PrusaLink integration does not work with the current version PrusaLink 0.7.0

[larsschweier]

The problem

Have intalled PrusaLink 0.7.0 on my Raspberry Pi3 on PrusaMKS3+, unfortunately the integration fails with the error "Only PrusaLink API v2 is supported".

PrusaLink does display:

API 0.9.0-legacy
Hostname prusalink
Firmware 3.12.2-5713
Server 0.7.0
Text PrusaLink 0.7.0
SDK 0.7.0
Frontend 3.12.0

Prusalink 0.7.0 was released 19th of may 2023. It seems the integration into homeassistant hasnt picked up the latest changes in the API's since Prusalink 0.6.0

[aderusha]

Discussion on the forums here: https://community.home-assistant.io/t/prusa-3d-printers-support/550070

I had created an issue previously that was closed by way of changing the documentation to say it only supports the mini: #86230

That documentation change was reverted to remove that text without any change to the code: home-assistant/home-assistant.io#27922

I don't have a mk4 to test with, but the version they claim works with the mk4 does not work with my XL, and there have been no substantial code changes to the integration so I'm wondering how or if it actually supports the mk4 when it didn't before.

[tomber71]

Just removed OctoPrint and installed PrusaLink and found out PrusaLink 0.7.0 is NOT supported. Failing with error: "Only PrusaLink API v2 is supported". What a bummer :-(

[aderusha]

I have to walk back the "does not work with my XL", turns out that was a "me" problem and it does work fine w/ the XL as delivered. I've updated the PrusaLink software running my mk3 to the latest dev build from the repo and the behavior is still the same.

So, this integration supports the embedded PrusaLink but not the standalone PrusaLink project.

[tomber71]

Looks like API version is 0.9.0-legacy.

Mine doesn't work on my mk4 either.

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.
Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍
This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

[aderusha]

Replying here to keep the bot from marking this issue as stale. This is still a problem for systems running the PrusaLink software. Further, several attempts to fix it have been met with a "nope not good enough" which means instead of an OK solution we have absolutely no solution that works at all.

Looks like the Prusa Link for MK3.x will get an update to the new API with the next release: prusa3d/Prusa-Link@02e6a82

[Atarinside]

Hi,

I've updated my MK3s (firmware 3.13.2-7080 + PrusaLink 0.7.2 on a RPI 2 w), i can't login anymore to the printer within HA.
it previously worked for some time when i was with Prusalink 0.6, recently i had a "migration error" message so i decided to update everything and delete/reinstall the integration.
Since then i can't reinstall the integration, it keeps asking for an unknown user/password : I tried the user/password of prusalink and also with the api key, nothing is working.

With a browser:

http://[Myip]/api/printer :
{"temperature": {"tool0": {"actual": 22.2, "target": 0.0}, "bed": {"actual": 23.3, "target": 0.0}}, "sd": {"ready": true}, "state": {"text": "Operational", "flags": {"operational": true, "paused": false, "printing": false, "cancelling": false, "pausing": false, "sdReady": true, "error": false, "ready": true, "closedOrError": false, "finished": false, "prepared": false, "link_state": "IDLE"}}, "telemetry": {"temp-bed": 23.3, "temp-nozzle": 22.2, "material": " - ", "z-height": 0.15, "print-speed": 100, "axis_x": 0.0, "axis_y": 0.0, "axis_z": 0.15}, "storage": {"local": {"free_space": 28248391680, "total_space": 31132934144}, "sd_card": null}}

Same for http://[Myip]/api/version
{"api": "0.9.0-legacy", "server": "0.7.2", "original": "PrusaLink I3MK3S", "text": "PrusaLink 0.7.2", "firmware": "3.13.2-7080", "sdk": "0.7.1", "capabilities": {"upload-by-put": true}, "hostname": "prusa"}

What am i doing wrong ?
Thanks.

What am i doing wrong ?

Right now, nothing. The PrusaLink integration still doesn't work with the software called PrusaLink. It looks like the next release of PrusaLink is going to change the API version response string so that could maybe work? We'll see when that's released I guess.

[Skaronator]

Additionally, the digest implementation is currently broken (but a PR is open) home-assistant-libs/pyprusalink#77

[Atarinside]

Ok thanks, wait and see then...But why not using the API key instead (like a lot of other integrations in HA) ?
Because you can generate an API key in Prusalink (in the settings).

[Skaronator]

API key is considered deprecated and the HTTP Digest Auth is the way to move forward. The SL1(s) printer doesn't even have the old API key auth. On Mini/MK4/XL the API Key and Digest Auth Password are equal. Probably the same for Raspi PrusaLink as well. So not a big change for the enduser.

[the-ress]

Probably the same for Raspi PrusaLink as well.

On Raspi PrusaLink they're different. (Just a nitpick, it doesn't really matter since MK3 isn't officially supported yet.)
