Drain sensor error not revealed in Home Assistant

[sharwell]

Kumo Cloud is showing the following error:

Code: 2502

Your unit's drain sensor or float switch has tripped. Let a technician know about this.

I didn't see the same error anywhere in Home Assistant. Please let me know if you need me to manually invoke any APIs locally to better determine how this could be integrated in the future.

Please keep in mind that our use of the Kumo API is reverse-engineered based on observing the communications between the app and an indoor unit. So someone who's seeing this (or a similar error) would have to investigate.

There is a flag for "filterDirty" in the logs we've got, and that is exposed as an attribute in HA. But nothing I have talks about drain, though "floatSwitchWet" is mentioned in traces from the KumoCloud service.

If you'd like to poke around, there are instructions on using pykumo interactively over in that repo.

Yep, I suspected this. I vacuumed out the line today so the active alert is cleared, but I do still see it listed under historical alerts.
