Get external temperature to thermostat router (TZ-1148)

[kioelka]

Question

chip ESP32C6 IDF 5.3.0

I have a thermostat connected to the gateway in router mode, but I faced a question. in the examples all thermostats have their own temperature sensor and send in cluster 0x201 all attributes of the thermostat to the coordinator. but if I want to do the opposite how can I do it? i.e. I have a temperature sensor xiaomi LYWSD03MMC and I want to receive temperature reports from it. how can I do it at the transport level or configure smart home software to retransmit the temperature to the thermostat in any way?

Additional context.

If you are able to get the address of the temperature sensor, you can try to use esp_zb_zcl_read_attr_cmd_req to read the attributes from the specific endpoint on the temperature sensor. Please refer to our example: https://github.com/espressif/esp-zigbee-sdk/blob/d4af0c84351b75395a984277f6a55a6d7a46c07b/examples/esp_zigbee_HA_sample/HA_thermostat/main/esp_zb_thermostat.c#L61-L73

Thanks, it can get temperature. but, how to apply this code but in router mode instead of coordinator mode? i tried to edit the code and pair sensor, thermostat and coordinator, but by pressing "READ ATTR" button i get 0.0 celsius on "ROUTER" and homeassistant gets temperature from sensor

It's not related to the device type (ZC/ZR/ZED). You need to update the attribute of the thermostat cluster. I believe it should be LocalTemperature attribute.

I'm a little bit worried about your provided logs:

It seems that your thermostat failed to get correct value from the temperature sensor. If that was the case, could you please setup a sniffer and provide wireshark pcap files for both setups?

i noticed ZR thermostat tis triyng to answer coordinator 0x402 clutser but does it incorrectly

[lpy4105]

Going over the traffics, I think the behaviour of the temperature sensor is weird.

• Reading the MeasuredValue can't get correct value, but it can be reported with correct value.
• The reporting was not going through a binding table but to a fixed address "0x0000" which indicating the coordinator.

It's not obviously a issue in our SDK. Could you please also consult with the firmware provider of the temperature sensor?

On the thermostat side, the coordinator is continuesly requesting a customized attribute with manufacturer code 0x0234, can you please check if the device is correctly configured on homeassistant?

[kioelka]

Hmmm, read attribute packets always include zeros, but report packets always include correct temperature. Can I somehow “subscribe” to the reports so that they go to the router address instead of 0x0000 ZC?

and.. i have 3 temp Sensors (AQARA TVOC, Xiaomi LYWSD03MMC , TUYA)and all of them send zero to READ_ADTTRIBUTE fields

 static esp_err_t zb_action_handler(esp_zb_core_action_callback_id_t callback_id, const void *message)
{
    esp_err_t ret = ESP_OK;
    switch (callback_id) {
    case ESP_ZB_CORE_REPORT_ATTR_CB_ID:
        ret = zb_attribute_reporting_handler((esp_zb_zcl_report_attr_message_t *)message);  //here correct temperature but only in coordinator mode program jumps here
        break;
    case ESP_ZB_CORE_CMD_READ_ATTR_RESP_CB_ID:
        ret = zb_read_attr_resp_handler((esp_zb_zcl_cmd_read_attr_resp_message_t *)message); //here ZEROS
        break;
    case ESP_ZB_CORE_CMD_REPORT_CONFIG_RESP_CB_ID:
        ret = zb_configure_report_resp_handler((esp_zb_zcl_cmd_config_report_resp_message_t *)message);
        break;
    default:
        ESP_LOGW(TAG, "Receive Zigbee action(0x%x) callback", callback_id);
        break;
    }
    return ret;
}

In theory, report will send via bindings. The traffics has shown that you have bound the sensor correctly. However the reports were not sending as expected...

thank you very much. i tried again all sensors, only Xiaomi works well. araqa TVOC doesnt answer on attr read requset, status 0x86 (invalid attribute) TUYA answers on request, but send zeros. XIAOMI sends reports well and sends correct temperature by pressing button (read_attr)
