DefaultValueNotFound error when trying to setup Arçelik Gurme Tea Machine

[cemkeylan]

Hello, I am having issues trying to setup my tea machine, this is the error that I am seeing on the logs. I know the tea machine isn't officially supported, but I saw another issue regarding Arçelik Gurme so I decided to post about it. The model of the tea machine is CM9058B, and I can provide any more info that might be necessary.

1. SSH into the server/machine/docker container wherever you're running HA.
2. cd into /YOUR_CONFIG_PATH/custom_components/homewhiz.
3. Open appliance_config.py file with an editor such as vi.
4. Change this line to recipeFormatVersion: str | None so that it doesn't throw an error.
5. Remove the __pycache__ folder.
6. Restart home assistant.

You should now be able to add your device via Cloud. Rest is on you.

Thanks for that fix! Is everything else working fine? I opened a pull request with your change and will merge once you confirm. Thanks ☺️

This little fix only allows us to setup the appliance. I think there's more to take care of before we can say it works. Regardless, this PR is still an improvement and perhaps a determined dev can make it work.

Exactly, the setup works now, but all of the presented entities are unavailable
