Have you been able to identify the cause of this error? |
|
No |
|
@JoseAntonioMG Power can be easily calculated using voltage and current, right? |
|
@jadhavrohit924, i get the power from the PZEM004T, I also get the watts/hour. Have you seen the code I wrote above in the app_driver.cpp?
I seen the #1092 comment and it does not solve the problem since electrical_energy_measurement does not have a delegate. also i seen the #1075 comment, where you mention this problem but I do not know how it is implemented with SDK connectedhomeip. Thanks for your interest. |
For updating energy I've a working code: on global: #include <app/clusters/electrical-energy-measurement-server/electrical-energy-measurement-server.h>
chip::app::Clusters::ElectricalEnergyMeasurement::ElectricalEnergyMeasurementAttrAccess* energyMeasurementAccess;Initializing the cluster: esp_matter::cluster::electrical_energy_measurement::config_t energy_measurement_config;
auto cumulative_energy_feature = esp_matter::cluster::electrical_energy_measurement::feature::cumulative_energy::get_id();
auto exported_energy_feature = esp_matter::cluster::electrical_energy_measurement::feature::exported_energy::get_id();
auto relay_energy_measurement_cluster = esp_matter::cluster::electrical_energy_measurement::create(relay_endpoint, &energy_measurement_config, esp_matter::CLUSTER_FLAG_SERVER, cumulative_energy_feature | exported_energy_feature);
auto mask = chip::BitMask<chip::app::Clusters::ElectricalEnergyMeasurement::Feature>(chip::app::Clusters::ElectricalEnergyMeasurement::Feature::kCumulativeEnergy, chip::app::Clusters::ElectricalEnergyMeasurement::Feature::kExportedEnergy);
auto optionalmask = chip::BitMask<chip::app::Clusters::ElectricalEnergyMeasurement::OptionalAttributes>(chip::app::Clusters::ElectricalEnergyMeasurement::OptionalAttributes::kOptionalAttributeCumulativeEnergyReset);
energyMeasurementAccess = new chip::app::Clusters::ElectricalEnergyMeasurement::ElectricalEnergyMeasurementAttrAccess(mask,optionalmask);
// energyMeasurementAccess.mEndpointId=relay_endpoint_id;
auto initerr = energyMeasurementAccess->Init();
if (chip::ChipError::IsSuccess(initerr) == false) {
logger.E("energyMeasurementAccess->Init() ERR %u %u", initerr.GetRange(), initerr.GetValue());
}
chip::app::Clusters::ElectricalEnergyMeasurement::Structs::MeasurementAccuracyStruct::Type measurementAccuracy;
chip::app::Clusters::ElectricalEnergyMeasurement::Structs::MeasurementAccuracyRangeStruct::Type measurementAccuracyRange;
measurementAccuracy.measured = true;
measurementAccuracy.measurementType = chip::app::Clusters::detail::MeasurementTypeEnum::kElectricalEnergy;
measurementAccuracy.maxMeasuredValue = max_energy;
measurementAccuracy.minMeasuredValue = 0;
measurementAccuracyRange.rangeMax = max_energy;
measurementAccuracyRange.rangeMin = 0;
measurementAccuracyRange.percentMax.SetValue(energy_max_accuracy);
measurementAccuracyRange.percentMin.SetValue(energy_min_accuracy);
measurementAccuracyRange.percentTypical.SetValue(energy_typ_accuracy);
// measurementAccuracyRange.fixedMax.SetValue(187650443764698);
// measurementAccuracyRange.fixedMin.SetValue(187650443764696);
// measurementAccuracyRange.fixedTypical.SetValue(0);
measurementAccuracy.accuracyRanges = {measurementAccuracyRange};
// chip::app::Clusters::ElectricalEnergyMeasurement::
auto err = chip::app::Clusters::ElectricalEnergyMeasurement::SetMeasurementAccuracy(relay_endpoint_id, measurementAccuracy);
if (chip::ChipError::IsSuccess(err) == false) {
logger.E("SetMeasurementAccuracy ERR %u %u", err.GetRange(), err.GetValue()); // Change to log_e or your own logger
}Then when an energy value is ready: chip::app::Clusters::ElectricalEnergyMeasurement::Structs::EnergyMeasurementStruct::Type measurement;
measurement.startTimestamp.SetValue(energy_start_time); // Change to your marked start EPOCH time of energy
measurement.endTimestamp.SetValue(getEPOCHTime()); // Change to your own API to get EPOCH time (Or use systime APIs)
measurement.energy = value;
chip::DeviceLayer::StackLock lock;
auto success = chip::app::Clusters::ElectricalEnergyMeasurement::NotifyCumulativeEnergyMeasured(endpoint_id, {}, chip::Optional<chip::app::Clusters::ElectricalEnergyMeasurement::Structs::EnergyMeasurementStruct::Type> (measurement));
logger.I("NotifyCumulativeEnergyMeasured() -> %u", success);
Note that I have only one issue not solved for now: Energy accuracy, which reads out in chip-tool empty: |
|
Update: I've just called to set measurement accuracy after the initialization process, and it worked. Just ensure the Accuracy Ranges be a static or global; because the list of accuracy ranges is captured as a span. |

@HamzaHajeir I'm going to try it, I'll tell you how it went. |
hi |
I meant after calling |

thanks. i got the code working - at least partly. do you have any idea what could cause this? |
Not, really. Perhaps something in the command issuer? |
How can I get the accumulated energy in Watts/hour?
I am using the electrical_power_measurement cluster and also the electrical_energy_measurement cluster, to obtain the current power data, such as voltage, alternating current and watts, but I do not know how to obtain the accumulated consumption data in watts/hour.
This is app_main.cpp code:
Then in the app_driver.cpp file I added the lines to update the attributes:
However, the following errors appear:
