Run the SimplyPrint Client as a Home Assistant add-on

If you already run Home Assistant, you already own an always-on machine. This add-on lets that same machine run the SimplyPrint Client, so it becomes the bridge between your printers and SimplyPrint. No spare Raspberry Pi per printer, and nothing extra to keep updated.


This add-on does not put your printers into Home Assistant. It creates no devices, no entities and no sensors. There is nothing to place on a Home Assistant dashboard and nothing to trigger an automation with. Read the first section before you install.


What this guide covers


What this add-on is, and what it is not

Two different things get asked for under the name "Home Assistant integration", and they solve opposite problems:


  1. Printers appearing inside Home Assistant as entities, so you can build dashboards and automations from nozzle temperature, progress, filament and so on.
  2. The SimplyPrint Client running inside Home Assistant, so your Home Assistant box is the bridge that connects your printers to SimplyPrint.


This add-on is number 2, and only number 2. It runs our client software on your Home Assistant machine. Your printers then appear in SimplyPrint, exactly as they would if the client were running on a Raspberry Pi instead.


If you came here for number 1, we have not built it. You can follow and vote for it on our suggestion board at suggestion #324, which is where that request lives.


What you need

Add-ons are managed by the Home Assistant Supervisor. Home Assistant Container and Home Assistant Core do not have a Supervisor, so they cannot install any add-on, including this one.


  • Home Assistant OS or a Supervised install.
  • A 64-bit machine, either aarch64 or amd64. A 32-bit Raspberry Pi OS install will not see the add-on in the store.
  • Your printer on the same network as Home Assistant.
  • A printer that SimplyPrint supports over a local connection.


On Container or Core, install the SimplyPrint Client the normal way on any machine on your network instead. See Connect your printers with the SimplyPrint Client for that route.


Add the repository

If you are reading this on a device that can reach your Home Assistant, use the button. It fills in the repository address for you.



That opens your own Home Assistant, goes to the app store, and offers to add our repository. Accept it, then carry on below.


To do it by hand instead:


  1. In Home Assistant, go to Settings, then Apps. Home Assistant renamed add-ons to apps, so older guides call this Add-ons.
  2. Open the app store, then the three-dot menu in the top right, and choose Repositories.
  3. Paste https://github.com/SimplyPrint/home-assistant-apps and click Add.
  4. Close the dialog. The store reloads with a new SimplyPrint section.


Install and start it

  1. Find SimplyPrint Client in the store and open it.
  2. Click Install. The first install pulls the image, so give it a minute.
  3. Turn on Start on boot and Watchdog so the client comes back by itself after a reboot.
  4. Turn on Show in sidebar if you want the SimplyPrint panel in your Home Assistant menu, which is the easiest way to reach it.
  5. Click Start.


Open it from the Home Assistant sidebar

The add-on uses Home Assistant Ingress, so its interface is served through Home Assistant itself rather than on its own address. With Show in sidebar enabled you get a SimplyPrint entry in your Home Assistant menu.


That means there is no port for you to open, and the client interface only accepts requests coming through Home Assistant.


Open that panel and follow the setup inside it to link each printer to your SimplyPrint account. From that point on your printers behave like any other SimplyPrint printer.


Your setup is included in Home Assistant's own backups, so the add-on and its printer configuration travel with the rest of your system.


It is new, and still experimental

The add-on works and is ready for you to use. It has simply had fewer users than our other install methods, so there is more chance of you being the first to meet a given bug.


If something looks wrong, open an issue on GitHub with what you did and what happened. That is the fastest route to a fix, and it goes straight to the people who maintain the add-on.


If you would rather be on the best-travelled path today, run the client on a Raspberry Pi or in Docker instead. Everything else about your SimplyPrint account is identical either way.


Frequently asked questions

Quick answers to the things people ask most about the add-on.


Can I see printer temperature or progress in Home Assistant?

No. The add-on creates no entities, so there is nothing for a dashboard card or an automation to read. See What this add-on is, and what it is not above, and suggestion #324.


Can I start a print from a Home Assistant automation?

No, for the same reason. Start prints from SimplyPrint, in the browser or the mobile app.


Does it work on Home Assistant Container or Core?

No. Those have no Supervisor, so they cannot install add-ons at all. Run the client on another machine on your network instead.


Will a 32-bit Raspberry Pi OS install work?

No. The add-on is built for aarch64 and amd64 only, and a 32-bit install will not list it in the store.


Do I still need a Raspberry Pi per printer?

No, that is the point of running it here. One Home Assistant machine can bridge the printers on your network.


Is it included in Home Assistant backups?

Yes. Restoring a Home Assistant backup restores the add-on and its printer configuration with it.
