Thanks a lot, so it seems still not solved on the ethernet port. Do you find the wifi reliable enough?
I am using a very small Mikrotik router to connect to the inverter and it’s not great for wifi. It’s a wall distance away from the inverter and the signal is fairly poor. I am considering drilling a hole and putting the router in the fuse box next to the inverter, there the signal is decent. Or use a different router with better wifi reception, but I don’t really want to spend more money on this.
Anyway, sometimes the router disconnects and I have to reconnect it manually. But apart from that, I have no issues. I get the data every 30 seconds from the inverter and as long as the wifi connection is ok, it works flawlessly.
P.S. regarding the firmware, I did let Huawei know that for me it doesn’t work properly and they said they didn’t have any complaints about it yet. If more people get to test this and if this can be reproduced, then they can work on a different firmware.
Anyone found modbus Api for Luna 2000 battery? Want to be able to set charging parameters and read our status.
Hi, I’ve SUN2000L1 + LUNA2000. I have running EMILV2 component, but I’m unable to make it work with battery = true option. When I tried, log returns DEVICE NEEDS UPDATE! and sensor doesn’t appear. Can you check the issue @Emilv2 ? I already found that error in this thread before, but without answers or fix.
Thanks in advance.
SUN2000-8KTL-M0 + SDongle+v5 FE. I also updated sdongle to version SPC120 and can access TCP port 502 from ethernet, but can’t access inverter registers. Also now FusionSolar app can login to sdongle from my lan network no need to connect to WIFI SSID:SDongleA-HV??? 
Success. Managed to run HA huawei_solar sensor via ethernet and SDongle. Warnings

I can confirm, after adding unit=1 it is also working for me. I only check in python under windows.

@Emilv2
Maybe you can add new option in config to use it with ethernet?.

I have to integrate 2 sun 2000l, they are in the same network and obviously have two different ip’s. if I add some configurator:
sensor:
- platform: huawei_solar
host: ‘192.168.1.153’
so it detects one, if I have to add the second ???
if I add one more
host: '192.168.1.95'
but by mistake. how should i do ??
@Emilv2
PLEASE… i need it too… 
Now, with last firmware SPC120 the SDongle have modbus over port 502… under FE connection
I’ve checked from my pc using (slave 1):
with this… we don´t need to have middle hardware to do it…
@Emilv2 great job… and you are very kind to share you excellent work
SUN2000-5KTL-M1
SDongle (firmware: SPC120) with Fast Ethernet cable connection
I made it with HA ModBus.
using “slave: 1” inside the sensor definitions
But i can’t have data @sec, it stops HA and i need to shutdown rpi
I’m working fine with scan_interval: 10 (but for me is poor)
modbus:

I have problems after sunset… it seems the inverter ModBus STOPS
Any one have some information about that?
Some configuration with FusionSolar?
Can someone explain how to update the dongle firmware?
Hello gieljnssns
-
Send an e-mail to [email protected] requesting the firmware package (zip file)
You need to detail your devices SN (Inverter and SDongle) -
With FusionSolar connect you smartphone to WIFI SDongle AP, not the inverter SSID
(here, i needed to restart my inverter, the SDongle SSID only appear during startup, and it seems easier to use QR code) -
After connection, select:
Configurations » Update firmware » select package file » and wait…
(keep your phone near the SDongle…
) -
When finish (about 10min) restart inverter
DC » OFF and after that AC » OFF -
Wait 15 seconds… and AC » ON and DC » ON
Voilá
There is an issue in the ModBus integration which hangs the Lovelace interface:
Current workaround is downgrade to core-2021.4.6 and wait for 2021.6.
The issue comes from the upgrade of the pymodbus library which they have been updating lately so it is possible that Emil integration broke a while ago due to a similar reason.

Thanks… already downgraded…
I had made a custom component from this core/homeassistant/components/modbus at 2021.4.6 · home-assistant/core · GitHub
So you can stay on 2021.5.x
Hello,
could you please tell me, where you were able to download firmware SPC120 for the Smart Dongle?
My environment doesn’t offer v120 - only v118 - therefore Modbus TCP is not working via FE?
With Huawei ‘Device Upgrade’ I can only choose btw. v116 and v118… 
Would be great to share a link or the upgrade package itself!!!
Many Thanks!

I have a Sun2000 5KTL L1 (1 phase) inverter. The integration works perfectly, but I noticed that the following parameters are always 0:
grid_exported_energy
energy_used
Is this normal, or do I need to change to configuration to see those values?
I think those properties are available only when power meter is connected to the inverter. Mine shows some big values :), but i ignore them.
Grid exported energy 21474836.47
Grid accumulated energy 21474836.47

@Emilv2 any fix for this? I have set temporarly battery = false so that it works without battery info.
