Unable to dim light on Google Home App with Matter bridge app

lijie — Sat, 04 Mar 2023 11:05:33 GMT

Based on the examples/bridge-app reference using the v1.0.0.2 tag in the Matter SDK, I have added a dimmable light using the OnOff Cluster and LevelControl Cluster. It works fine in the Apple Home app, but in the Google Home app, I can only turn it on or off. The dimmable button is disabled by default, and the dimming feature does not work without sending any interaction commands.

PS:
Matter SDK Version: v1.0.0.2
Google Home App Version: 2.65.24.1-dogfood
Google Nest Display Version: 1.56.324896

Thanks for bringing this up. Project Chip on GitHub mentions only OnOff cluster in readme file. Check with developers if it’s meant to also support LevelControl cluster. Looking at history of commits it might still be under development. If you continue to experience issues please create a ticket on GitHub.

@lijie have you tested the dimmable light with alexa. As I'm facing the issue with alexa .

@Harry_p Yep, I just tested Alexa. Everything is fine.

Is there anything that you have changed in the configuration as when I change the brightness values, the callbacks are not called.

These are the level configurations made:

DECLARE_DYNAMIC_CLUSTER_LIST_BEGIN(bridgedLightClusters)

DECLARE_DYNAMIC_CLUSTER(OnOff::Id, onOffAttrs, onOffIncomingCommands, nullptr),

DECLARE_DYNAMIC_CLUSTER(Descriptor::Id, descriptorAttrs, nullptr, nullptr),

DECLARE_DYNAMIC_CLUSTER(BridgedDeviceBasic::Id, bridgedDeviceBasicAttrs, nullptr,

nullptr) DECLARE_DYNAMIC_CLUSTER_LIST_END;

// Declare Bridged Light endpoint

DECLARE_DYNAMIC_ENDPOINT(bridgedLightEndpoint, bridgedLightClusters);

DataVersion gLight1DataVersions[ArraySize(bridgedLightClusters)];

// Declare Dimmable Control cluster attributes

DECLARE_DYNAMIC_ATTRIBUTE_LIST_BEGIN(dimmableControlAttrs)

DECLARE_DYNAMIC_ATTRIBUTE(ZCL_ON_OFF_ATTRIBUTE_ID, BOOLEAN, 1, 0),

DECLARE_DYNAMIC_ATTRIBUTE(ZCL_CURRENT_LEVEL_ATTRIBUTE_ID , INT8U, 1, 0),

DECLARE_DYNAMIC_ATTRIBUTE(ZCL_LEVEL_CONTROL_REMAINING_TIME_ATTRIBUTE_ID , INT16U, 2,ZAP_ATTRIBUTE_MASK(WRITABLE) | ZAP_ATTRIBUTE_MASK(NULLABLE)),

DECLARE_DYNAMIC_ATTRIBUTE_LIST_END();

The change callback used:

void HandleDeviceStatusChangedDim(Device * dev, Device::Changed_t itemChangedMask)

{

if (itemChangedMask & Device::kChanged_Reachable)

{

ScheduleReportingCallback(dev, BridgedDeviceBasic::Id, BridgedDeviceBasic::Attributes::Reachable::Id);

}

if (itemChangedMask & Device::kChanged_State)

{

printf("the level chnage callback \n ");

ScheduleReportingCallback(dev, LevelControl::Id, LevelControl::Attributes::CurrentLevel::Id);

// MatterReportingAttributeChangeCallback(dev->GetEndpointId(), LevelControl::Id, ZCL_CURRENT_LEVEL_ATTRIBUTE_ID,

// ZCL_BOOLEAN_ATTRIBUTE_TYPE,NULL);

}

if (itemChangedMask & Device::kChanged_Name)

{

ScheduleReportingCallback(dev, BridgedDeviceBasic::Id, BridgedDeviceBasic::Attributes::NodeLabel::Id);

}

@Harry_p You need to reference the 'Dimmable Light' device type in order to implement all the mandatory clusters.

ID Cluster Client/Server Quality Conformance

0x0003	Identify	Server	M
0x0004	Groups	Server	M
0x0005	Scenes	Server	M
0x0006	On/Off	Server	M
0x0008	Level Control	Server	M
0x0406	Occupancy Sensing	Client	O

I gave up this micro implementation instead of using the examples at https://github.com/espressif/esp-matter/tree/main/examples/zigbee_bridge."

@lijie As I'm adding the non-zigbee devices I have choosen bridge-app example. I can see the device as dimmer in alexa, but the thing is when changing the levels the callbacks are not active any idea about this issue.
