Are these changes backwards compatible?

[cweitkamp]

@cpmeister A comparison:

One thing we will lose is the "Lighting" tag form some channel types which imo is not relevant anymore. Semantics are using the "Light" tag.

The more detailed descriptions for the channels types can be backported to OHC.

[cweitkamp]

public static final ChannelType SYSTEM_COLOR = ChannelTypeBuilder
        .state(new ChannelTypeUID(BINDING_ID, "color"), "Color", "Color")
        .withDescription("Controls the color of the light").withCategory("ColorLight").build();

[cweitkamp]

public static final ChannelType SYSTEM_POWER = ChannelTypeBuilder
        .state(new ChannelTypeUID(BINDING_ID, "power"), "Power", "Switch")
        .withDescription("Device is operable when channel has state ON").withCategory("Switch").build();

[cweitkamp]

public static final ChannelType SYSTEM_COLOR_TEMPERATURE = ChannelTypeBuilder
        .state(new ChannelTypeUID(BINDING_ID, "color-temperature"), "Color Temperature", "Dimmer")
        .withDescription("Controls the color temperature of the light").withCategory("ColorLight")
        .withStateDescriptionFragment(StateDescriptionFragmentBuilder.create().withMinimum(BigDecimal.ZERO)
                .withMaximum(new BigDecimal(100)).withPattern("%d").build())
        .build();

public static final ChannelType SYSTEM_BRIGHTNESS = ChannelTypeBuilder
        .state(new ChannelTypeUID(BINDING_ID, "brightness"), "Brightness", "Dimmer")
        .withDescription("Controls the brightness and switches the light on and off").withCategory("Light")
        .withStateDescriptionFragment(StateDescriptionFragmentBuilder.create().withMinimum(BigDecimal.ZERO)
                .withMaximum(new BigDecimal(100)).withPattern("%d %%").build())
        .build();

Hi,
I recently switched to M1 and I lost all my thing channels for hue lamps except the alarm/loop.
Could this be related to this change? The items seem still to be linked and interaction is possible (I can control lights via OH), but the channels are "invisible".

[cweitkamp]

Yes, it is. For managed Things the Channel Type is stored in JSON storage and will not be changed accordingly. To solve your issue you have to delete and recreate your Thing.

[BobMiles]

Thank you very much for the quick answer!
