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 some missing model constraints for the other valve model):

It has now been re-added with this PR:

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", ...).
