Homekit (addon 2.5.5) lightbulb brightness - dimmer not working

I use Plugin " Homebridge Openhab2 Complete"
mine setting as

{
    "platform": "openHAB2-Complete",
    "host": "http://192.168.000.000",
    "port": "8080",
    "accessories": [
        {
            "type": "group",
            "name": "OrnamentCabine",
            "model": "Sonoff S2",
            "items": [
                {
                    "type": "light",
                    "items": [
                        {
                            "name": "OC Main Light",
                            "item": "Light_LivingRoom_OrnamentCabinetMainL_SW"
                        },
                        {
                            "name": "OC Led Strip",
                            "item": "Light_LivingRoom_OrnamentCabinetSubL_SW"
                        }
                    ]
                }
            ]
        }
    ]
}

nice done. and yes, it is multiple services linked to one accessory. this is currently not supported by homekit binding.
i would love to have it as well but personally i dont think i will get time to implement this in the next 2 months. but maybe somebody else will do it.

in fact it’s very easy to install homebridge, especially now have "Homebridge Config UI X ", you can do all the setting under web page, you can finish all setting wihtin 10 mins.

yes, homebridge was initial setup but im not a big fan of bridges. less bridges is better - better performance and less maintenance. so, trying to get homekit binding at same level as homebridge.

me too~, same as mime
