Hi, can someone help with this error , after the last update from 2.8.6 to 2.8.7 for HA on a raspberry pi4
Requirements for huawei_solar not found: [‘huawei-solar==2.0.0rc6’].
Please update the integration. You are using an outdated and unsupported version.

Hey all - I’ve not checked in on this thread for a while as everything has been working great, thank you wlcrs!
I’m wondering if anyone has done the latest inverter update and if so, is everything still working?
I’m currently using two inverters, I connect to both via the inverter wifi and poll them individually, combining the figures using templates, which works great.
I’m also dynamically adjusting the battery charge amount, so that I can minimise the amount we push back to the grid (this helps the voltage not get too high and stops the inverters from shutting down due to over-voltage condition).

Just finishing migration from the older version to your latest version (from scratch) and it working great!!
Thanks for you guys effort and support!!!
My old version : V1.0.0 by Emilv2
My latest version : V1.1.2 by wlcrs

Hello to all
I’ve just installed a SUN2000-4KTL-L1
my question is (and others more)… where to place this?
- alias: "Huawei Solar inverter data polling"
trigger:
- platform: time_pattern
hours: "*"
minutes: "*"
seconds: "/10"
action:
- service: homeassistant.update_entity
target:
entity_id: sensor.daily_yield
Also another question
when battery is 100%, the “inverter active power” value changes to the “input power” from solar panels
with this, i can’t know what is beeing used to power the house
how can i get the “load” from house?
i tried getting the house consumption like in the standard energy panel in a few ways and in the end got to a version that seems to work alright for me
template:
- sensor:
- name: Home energy consumption
unique_id: home_energy_consumption
state_class: total_increasing
device_class: energy
unit_of_measurement: kWh
state: "{{ ((states('sensor.hourly_solar_yield_meter') | float) - (states('sensor.hourly_grid_exported_meter') | float)) + (states('sensor.hourly_grid_consumption_meter') | float) }}"
utility_meter:
hourly_grid_consumption:
source: sensor.grid_consumption
name: Hourly Grid Consumption Meter
cycle: hourly
hourly_grid_exported:
source: sensor.grid_exported
name: Hourly Grid Exported Meter
cycle: hourly
hourly_solar_yield:
source: sensor.total_yield
name: Hourly Solar Yield Meter
cycle: hourly
daily_home_consumption:
source: sensor.home_energy_consumption
name: Daily Home Consumption Meter
cycle: daily
monthly_home_consumption:
source: sensor.home_energy_consumption
name: Monthly Home Consumption Meter
cycle: monthly
yearly_home_consumption:
source: sensor.home_energy_consumption
name: Yearly Home Consumption Meter
cycle: yearly
i now get the daily/monthly/yearly load on the utility meters and can plot it in grafana

Same here bro. Did you got any solution for this?
I just put it manually in automation page
- First navigate to the automation page
- Then create the automation detail as below
- Then navigate back to Devices & Services
- Then click on the three dot and turn off enable polling for updates.
Done!
Hope this help!! 
Does anyone know which sensor represent real time energy export to grid?
I’ve just copied, but the data doesn’t refresh every 5s
maybe Rp3 can’t handle with so much data
PS: tomorrow will recieve a new mini-pc Chuwi Herobox just for HA

mine refresh every 10 sec. I guess 10 sec is the max value xD
maybe it is an HA limitation…
but what i really want is how to get “house consumption”
the value of “carga” (bellow - house)
Besides the RTU-to-TCP bridge, which cables can be used to properly connect to pin1/2 of the COM port?
I have some jumper wire cables available but the connector is too thin. The inverter is located inside so waterproofing is not needed.
You need the communications terminal to attach to that port, see: SUN2000-(2KTL-6KTL)-L1 Installation Video - YouTube. If you don’t have a power meter/battery, the installer might not have installed it at all. Hopefully you still have it lying around?
