Question: Reporting of AnalogInput Cluster -> PresentValue (IDFGH-14497)

[ummarbhutta]

Hi,

I am building a sensor using ESP32H2, which will measure weight and transmit it over AnalogInput->PresentValue to the network. Following are details

Hardware platform: esp32h2
ESP-IDF version: v5.3.2
Type of device: Zigbee end device
Cluster used: AnalogInput
Attribute used: PresentValue
Home Automation System: HomeAssistant (v 2025.1)
Network: 35+ devices (mesh)
Sensor -> Coordinator: This sensor is placed far from coordinator, so no direct connection, but joins network using Routers and have good signal strength.

Problem # 1 - How to configure reporting:

• I am having hard time to find any documentation/reference code to configure reporting from this end device, I know there is a way but can't make it work. The solution which I am using is as follows, i.e., defining the function below and calling it as per my needs, but no way to automatic report configuration, so that I only call esp_zb_zcl_set_attribute_val and rest is done automatically.

void report_weight_attr(uint8_t ep)
{
    esp_zb_zcl_report_attr_cmd_t report_attr_cmd = {
        .address_mode = ESP_ZB_APS_ADDR_MODE_DST_ADDR_ENDP_NOT_PRESENT,
        .attributeID = ESP_ZB_ZCL_ATTR_ANALOG_INPUT_PRESENT_VALUE_ID,
        .direction = ESP_ZB_ZCL_CMD_DIRECTION_TO_CLI,
        .clusterID = ESP_ZB_ZCL_CLUSTER_ID_ANALOG_INPUT,
        .zcl_basic_cmd.src_endpoint = ep};

    esp_zb_lock_acquire(portMAX_DELAY);
    esp_err_t status = esp_zb_zcl_report_attr_cmd_req(&report_attr_cmd);
    esp_zb_lock_release();
    if (status == ESP_OK)
    {
        ESP_LOGI(TAG, "Send Weight 'report attributes' command");
    }
    else
    {
        ESP_LOGE(TAG, "Send Weight failed, with error code '%d'", status);
    }
}

Problem # 2 (may be not directly related to this community):

Even with the above code the HomeAssistant doesn't show values directly unless I call Read Attribute explicitly, details are already added here.

For sake of testing, if I publish the report on HumidityMeasurement cluster as below, everything starts working fine (Entities are updated on HomeAssistance as soon as reported from FW).

void report_weight_attr(uint8_t ep)
{
     esp_zb_zcl_report_attr_cmd_t report_attr_cmd = {
         .address_mode = ESP_ZB_APS_ADDR_MODE_DST_ADDR_ENDP_NOT_PRESENT,
         .attributeID = ESP_ZB_ZCL_ATTR_REL_HUMIDITY_MEASUREMENT_VALUE_ID,
         .direction = ESP_ZB_ZCL_CMD_DIRECTION_TO_CLI,
         .clusterID = ESP_ZB_ZCL_CLUSTER_ID_REL_HUMIDITY_MEASUREMENT,
         .zcl_basic_cmd.src_endpoint = ep};

     esp_zb_lock_acquire(portMAX_DELAY);
     esp_err_t status = esp_zb_zcl_report_attr_cmd_req(&report_attr_cmd);
     esp_zb_lock_release();
     if (status == ESP_OK)
     {
         ESP_LOGI(TAG, "Send Weight 'report attributes' command");
     }
     else
     {
         ESP_LOGE(TAG, "Send Weight failed, with error code '%d'", status);
     }
}

Questions:

• Can anyone help me on problem # 1 and point me to a reference code.
• Is problem # 2, related to ESP-IDF or perhaps a quirk thing on HomeAssistant? I hope there is not a special way to publish report for AnalogInput cluster, and also I have not hit some bug in under laying zigbee API?
