I finally got my credentials; linked the dev keys to my account and I get the following errors:

note, after restart I get:

2019-05-30 00:26:25 WARNING (MainThread) [homeassistant.helpers.service] Unable to find services.yaml for the miele integration

and after a 2nd restart I now have my tumble dryer entry loaded....so it works - but seem to require multiple restarts ?
