Additional context

[fedefreue]

From my research, it seems that this is due to the breaking changes to the Grocy API in v4.0. Not sure if the fix will here or in pygrocy, but from what I understood it has to do with changes to the quantity units.

[squirtbrnr]

I successfully reverted and restored my Grocy install back to v3.3.2 and can confirm the integration is working again.

[unresolved-contradictions]

The issue seems to be with pygrocy and the breaking changes in the Grocy API. I got it working again by changing the 'requirements' in 'manifest.json' from "requirements": ["pygrocy==1.5.0"], to "requirements": ["git+https://github.com/fedefreue/pygrocy.git@develop#pygrocy"],

The above is a branch of pygrocy removing the offending issues.

[fedefreue]

That's great! I didn't realize I could cherry pick my branch to fix it in the interim... Seems like a good fix until it gets merged into the master for pygrocy.

[MelvinLoos]

Either edit the requirements or opt into the experimental releases. I did the latter and it all seems to work as well although I did have to (re)enable all sensors which seemed to have been disabled. Not sure if that was my own doing though.

[squirtbrnr]

I was using the Grocy custom component v4.10.0 (enable beta in HACS) which uses the pygrocy v1.5.0 library and it was not working for me and still displayed the error I posted above.

Have you tried the fix I mentioned above, editing the 'requirements' in 'manifest.json'? I am running the same versions as you and this fixed the problem.

[fedefreue]

The way it breaks down is as follows:

• Grocy < v4.0: No issue but requires latest version of custom component (fixes for HASS 2023.08)
• Grocy >= v4.0: Needs @sailseaplymouth 's fix to manifes.json above, since the issue is in pygrocy and not in the custom HASS component

I already submitted a pull request to pygrocy so I think it's a waiting game until that gets updated and then subsequently updating the requirement here so that the fix carries over.

This question most closely matched my problem, but the solution must have changed. I have Grocy add on ver 4.0.3 and my manifest.json references pygrocy 2.0. I changed it to the code above -"git+https://github.com/fedefreue/pygrocy.git@develop#pygrocy" - and restarted HA (of course) but all sensors remain unavailable in the integration. What am I doing wrong? - because it always ends up being that LOL. If it helps, I had Grocy integration installed before and deleted it because of this same problem. The add on has been reliable (so far)

[fedefreue]

I'm running the latest stable version for both the HA add-on and for Grocy and am not experiencing this - could be due to something different? Want to share your logs - I can take a look

Not sure if this is the log info you need. I got it after enabling "debug logging" in the integration:

I changed log level in the yaml for the add on to debug and get:

From what I can see above, it seems it's failing when updating the add-on? What's challenging is I can't reproduce (and am also on the latest for both)

@Caddyman68 I appreciate finding the apparently single other person in the world with the same niche problem as me!

Found a solution that fixed it for me, and might help you -- update pygrocy to 2.1.0. This fixes it for shopping lists and stock, but doesn't seem like for meal plans.

I found SebRut/pygrocy#272 in 2.1.0, looks like one of the last changes in pygrocy before being archived was fixing exactly this.

Edit: PR up #311
