How to use Power Config Cluster

[mazis]

Hello Nordic!

I want to control the battery level, and set alarms... I know that there is a cluster callled PowerConfig cluster and I have been reading it, but I acan't figure out how declare it.

I have the following code (it is written in Spanish, sorry):

typedef  struct contexto_alimentacion_s
{
    zb_uint8_t battery_voltage; // Atributo 3.3.2.2.3.1
    zb_uint8_t battery_size; // Atributo 3.3.2.2.4.2
    zb_uint8_t battery_quantity; // Atributo 3.3.2.2.4.4
    zb_uint8_t battery_rated_voltage; // Atributo 3.3.2.2.4.5
    zb_uint8_t battery_alarm_mask; // Atributo 3.3.2.2.4.6
    zb_uint8_t battery_voltage_min_threshold; // Atributo 3.3.2.2.4.7
} contexto_alimentacion_t;

static contexto_alimentacion_t contexto_alimentacion;

ZB_ZCL_DECLARE_POWER_CONFIG_ATTRIB_LIST(lista_atributos_alimentacion,
                                        &contexto_alimentacion.battery_voltage,
                                        &contexto_alimentacion.battery_size,
                                        &contexto_alimentacion.battery_quantity,
                                        &contexto_alimentacion.battery_rated_voltage,
                                        &contexto_alimentacion.battery_alarm_mask,
                                        &contexto_alimentacion.battery_voltage_min_threshold);

This is part of a bigger code which is using doorlock cluster too. Ithink that I have to use what is asked in this older post, am I right?

Anyway, can someone point me in the right direcction? Where can I find some examples of the Power Config cluster?

Thank you very much!

Hello Mazis,

did you have to modify something in power config? Because I had to add

#define ZB_ZCL_CLUSTER_ID_POWER_CONFIG_SERVER_ROLE_INIT ((zb_zcl_cluster_init_t)NULL)

at the end of the zb_zcl_power_config,h

Otherwise it won't compile.

But I still can't read or report the battery voltage. Is there something special I have to set in main.c in the Zigbee Device Callback?

Thanks

Krystof

Hello!

I didn't changed the #define line you are saying... I have that line as follows:

zb_void_t zb_zcl_power_config_init_server(void);
zb_void_t zb_zcl_power_config_init_client(void);
#define ZB_ZCL_CLUSTER_ID_POWER_CONFIG_SERVER_ROLE_INIT zb_zcl_power_config_init_server
#define ZB_ZCL_CLUSTER_ID_POWER_CONFIG_CLIENT_ROLE_INIT zb_zcl_power_config_init_client

About the battery report. If you look the Zigbee reference, (I think that) the only reportable attribute is the remaining battery percentage. I don't know which coordinator are you using but to enable attribute reporting in mine, I had to bind and cofigure reporting for that attribute. If you are using the CLI example, the documentation is pretty good, I would take a look at it. What I do in my code to get the report of the attribute is this:

    UNUSED_RETURN_VALUE(zb_zcl_set_attr_val(MY_DOOR_LOCK_ENDPOINT,
                                            ZB_ZCL_CLUSTER_ID_DOOR_LOCK,
                                            ZB_ZCL_CLUSTER_SERVER_ROLE,
                                            ZB_ZCL_ATTR_POWER_CONFIG_BATTERY_PERCENTAGE_REMAINING_ID,
                                            &batteryLevel,
                                            ZB_FALSE));

I hope this helps!

Hello Mazis,

Thanks for reply, I was trying to get the reporting to work for almost a week now. 

I got myself second nrf52840 DK now, so I use the CLI example on that. 

I can already see the power config in the device cluster list in CLI coordinator

But I can't set the battery remaining value. It always gives me error 135 which is invalid Value

I am trying to set value 0x64 which is 100 which should correspond to 50% of battery.

6087.zb_ha_window_covering.h

zb_zcl_power_config.h

zb_zcl_window_covering.h

Here are my files, could you maybe take a look? How do yours zb_zcl_power_config.h, zb_zcl_door_lock.h and zb_ha_door_lock.h files look like?

Here is my implemenation in main.c:

    battery_percentage = 0x64;
    zcl_status = zb_zcl_set_attr_val(HA_WINDOW_COVERING_ENDPOINT,
                                     ZB_ZCL_CLUSTER_ID_POWER_CONFIG, 
                                     ZB_ZCL_CLUSTER_SERVER_ROLE, 
                                     ZB_ZCL_ATTR_POWER_CONFIG_BATTERY_PERCENTAGE_REMAINING_ID,
                                     &battery_percentage, 
                                     ZB_FALSE);
    if(zcl_status != ZB_ZCL_STATUS_SUCCESS)
    {
        NRF_LOG_INFO("Set battery remaining percentage value fail. zcl_status: %d,", zcl_status);
    }

in zcl_device_cb so when I send a command to the device it reports me battery.

battery_percentage here is type zb_uint8_t.

Thank you!

Best regards,

Krystof Vydra

Hi Krystof!

I am so sorry but I didn't find anything wrong in your code... All the sensible code is modified, and it looks correct to me. The 0x64 is valid, and the attribute type indeed, is zb_uint8_t.

The only things that I think might be wrong are:

- The number of ZB_HA_WINDOW_COVERING_IN_CLUSTER_NUM or ZB_HA_WINDOW_COVERING_OUT_CLUSTER_NUM might be wrong. Take a look and change them if necessary.

- I also had a issue declaring the cluster. I had to use the extended Macro to declare the attribute list of the power config. Are you using
ZB_ZCL_DECLARE_POWER_CONFIG_BATTERY_ATTRIB_LIST_EXT?

- When I wwas reviewing your code I found what might be a bug in my code. When you call zb_zcl_set_attr_val() and give it the ZB_ZCL_CLUSTER_ID_POWER_CONFIG as parameter, can you try to use the corresponding CLUSTER_ID for the window covering? Just like I am doing, although it seems wrong in my code.

- I would also try setting any other attribute to see if the problem is the parameters you are giving to the function zb_zcl_set_attr_val(). I would also change the cluster.

I hope this helps...
Cheers!
