Trying to start helping

[spirann]

Hello,

I'd like to help the project, so I've implemented the water central meter
you can see it here : spirann@cfd50d8

but when I restart home assistant I got this in the logs :

2024-10-02 16:17:36.512 DEBUG (Thread-3 (_thread_main)) [custom_components.nhc2.nhccoco.coco] Added device f8e2810d-0974-4222-bd7f-2e5996dcec36 of class CocoLightAction

Why is it skipping my watercentralmeters ?

See

'CocoWaterCentralmeter',

To my knowledge the CocoWaterCentralmeter does not expose any useful properties. Unless there is an update?

It should contain the the water volume. I'm trying to get my consommation into HA
I've implemented
@property def water_volume(self) -> float: return to_float_or_none(self.extract_property_value(PROPERTY_WATER_VOLUME))

based on the received device list:
{'Uuid': 'd60f1fff-05ff-48ff-90ff-b2e7bb93a5ff', 'Identifier': 'ed36adff-a5ff-48ff-bfff-86fba30ef6ff', 'Model': 'water', 'Online': 'True', 'Name': 'Boiler', 'Technology': 'nikohomecontrol', 'Type': 'centralmeter', 'Traits': [{'Channel': '0'}, {'MacAddress': '00200FAFF'}], 'Parameters': [{'LocationId': '0ee306ff-30ff-42ff-a4ff-89fec29dfcff'}, {'Segment': 'Subsegment'}, {'PulsesPerUnit': '1000'}, {'LocationIcon': 'cold-storage-room'}, {'Flow': 'Consumer'}, {'ShortName': 'Boiler'}, {'LocationName': 'Annexe'}], 'Properties': [{'WaterVolume': ''}], 'PropertyDefinitions': [{'WaterVolume': {'HasStatus': 'false', 'CanControl': 'false', 'Description': 'Range(0.0000,3.2512,0.0001)'}}]}

Why should it not contains any useful properties ? Water Volume stays empty ?I though it will be refreshed with real value.
Why exposing it via api if not to be exploited ?

Aha in previous versions these propers were not exposed (to my knowledge).
In that case you will need to remove this ignore class:

niko-home-control-II/custom_components/nhc2/nhccoco/coco.py

Thanks to you, I have fixed my implementation. But like you thought, in the Niko documentation it's described as not implemented and the value stays empty : 'Properties': [{'WaterVolume': ''}]`.
But it was a good training, I just need to wait for Niko to insert the value....
