Pilight component not loading anymore - "component not found"

Since upgrading to HA 66.1 I cannot load pilight anymore. The config check says “component not found”. The configuration has not changed.

Is there a change in how config files are read or how pilight is run in version 66?

I just downgraded to 65.6 and all is fine again. I have opened a issue on GitHub for this as well.

Working again with latest release 0.67.

I still struggle what the reason was. Release notes suggest that 0.67 only adjusted the default port.
