Hi,

I see this will become a problem in the not so distant future and thought I should bring it to your intention.

No 'version' key in the manifest file for custom integration 'picnic'. As of Home Assistant 2021.6, this integration will no longer be loaded. Please report this to the maintainer of 'picnic'

a temp solution is to manually add "version": "0.0.1" to the /config/custom_components/picnic/manifest.json file.
