SimplyPrint on Home Assistant - run the client on the box that is already on

The SimplyPrint Client add-on runs our printer client directly on your Home Assistant machine, so the hardware you already leave running around the clock is the same hardware that keeps your printers connected. No spare Raspberry Pi per printer, no second thing to maintain.

What this is, and what it is not.

This add-on makes your Home Assistant machine the bridge between your printers and SimplyPrint. That is the whole job.

It does not put your printers into Home Assistant as entities - there are no printer sensors, no temperature or progress values to put on a dashboard, and nothing to drive an automation with. If that is what you came for, it is a separate thing and we have not built it yet: follow suggestion #324.

Full setup guide in our helpdesk →

The add-on uses Home Assistant Ingress, so its interface is served through Home Assistant itself. Turn on Show in sidebar and you get a SimplyPrint entry in your Home Assistant menu. There is no port for you to open, and the client interface only accepts requests coming through Home Assistant.

The add-on is new and still experimental (1.0.0-rc.17). It works and it is ready to use - it just has not been through as many hands as our other install methods. If something looks wrong, open an issue and we will fix it.

Open your Home Assistant instance and add the SimplyPrint add-on repository


What you need

  • Home Assistant OS or a Supervised install. Add-ons need the Supervisor, so Home Assistant Container and Home Assistant Core cannot install this.
  • A 64-bit machine - aarch64 or amd64. A 32-bit Raspberry Pi OS install is not supported.
  • A printer SimplyPrint already supports over a local connection.

Why run it here

  • One box, already on. Your Home Assistant machine is the most reliably powered thing in the house.
  • Backed up with everything else. The add-on participates in Home Assistant backups.
  • Set up from the sidebar. Ingress means the client UI is a panel in Home Assistant, not another address to remember.

  • Runs the SimplyPrint client on the Home Assistant machine you already have powered on
  • One-click repository install through My Home Assistant
  • Appears as a SimplyPrint panel in the Home Assistant sidebar (Ingress)
  • Included in Home Assistant backups
  • Home Assistant OS and Supervised installs, aarch64 and amd64
  • Official add-on repository, maintained by SimplyPrint
  • Does not expose printers as Home Assistant entities - this is the bridge, not a dashboard integration

How to install the SimplyPrint add-on in Home Assistant

1

Check your install type

Add-ons require the Supervisor, so you need Home Assistant OS or a Supervised install on a 64-bit machine. Container and Core installs cannot add this.

2

Add the repository

In Home Assistant go to Settings → Apps (Home Assistant renamed add-ons to apps, so older guides say Add-ons), open the app store, then the three-dot menu, choose Repositories, and paste https://github.com/SimplyPrint/home-assistant-apps.

3

Install SimplyPrint Client

The SimplyPrint Client add-on appears in the store. Open it and click Install. It is an experimental release candidate, so read the warning on the add-on page first.

4

Start it and open the panel

Turn on Start on boot, Watchdog and Show in sidebar, start the add-on, then open SimplyPrint from your Home Assistant menu and follow the setup to connect your printer to your SimplyPrint account.

Frequently asked questions

Is the SimplyPrint Home Assistant add-on ready to use?

Yes. It is published in our official add-on repository and you can install it today. It is still new and experimental (1.0.0-rc.17), so it has not been through as many hands as our other install methods - if you find a bug, tell us and we will fix it.

Will it work on Home Assistant Container or Core?

No. Add-ons are managed by the Home Assistant Supervisor, which only exists on Home Assistant OS and Supervised installs. On Container or Core, run the SimplyPrint client directly on a machine on your network instead.

Which hardware is supported?

64-bit only - aarch64 and amd64. That covers a Raspberry Pi 4 or 5 running 64-bit Home Assistant OS, an Intel NUC, or a generic x86 box. A 32-bit install will not see the add-on.

Do I need to expose a port or set up a tunnel?

No. The add-on uses Home Assistant's Ingress, so its interface is served through Home Assistant itself and the client only accepts requests that arrive that way. Turn on Show in sidebar to get it as a panel in your Home Assistant menu.

Does it get backed up with Home Assistant?

Yes - the add-on is included in Home Assistant's backups, so its configuration travels with the rest of your setup.

Is there a one-click install?

Yes. If you are on a device that can reach your Home Assistant, the Open app store of My Home Assistant button on this page adds our repository for you - then install SimplyPrint Client from the store. The manual route is Settings → Apps (formerly Add-ons) → the app store → three-dot menu → Repositories.

Does this put my printers into Home Assistant as sensors or entities?

No, and this is the most common misunderstanding. The add-on runs the SimplyPrint client on your Home Assistant machine so your printers can reach SimplyPrint - it is a bridge, not a dashboard integration. It creates no entities, so there is no temperature, progress or AMS data to put on a Home Assistant dashboard or drive an automation with. That is a separate piece of work; you can follow and vote for it at suggestion #324.


About SimplyPrint integrations

Integration for SimplyPrint allows for applications to interact with your 3D printers, and your 3D printers to interact with other applications. This allows for endless possibilities, and we strongly believe that your 3D printer should be able to function as an IOT device, working together with any and all applications you can imagine!

This is why the team behind SimplyPrint work to provide official integrations for the most popular platforms, slicer and applications, while also allowing our users to create custom integrations using our API, or for approved third party vendors to create integrations to be used by all SimplyPrint users, using a "Log in with SimplyPrint" method (using the "OAuth2" method).

If you're a developer interested in creating an integration for SimplyPrint, please read our documentation on the subject.

If you're not a developer yourself, but would like to see an integration for a specific application, go check if it's already on our roadmap or suggestion list, and if not, feel free to suggest it!
