No longer works

[Scales82]

This integration no longer works with my brewfather. Tried recreating it with a new API key and no luck. Stuck on retrying setup constantly.

[MvdDonk]

@Scales82 Sorry to hear the integration setup is failing. I have just tested it myself and both an existing integration and adding a new one seems to work without issues. Which version of Home Assistant are you running? Was the integration working before? Did it perhaps stopped working after a Home Assistant upgrade?

Maybe there is some information in the logs: https://my.home-assistant.io/redirect/logs/

Any more information can be helpfull, thanks!

I have the same issue. Stuck on initializing after initial setup. I just installed it. Here's the log:

I'm getting the same errors. Home Assistant version: 2023.9.3 (official docker image) Python Version: 3.11.5

I finally found some time to look into the errors. Probably it has to do with some specific json response you are getting which I'm unable to reproduce. So for now I've added extra logging so hopefully I can reproduce the error and fix the problems. I've create a new version of the Brewfather integration so please update. If you can enable debug logging for the Brewfather integration, restart home assistant, disable debug logging and sent me the file I might be able to get more info on the issue.

Please make sure you see some message like the following in the log file:

DEBUG (MainThread) [custom_components.brewfather.connection] get_batches https://api.brewfather.app/v2/batches/?status=Fermenting (False)
DEBUG (MainThread) [custom_components.brewfather.connection] get_batch https://api.brewfather.app/v2/batches/dpMXZzseP8PqbjG2VJjkC4p3LQwZ6S?include=recipe.fermentation,notes,measuredOg (False)
DEBUG (MainThread) [custom_components.brewfather.connection] get_readings https://api.brewfather.app/v2/batches/dpMXZzseP8PqbjG2VJjkC4p3LQwZ6S/readings (False)

If the log file does not have these lines in it you can try adding a new connection/running the setup:

[psychopenguin]

Hi! Thanks for the update. I've tried with the new version and also noticed that you update to API v2. :)

But it still not working. Here are the debug logs:

[MvdDonk]

@psychopenguin thanks, that was very useful! It appears the Brewfather api returned a translated value for the word "Batch", which is "Lote" in Italian I assume? ;) My code wasn't expecting that to happen and I wasn't having the issue because my Brewfather is running in English.

Anyway, I released a new version (v1.1.2) which hopefully fixes your issue!

[MvdDonk]

@jeroenterheerdt can you update the Brewfather integration to the latest version (v1.1.2) and test again? If it's still not working please send me the logs.

[psychopenguin]

It appears the Brewfather api returned a translated value for the word "Batch", which is "Lote" in Italian I assume? ;)

Actually, it's Portuguese :)

Well, I tried with v1.1.2 (and also the main branch) and it still doesn't work. I also put my BrewFather settings in English and create a new batch, without success. the logs are almost the same from previous version:

Hey hey @MvdDonk

I finally made it work. I found the issue was the wrong type for step_time parameter, as my recipes use some steps with decimal value, for example I put bottle as 0.1day. So I changed the type from int to float. I've opened a pull request with the fix.

Let me know when you merge and tag it then I can switch my HACS configuration to use your repo again. :)

@jeroenterheerdt can you also see if this fix your issue?

Thanks!

[MvdDonk]

Hi @psychopenguin , thanks for helping with the issue. I actually just published a new version (v1.1.4) which contains the same fix (and other stuff) but I rewrote quite a bit of code. Can you try the latest version and let me know if that one works? I have added the translations, thanks for your work!!

[psychopenguin]

hi @MvdDonk thanks to accept the translation :)

~i've tried this new version, but despite logs says the data was fetched successfully, sensors aren't being updated.~

Never mind - I just noticed in the logs the json response was empty. I though that I had an active batch - it was showing on UI (so I guess it was a browser cache issue), but when I query the API with curl it was empty. I've added a new batch and it's working now :D

Thanks for the effort!

[MvdDonk]

Closing issue due to no response
