Kohler / Rehlko Integration - Oncue replacement

PeteRage · May 6, 2025, 5:37pm

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.

Is there anyway to tell when the machine was last started from the API?

Yes, there are a couple of timestamps the API provides. We can add those as sensors.

Here’s a link to the dataset we get back. Specifically it would be lastRanTimestamp

LastRunTimestamp would be wonderful, but if you’re adding sensors…

lastMaintenanceTimestamp
nextMaintenanceTimestamp
totalRuntimeHours

Thank you!

This one should be in there. May be disabled by default.
