Hydrotherm X8 no longer accepting turn on and turn off commands

[Brazen00]

Describe the bug
Since updating to HA 2024.9.2 from 2024.8.3, my Hydrotherm X8 has been unable to accept turn_off and turn_on commands.

To Reproduce
I have these as part of automations. However, going to "developer tools">actions and choosing water_heater.turn_off results in Failed to perform the action water_heater.turn_off. Entity water_heater.hot_water_system does not support this service.

Expected behavior
Previously was able to turn the water heater on and off.

Please report to Home Assistant, not here, as the unadvertised change was made on their side:

On looking further, since the comments on the PR seem to suggest they were removing a duplicate service registration with that change, it seems that there was always an ON_OFF feature flag to go with the on/off service, but probably the explicit duplicate made it work without declaring that, so it wasn't detected that the feature flag was missed when adding on/off support to this integration following the same pattern as for climate (which at the time did not have such a flag).

So maybe it can be fixed in this integration.
