Detail Informations

Hello!

Is it possible to add a support for a charging station at least as a Electricity Meter?

[tassy-h]

Hi pratsenka,
Charging Station and Electricity Meter are not included in the standard HAP services, so they are not implemented in this plugin at the moment.
It is technically possible to implement them as custom, non‑standard services outside of the official HAP specification, but in that case they will not be usable from Apple’s Home app.
However, third‑party Home apps such as Eve appear to support custom service implementations, so supporting them is not impossible.

[pratsenka]

i saw some electricity meters are marked as compatible devices and thought i can implement a control of my station state via node-red scenarios. but as far as i catch it is too difficult to do it this way

[tassy-h]

I saw your comment saying that some electricity meters are marked as compatible devices.

Could you tell me more about this?
Where did you see the “compatible devices” information?
It’s possible that electricity meters might actually be supported in Apple’s Home app and I’m simply not aware of it.

As mentioned earlier, this plugin does not implement Charging Stations or Electricity Meters because they are not part of the standard HAP services.
However, the plugin does include features similar to electricity‑meter functionality for Switch / Outlet devices.
These values are not shown in Apple’s Home app, but they are visible in third‑party apps such as Eve.

So, if your device can be recognized as a Switch or Outlet, you may be able to achieve what you want.
You can use the plugin’s deviceOverrides setting to force the device to be treated as a Switch or Outlet.

see ADVANCED_OPTIONS

It would probably look something like this:

"deviceOverrides": [
    {
        "id": "your-device-id",
        "category": "kg",
        "unbridged": false,

            {
                "code": "charge_energy_once",
                "newCode": "add_ele",
                "type": "Integer",
                "hidden": false,

			      "scale": 3,
			      "step": 1
			    }
            },
            {
                "code": "power_total",
                "newCode": "cur_power",
                "type": "Integer",
                "hidden": false,
                "property": {
			      "unit": "kW",
			      "min": 0,
			      "max": 99999999,
			      "scale": 3,
			      "step": 1
			    }
            },
        ]
    }
]

[pratsenka]

there is a device coded zndb at a page https://github.com/homebridge-plugins/homebridge-tuya/blob/latest/SUPPORTED_DEVICES.md
i thought it suits better if i need just metering

[tassy-h]

Thank you for the information.
It’s true that the page lists zndb, but since there is no check mark in the Supported column, unfortunately it means it is not actually supported.
