How to write value to ElectricalEnergyMeasurement::Attributes::Accuracy::Id (CON-1326)

[svn-matterize]

Trying to write a array value to the attribute ElectricalEnergyMeasurement::Attributes::Accuracy::Id using esp_matter_array

ElectricalEnergyMeasurement::Structs::MeasurementAccuracyRangeStruct::Type energyAccuracyRanges[] = {
		{ .rangeMin = 0,
		  .rangeMax = 1'000'000'000'000'000, // 1 million Mwh
		  .percentMax = chip::MakeOptional(static_cast<chip::Percent100ths>(500)),
		  .percentMin = chip::MakeOptional(static_cast<chip::Percent100ths>(50)) }
	};

	ElectricalEnergyMeasurement::Structs::MeasurementAccuracyStruct::Type accuracy = {
		.measurementType = chip::app::Clusters::detail::MeasurementTypeEnum::kElectricalEnergy,
		.measured = true,
		.minMeasuredValue = 0,
		.maxMeasuredValue = 1'000'000'000'000'000, // 1 million Mwh
		.accuracyRanges = chip::app::DataModel::List<
			const ElectricalEnergyMeasurement::Structs::MeasurementAccuracyRangeStruct::Type>(
			energyAccuracyRanges)
	};
	arr_val = esp_matter_array((uint8_t *)&accuracy, sizeof(arr_val), 1);
	// err = attribute::set_val(attribute, &arr_val);
	err = attribute::update(Endpoint.kPlug, ElectricalEnergyMeasurement::Id,
				ElectricalEnergyMeasurement::Attributes::Accuracy::Id, &arr_val);
	if (err != ESP_OK) {
		ESP_LOGE(TAG, "Updated EnergyAccuracy failed");
	}

Any news about this issue?

@svn-matterize Sorry for the delayed response, you cannot use esp_matter_array for storage because esp-matter doesn’t support array attribute storage. There is API to set Accuracy in the connectedhomeip SDK SetMeasurementAccuracy. You have to use this.

[svn-matterize]

@jadhavrohit924 , attribute storage, are you mentioning (ATTRIBUTE_FLAG_NONVOLATILE) nvs storage? Is it possible to attribute::update/set attribute value using esp_matter_array, if the flag is (ATTRIBUTE_FLAG_NONE)? How to form the struct value to array using esp_matter_array any example.

[jadhavrohit924]

Independent of attribute quality, storage of arrays and structs are not possible using esp-matter because for such attributes there is delegate implementation in the connectedhomeip SDK. But delegate is missing for ElectricalEnergyMeasurement cluster so you have to reach to the SDK to update/set the attribute of this cluster.

Hi there,

Calling this API emits an error CHIP_ERROR_INVALID_ARGUMENT, it seems there's a missing link between EndpointID and emberAfGetClusterServerEndpointIndex() function, as it does not find the corresponding endpoint.

What's really missing?

Queued the function call to post initializing time solves the issue.

@svn-matterize Can you please close the issue if it is resolved?
