@mkmer
Can you tell us which device models this applies to?

[mkmer]

@lboue - I don't under stand the question: which device models? It (the API) supports washer/dryer, air conditioners, and ovens. Maybe abmantis knows models?
I'm adding the diagnostics to dump all devices supported by the whirlpool integration. I only noticed today, when trying to debug login issues, that we didn't have diagnostics in the integration.

Thanks for the explanation.
