hi this is a comparison of fusion solar exported energu in 1 day vs italian Distribution System Operator meter:
Fusion solar exceeding about 2% :).

@wlcrs Hi thank you very much for your effort on the integration really done a great job. Please is there any way how to add historical data to the sensors? I have two use cases when it would be really helpfull:
- not using integration from the beginning but connect it later
- If the HA is down and missed data from inverter cannot load it when it comes online
Is there anything we can do about it? I would be glad to spend some development time to allow it but Im not completely familiar with HA or huwai solar concepts. but would definitely try with some guaidance. Thank you very much
I’m not aware of such a feature in the HA API. Maybe you can find something on developers.home-assistant.io?
I have already successfully downloaded historical data from the inverter, so that part would already be covered (mostly).
I created the PyFusionSolarDataRelay github project which currently can relay data from Huawei cloud to InfluxDB and PVOutput.org. This project fetches the data from the Huawei FusionSolar Kiosk backend.
I think I’ll probably add MQTT support soon, which could then be routed to Home Assistant. Most of the code is by the way based on Grott, which is a sort-of-similar project for Growatt inverters.

MQTT support has now been added to v1.0.2.
That means PyFusionSolarDataRelay kan now forward FusionSolar Kiosk data to:
- PVOutput.org
- InfluxDB
- MQTT topics
It’s quite easy to subscribe Home Assistant to the MQTT topics (if MQTT is implemented)
I’ll add some home assistant templates soon to show how you can subscribe to the MQTT topics for setting up the energy dashboards etc.
If anyone can’t wait and would like to provide some assistance: Here are the basics for another inverter type which need to be ported to the PyFusionSolarDataRelay data format.

Finally I got answer from Huawei Technical Support about the reason why it happens: the inverter works very inefficient (15%-20% losts) if its operation mode is only to follow the home energy demand , the proper configuration to get the optimal efficiency of the inverter is in the mode converting all the PV energy generated, it means injecting into the grid the energy not consumed into the home. I changed the inverter configuration and now it works with the correct efficiency.
Have you solved this issue? Which mode do you have configured your inverter?: following only the home energy demand or converting all generated PV energy?
See may comment, may be could help you if it is your case: link
Hi all,
I have followed good practice and (skim) read through the topic. Can I please check my understanding of how to join the party? For context I have a Sun2000 and a Luna 15KWh battery at home.
I have two wifi points, one is the connection to my home network (192.168.1.x) which is the connection that then goes on to populate my FusionSolar app information.
I also have the Sun2000 AP beaming away on 2.4Ghz.
In order to use this component to extract the data I need to bridge the two networks, 192.168.8.1 and 192.168.1.x.
Is that correct? After I have done that and can get my HA to see the inverter I am good to go?
Many thanks
John.
just start here:
Hi everybody!
A bit off-topic here as I think most of the conversation is geared towards getting the data directly from the inverter through WiFi, but I have just uploaded a configuration to get the data from the inverter using EPShome and Modbus RTU. This has been rock solid for me for as long as I have had it and is easier to setup than what one might think.
One thing to keep in mind is that you really need to put your wifi-router close to the Sun2000. The range of the Sun2000-Wifi is extremely low. I had my router in the same room as the Sun2000 (my garage) about 3 meter away and got lots of disconnects. Moving it to about 1-1.5 meters from the inverter, the connection is rock-solid. It has been up for over 22 days now.

Could be. I never really tried the WiFi thing. I had already flashed the first version to the ESP before getting the inverter. Once I figured out the timings, I only have trouble when I try to “improve” the code. Otherwise it has been rock solid since easter (2 months already)
Hello all,
I have been using Emilv2s integration for a while and it’s been great, finally got everything working including the energy dashboard. However I upgraded the inverter because it kept dropping the management data and everytime I logged on it wanted me to upgrade so I finally let it… I knew it would break anything.
Anyways I’ve reread the thread and it seems they have left a port open on 6607, I didn’t see that port open but it’s high. I normally connect directly to the inverter wifi AP with a RasPi anyways…
Pictures attached
Few questions-
Can I read the data with Emilv2s integration by simply upgrading the inverter and changing the port to 6607 in config.yaml?
What is a smart dongle, not sure if I have/need one?
Should I update the MBUS version?
Is it better to use the other integration, test it out on this version that I know works then update the inverter and change the port to 6607?
Anything else I should know?
hey guys, such an amazing amount of work and content in this thread, thank you.
figured i’d ask here as maybe someone has a quick answer, i could not find it in the thread but there are 1700+ replies…
i am using https://github.com/wlcrs/huawei_solar and would like to get an ever growing sensor showing my house’s total energy consumption(kWh). the available data is
and i can’t for the life of me figure out how to get basically this from the energy panel
thanks again guys
Hi all. Forgive me for possibly going over something again, but I have set up Home Assistant from scratch in a VM, it’s searched for everything on my LAN and I realised that I couldn’t see my Huawei solar there despite the installer asking for my wifi password etc. I’ve therefore done some reading of this thread and worked out that I needed to use the internal Wifi of the inverter. I’ve gone out and bought a wifi bridge, configured HA with a second NIC with DHCP and received an IP address from the Huawei. I can ping the inverter from HA although it loses about 1 packet in 10 currently (that might be the siting of the wifi bridge or the inverter being too busy to ping, but I can troubleshoot that later).
At this point I think I’m ready to integrate an add-in to see/control the solar, but i’m not sure what I’m doing there - the start of this thread mentions Emilv2’s project which required me to install HACS (managed that) and then copy some files into a location (although a button on the component seemed to handle that for me) but now I’m not sure how to kick that project into life - I’ve edited the configuration.yaml file with my own inverter’s IP address, but still nothing’s popping into life and I’m not sure how to make it happen?
Also, the end of this thread mentions wlcrs’s project which seems to be different, but maybe what I want instead - i’m not sure? is one project more advanced than the other? do you need both to co-exist? and finally what do I do next?
(TIA!)
If you can ping your inverter, it sounds like you have managed the tricky part with bridging the networks!
You should really use the wlcrs-version https://github.com/wlcrs/huawei_solar.
Emilv2 is an old version, so remove that if you have it installed.
If you can reach your inverter, you should only need to configure the huawei_solar-integration and be good to go. You do not need any configuration in your .yaml-config. You configure with the UI.
Marvellous, thanks. Got it showing details now.
Is there a reason that “Daily Yield” doesn’t show the amount of kwh i’ve put into the batteries? I’ve filled my 10kwh LUNA2000 batteries in the 6 or so hours from sunrise to now, but Daily Yield is showing ~4kwh. Are there any customisations I should be considering to show accurate figures?
Also, someone mentioned above the temperature of the inverter - I don’t see that as a returnable figure?
Check the FAQ in the readme on github.
There is a section on:
The “Daily Yield” value reported does not match with the value from FusionSolar?
About the temperature, I think you can see the temperature if you have optimizers. Not the temperature of the inverter itself.

Thanks - I won’t bother about the inverter temps as I don’t have any. I’m a total noob with HA though (but not with networking), so i’ve read the Daily Yield section and understand why it’s a flawed calculation but I have absolutely no idea what to do with the code snippets on that wiki page (Daily Solar Yield · wlcrs/huawei_solar Wiki · GitHub) - where do I put this?
