PR 175813 fixed a volume step calculation in…
The same theme shows up with Overkiz. iMicknl landed two fixes — PR 175817 for Atlantic heaters missing a regulation mode, and PR 175837 for RollerShutterUno covers that reported "open" even when physically closed, because the device's own state field is unreliable.
