Possibility to check if "Active Power Control Mode" is set to default "no limit"

[Jordan87]

Hi

Currently i have inverter+meter without battery.
Is there a possibility to check if we have currently configured "Active Power Control Mode"="no limit" ?
It seeams not.

Im able to set services i.e. "Huawei Solar: Set Active Power Control to 'Zero power grid connection'" or "Huawei Solar: Set Active Power Control to Maximum Feed Grid Power" but i do not see any entity where it shown which mode is currently activated.

When inverter starts to limit its power we can see it in entitis "Inverter state" or "Device status" but not when mode is changed but power not limited (i.e. when house consumption is higher then PV generation).

Did I missed something or this can be created as a feature request?

For me it will help in my automation when it will set "zero export" when price for exported electricity will be negative and diable it when price will be positive. :)

@Jordan87 either use the existing sensor.inverter_active_power_control (says inverter 1, but as inverter 1 in a cascade controls them all, that is the max also for a cacscaded inverters) or else to get it nicely formatted:

  # Provides maximum rate (Watts) that the inverter(s) can export power to the grid.

          {% set export_limit = states('sensor.inverter_active_power_control') %}
          {% if export_limit == 'Unlimited' %}
            {{ states('sensor.inverters_rated_capacity') | int }}
          {% else %}
            {% set export_limited = export_limit | regex_findall('Limited to (\d+)W') %}
            {% if export_limited %}
              {{ export_limited[0] | int }}
            {% else %}
              Unknown
            {% endif %}
          {% endif %}

            {% set match1 = inverter1 | regex_findall_index('(\d+)KTL', 0) %}
            {% if match1 %}

            {% set match2 = inverter2 | regex_findall_index('(\d+)KTL', 0) %}
            {% if match2 %}
              {% set number2 = match2 | regex_findall_index('(\d+)', 0) %}

            {% if match2 %}
              {% set power2 = match2 | int %}
            {% endif %}
          {% endif %}

          {{ power1 + power2 }}

NB: This is code for some standard add-on sensors I have to compile, just time shy atm finalising it.

Thanks @Roving-Ronin !

I dont know if I was blind or this entity sensor.inverter_active_power_control was not visible with old firmware on my inverter (yestarday i updated from SPC153 to SPC164)

btw
Your code isn't useful if I have only one inverter?

[Roving-Ronin]

Why not try it and see (paste i to the developer section).

PS. Yes it works.

[Jordan87]

I have added it (with small changes) as a sensors because I didn't know that there is this feature in developer section.

Without changes in your code(only -platform: template was added) those two entitis are having status unknown/unavailable.

With code correction via ChatGPT they are showing constant value 0

btw this error is visible if I try to use developer section

[Roving-Ronin]

Go back to the original code and add it to your setup.
Forgot Developer section won't work as the 2nd sensor isn't installed in you HA, so will fail.
