    Awesome @Diggerz, that is a huge time and effort-saving feature.

    Last night, I used the "Mass Add Device" feature to add approximately 95 devices (mostly Lights and a few fans) to my AC2, and it seems to be working just great now.

    I think it has significantly less lag than what I had before.

    I've been able to remove the convoluted CGate setup + C-Bus Driver from my HomeBridge system, leaving it to manage the Nuvo Multi-Room Audio system. So that's a win, too.

    BTW, would there be any chance of adding support for HomeKit Thermostats, as I'm now controlling my underfloor heating from the AC2, and it would be great to expose the Thermostat control on HomeKit.

    @kiwi64ajs Im glad it’s getting some use, thanks for the feedback

    I’ll take a look at the HomeKit thermostat over the next week or so and see what I can do.

    Awesome, that would be great.

    I'm mostly only interested in exposing:
    - Temperature current value (CV), an average of 1 or more Dallas 1-Wire sensors that the AC2 can read
    - Temperature setpoint (SP), which the AC2 will compare to the SP, to switch on/off the boiler + zone circ pumps

    My application logic doesn't have any other configurable options, but perhaps there could be an Enable/Disable feature. It only performs heating, so there is no Heating/Cooling mode.

    Updated Version:

    https://www.dropbox.com/scl/fi/sb0g...ey=wht58x0l6lwgqpvh3s62rxguw&st=cdnt1xwz&dl=0

    Opened up all c-bus addresses, and added a conversion for float16 values such as temperature.
    The list of group address will now show groups with a sub group, like the measurement application 0/228/0/x, however be aware some additional filtering still needs to be implemented as currently 0/228/0 may incorrectly show as a group, along with 0/228/0/0, 0/228/0/1, 0/228/0/2 etc. so don’t use the 0/228/0.

    I haven’t tested each device type, so mileage may vary, however types using scale, uint8, bool and foat16 should work.

    Also avoid mapping the same group to differing types, as it can cause the app to lock up.

    Amazing, better than the KNX Implementation

    Yes, this is awesome, many thanks.
    Hopefully, I can now add my three thermostats and remove the Home-Bridge kluge I had added previously.

    Fantasic, love your work! With the update, I can now open my garage using Apple Home... Can even open the garage door on approach using location based automation. You could get a job at Clipsal / Schneider.
