Wolf BWS cooling active state bit

[torsten-rupp]

Your Issue

The Wolf heat pump BWS has an extension cooling device. If cooling is active is indicated in an additional bit in the controller.d_values_rc2 states value starting from https://github.com/csowada/ebus-configuration/blob/master/src/main/resources/commands/common-configuration.json, line 190:

I extended this from

            {"name": "states", "type": "byte", "children": [
                {"name": "state_dhw", "type": "bit", "label": "State DHW active"},
                {"name": "state_hc", "type": "bit", "label": "State heating circuit active"}
            ]},

into this:

            {"name": "states", "type": "byte", "children": [
                {"name": "state_dhw", "type": "bit", "label": "State DHW active"},
                {"name": "state_hc", "type": "bit", "label": "State heating circuit active"},
                {"name": "state_unknown_0x04", "type": "bit", "label": "unknown 0x04"},
                {"name": "state_unknown_0x08", "type": "bit", "label": "unknown 0x08"},
                {"name": "state_unknown_0x10", "type": "bit", "label": "unknown 0x10"},
                {"name": "state_cooling", "type": "bit", "label": "State cooling active"},
                {"name": "state_unknown_0x40", "type": "bit", "label": "unknown 0x40"},
                {"name": "state_unknown_0x80", "type": "bit", "label": "unknown 0x80"}
            ]},

With this settings the cooling state can be linked in the openhab things settings to a item which shows if cooling is active or not.
