Thanks! Note that a quirk for this device is not yet upstreamed into HA Core, so even if the firmware exposes new features already, they are not shown in HA as of now (unless you install a custom quirk).

This update was temporarily pulled with this PR (because of the missing model constraints for a conflicting device):

It has now been re-added with this PR (only matching the water valve models, not the shutter relay switch):

You should see it appear in Home Assistant over the next 24 hours. Alternatively, you can restart HA.
As always, feedback on the update is appreciated in this thread (e.g. "works" or "doesn't work", ...).
