Stick 7 USB stick (ZWA010) (the EU version is not recommended due to RF performance issues).

Firmware can be upgraded using the below directions: Users should upgrade the firmware on all 700 series controllers to version 7.17.2 or greater. It appears that this bug is largely, if not completely, resolved as of firmware version 7.17.2. At present, all 700 series controllers share the same firmware and are subject to this bug.

Until recently, 700 series Z-Wave Controllers had a bug that could cause the mesh to be flooded on some networks and the controller to become unresponsive.
