Integration Solar inverter huawei 2000L

gohigher14 · May 11, 2022, 9:07pm

Who can help me out? I need a template to calculate the power used in the house , so i can see live what i’m using.

I’ve the HUAWEI SUN2000-4.6KTL with a power meter connected true rs485.

Thanks already.

As @dd77 mentioned here is his code to be pasted in configuration.yaml

template:
  - sensors:
      template_grid_feed_in:
      friendly_name: "Solar 2 Grid"
      unit_of_measurement: 'W'
      device_class: power
      value_template: >
        {% if states('sensor.grid_active_power') | int > 0 %}
          {{ states('sensor.grid_active_power') }}
        {% else -%}
          0
        {% endif %}
    
      # sensor used to show power flow from Panels to Grid and doesn't allow it to show a negative number only positive numbers
      template_grid_consumption:
      friendly_name: "Grid 2 House"
      unit_of_measurement: 'W'
      device_class: power
      value_template: >
        {% if states('sensor.grid_active_power') | int > 0 %}
          0
        {% else -%}
          {{ (states('sensor.grid_active_power') | int) | abs }} 
        {% endif %} 
      
      # shows the solar power being fed to the house and doesn't allow it to show a negative number only positive numbers    
      template_curent_solar_consumption:
      friendly_name: 'Solar 2 House'
      unit_of_measurement: 'W'        
      device_class: power
      value_template: >-
        {% if states('sensor.template_grid_consumption') | float > 0 %}
          {{ states('sensor.active_power') }}
        {% else -%}
          {{ (states('sensor.active_power')| float - states('sensor.template_grid_feed_in')| float) }}
        {% endif %}


utility_meter:
  grid_import_solar_daily_energy:
    source: sensor.grid_consumption
    cycle: daily
  grid_export_solar_daily_energy:
    source: sensor.grid_exported
    cycle: daily

and for lovelace card

type: custom:tesla-style-solar-power-card
name: 'Power Flow '
threshold_in_k: 4
hide_inactive_lines: 0
show_gap: true
change_house_bubble_color_with_flow: 1
grid_to_house_entity: sensor.template_grid_consumption
generation_to_grid_entity: sensor.template_grid_feed_in
generation_to_house_entity: sensor.template_curent_solar_consumption
house_entity: sensor.house_consumption_daily
generation_entity: sensor.daily_yield
grid_entity: sensor.grid_import_solar_daily_energy
house_extra_entity: sensor.grid_import_solar_daily_energy
generation_extra_entity: sensor.daily_yield
grid_extra_entity: sensor.grid_export_solar_daily_energy

it will produce this graph

@gohigher14 use https://code.visualstudio.com/ to edit your configuration.yaml file.

Add the above code in configuration.yaml

Install GitHub - reptilex/tesla-style-solar-power-card: Home assistant power card mimicking the one tesla provides for the powerwall app. from HACS.

and add Lovelace code to the lovelace card.

yousaf465 · May 12, 2022, 1:12am

this will go under the template: section in your configuration.yaml (if you don’t have a separate template file Splitting up the configuration - Home Assistant). Here are some rules for the templates. Templating - Home Assistant.

I have all my templates in configuration.yaml

you can always check your template in developer tools–> Template Editor Developer Tools - Home Assistant. Just copy your code and paste it there.

Thanks. It’s working now , only this entity i can’t seem to find it.
house_entity: sensor.house_consumption_daily

In the house bubble it is there , but i want to add this value as a normal entity card.

yousaf465 · May 12, 2022, 9:46am

it is simple, go to developer tools> and states and start searching for same value as your current value of the entity.

gohigher14 · May 12, 2022, 9:56am

that was what i did. But is was always showing me the wrong value. And now suddenly it’s showing the correct value. And i haven’t changed any setting

yousaf465 · May 13, 2022, 3:06am

for official looking card you can use GitHub - ulic75/power-flow-card: A power distribution card inspired by the official Energy Distribution card for Home Assistant

What is the exact difference between sensor.active_power and sensor.input_power?
I have a HUAWEI SUN2000-4.6KTL, but my smart power meter module is not yet connected over RS485 (forgotten by installer). The input power is mostly ± 20W higher than the active power value.

WongGendheng · May 14, 2022, 10:44pm

Maybe active power value accounts for losses by the inverter.

@wlcrs Set Up The Router In Bridge Mode - NETGEAR WNDR4300v2 User Manual [Page 113] | ManualsLib and What is wireless bridge mode and how do I set it up on my NETGEAR router? | Answer | NETGEAR Support. Is this the same thing as your OpenWRT code suggestion i.e wireless bridge but from netgear’s own firmware? I am already using fresh tomato in a different router but the issue is the range. So looking for a new router to be placed near the inverter. Don’t have the time to change the firmware, but can convert it to OpenWrt in future (already have experience with dd-wrt, OpenWrt and fresh tomato.

Hi,
is it also possible to change to port after you did the config?
I had it setup to port 507 on the inverter ip (192.168.200.1)
but after the installer did the firmware update, i think i have to change it to 6607? but i can’t find where to change tot port in the configuration

wlcrs · May 17, 2022, 6:02am

No. You need to remove and add the integration again.

jodewee · May 17, 2022, 6:19am

@wlcrs , do i loose the sensors then? or will it recreate an map those automatically again?

wlcrs · May 17, 2022, 7:39am

In my experience HA recreates them with exactly the same name again.

jodewee · May 17, 2022, 11:46am

ok will try, the installer comes next week to perform the upgrade. fingers crossed

Hi, I am trying to get the riemann logic posted on wiki and here to work but get this:

Invalid config for [sensor]: required key not provided @ data[‘platform’]. Got None. (See ?, line ?).

Code in configuration.yalm:

# Solar
sensor input_power_with_efficiency_loss:
- name: "input_power_with_efficiency_loss"
  unique_id: "input_power_with_efficiency_loss"
  unit_of_measurement: "W"
  device_class: power
  state_class: measurement
  state: >-
    {% set inverter_rating = 10000 %} # adjust this value to the rated power of your inverter
    {% set inpower = states('sensor.input_power')|float(0) %}
    {% if inpower < (inverter_rating*0.1) %}
      {{ inpower * 0.90 }}
    {% elif inpower < (inverter_rating*0.2) %}  
      {{ inpower * 0.95 }}
    {% else %}
      {{ inpower * 0.98 }}
    {% endif %}

yousaf465 · May 19, 2022, 7:41am

try this code in developers tools –> template

working for me

check YAML indent, to edit your configration.yaml use VS code https://code.visualstudio.com/

Hi, has anyone seen this before? - a dump at 5m to midnight that looks like a (close, but not exact) summary of the values. It really distorts the graph. I am using emulv2 via mqtt and either using the huawei inverters energy values or calculating from the voltage/current readings. This has been constant since the last 2021 versions.

yousaf465 · May 19, 2022, 8:56am

is your connection to the inverter stable?

BillK · May 19, 2022, 9:34am

Yes, its the same day after day - the last 5 minutes before midnight.
