In Home Assistant 2025.5.0 the Oncue integration is discontinued and being replaced with the Rehlko (aka Kohler Energy Management) integration. This is being done because Kohler is discontinuing the OnCue app and api.kohler.com and replacing it with the Kohler Energy Management app and api.rehlko.com
Most of the existing data is available as well as some new data that wasn’t available.
Post your question and comments and I’ll do my best to answer them and update the new integration.
