2021-05-27 10:05:53 ERROR (MainThread) [homeassistant.loader] No 'version' key in the manifest file for custom integration 'wyzesense'. As of Home Assistant 2021.6, this integration will no longer be loaded. Please report this to the maintainer of 'wyzesense'
This is with core-2021.6.0b0
I reverted back to this version to get it working again: core-2021.5.5
The version was added to the manifest a little while back as quick fix to prevent it from stopping working with no reason. Update the integration and it should resolve it.
