Matter ESP32 Energy Management Example#

This example demonstrates the Matter Electric Vehicle Supply Equipment and Water Heater example application along with several other energy management clusters on ESP platforms.

Please setup ESP-IDF and CHIP Environment and refer building and commissioning guides to get started.

Enabling ESP-Insights:#

  • Before building the app, enable the option: ESP_INSIGHTS_ENABLED through menuconfig.

  • Create a file named insights_auth_key.txt in the main directory of the example.

  • Follow the steps present here to set up an insights_account and the auth key created while setting it up will be used in the example.

  • Download the auth key and copy Auth Key to the example

cp /path/to/auth/key.txt path/to/connectedhomeip/examples/energy-management-app/esp32/main/insights_auth_key.txt

Build time configuration#

  • Application mode: By default the example app will run the EVSE example, however this can be changed using the idf.py menuconfig command and searching for:

    ENABLE_EXAMPLE_WATER_HEATER_DEVICE
ENABLE_EXAMPLE_EVSE_DEVICE

  • Test Event Trigger support: By default the EVSE, Water Heater, Device Energy Management (DEM), Energy Reporting test event triggers are enabled in the build. To turn these off run idf.py menuconfig and search for the following config entries:

    ENABLE_DEVICE_ENERGY_MANAGEMENT_TRIGGER
ENABLE_ENERGY_EVSE_TRIGGER
ENABLE_WATER_HEATER_MANAGEMENT_TRIGGER
ENABLE_ENERGY_REPORTING_TRIGGER

  • Device Energy Management feature support: Depending on the capabilities of the device it may support Power Forecast Reporting PFR or State Forecast Reporting SFR. However it is not allowed to support both of these at once.

    By default PFR is enabled in the build. To change this run idf.py menuconfig and search for the following config entries:

    DEM_SUPPORT_STATE_FORECAST_REPORTING
DEM_SUPPORT_POWER_FORECAST_REPORTING

    Note only one of these can be enabled to meet Matter specification conformance.

    When running in test events, some test cases (e.g. TC_DEM_2.7 and TC_DEM_2.8) depend on the correct setting to be used in the binary DUT.

Cluster Control#

  • After successful commissioning, use the Energy Electric Vehicle Supply Equipment cluster command to disable/enable charging and discharging.

        $./out/debug/chip-tool energyevse disable <NODE ID> 1

        $ ./out/debug/chip-tool energyevse enable-charging 0xFFFFFFFF 6000 32000 <NODE ID> 1 --timedInteractionTimeoutMs <Time>
