[APP][Pro] Huawei FusionSolar Manager

[Andi]

Could you please use to Huawei Mobile App, connect to your Dongle and check the value there as well?

[Daniel_Diehl]

Hey. Danke für das super Mega Plugin! Ich hab jedoch das Problem, dass die eigentliche PV Produktion nicht gemessen wird. Wenn ich auf das Element klicke, sehe ich die Produktion. Aber nicht in dem Energieübersicht von homey.

Irgendeine Idee, was das Problem ist? Liebe Grüße und danke, Daniel

[Teddy]

It is set 6.500 there i checked it there to be shure.

[Andi]

Hast du das SUN 2000 Gerät auch hinzugefügt oder hast du es PV Produktion benannt ?

Bitte lade ein Screenshot des Wechselrichters mit allen Werten hoch. Dann kann ich vergleichen, ob da alle Werte vorhanden sind.

Danke

[Andi]

Could you please open a issue on Issues · andiwirz/com.huawei.fusionsolar · GitHub

Thank you

[Daniel_Diehl]

Ja, ich hat die SUN in “PV Produktion” umbenannt. Hier sind die Werte. “Solar Power” wird hier auch immer richtig ausgegeben (Gerade ist es dunkel )

[Andi]

Welches sun2000 gerät ist es? Modbus, emma modbus? Bist du auf der neusten Version der App?
Was für ein Homey Pro hast du?
…

Ich brauche alle Infos um zu verstehen, woran es liegen könnte.

Hi Andi, thanks for the app!

Meanwhile waiting for my Huawei Smart Dongle to use the Modbus TCP option, I wanted to connect with the OpenAPI solution. I have succesfully created the Northbound user within the installers account on fusionsolar. However, upon logging in throug the app in Homey (option SUN2000 (OpenAPI) I get the error message “no stations found for this account”. How can I fix this?

[Andi]

You have to grant the right permission to the newly created account on the fusionsolar website

[Koekie]

Thanks for your reply! I have granted the only possible permission in the creation of the account, see below:

EDIT: There was an additional setting in the app which triggered the API permission!

EDIT2: The app recognizes my inverter but it doesnt fetch any data into the Homey…

[Andi]

Did you try all 3 OpenAPI devices?

[Daniel_Diehl]

Hi,

Es ist ein SUN2000, alle 3 (LUNA, SUN, Meter) über openAPI angebunden. Habe den Inverter nun nochmal neu erstellt. Mich wundert, dass die Solar Power werde im Device auch angezeigt werden, aber eben nicht in das Energy Dashboard.

[Andi]

Das heisst, dass du hier auch keine Daten hast?

[ideenfrei]

Genau. Das sieht so bei mir aus

[Daniel_Diehl]

Genau.

[Andi]

Ich werde mir das am Wochenende mal genauer anschauen

Hello!

I have a Huawei PV setup with SUN2000-4KTL-L1 inverter + LUNA2000 battery + DTSU666 meter currently integrated in Homey Pro using the Growatt TCP modbus app.

The inverter has no dongle and it’s connected to the router via WiFi.

I managed to make the app Growatt app work with my inverter via WiFi enabling “Local O&M” on the inverter which opened port 6607 and using ID 0 (here below more details):

[APP][Pro] SolarEdge + Growatt TCP modbus

Hello! Hoping to provide some useful info, I share how I managed to make the app work with my SUN2000-L1 inverter via WiFi. I basically followed this guide provide by my installer for a similar HA integration: https://github.com/wlcrs/huawei_solar/wiki/Connecting-to-the-inverter#network-connection Using the Installer account, I enabled “Local O&M” on the inverter which opened port 6607 and (in my case) I used ID 0. The readings doesn’t seem perfectly integrated in Homey (i.e. the battery ca…

The communication with the Growatt app works fine, but the readings are not well integrated in Homey and the battery is not shown in the Energy tab.

@Andi app, on the other hand, seems to have an almost perfect integration of the readings in Homey (incl. Energy tab), so I’d like to switch to it.

I therefore tried to add the 3 devices via Modbus with the same IP addresses and ports I’m currently using, but without any luck (it returns a timeout error).

Any clue on what can be the issue?

Thanks in advance!

Most likely cause: the Growatt app is keeping the Modbus TCP connection open.

The Huawei SUN2000/SDongle only allows one active Modbus TCP connection at a time. As long as the Growatt app holds that connection open, the inverter will reject any new connection attempt with a timeout.
What to try:
1. Disable the Growatt app in Homey, then wait 30–60 seconds for the inverter to drop the old connection.
2. Then try adding the devices in this app again.
3. If the timeout persists: power-cycle the inverter for about a minute — that reliably resets any stuck connections.

Hi Andi
May found a bug. According to the device a have already generated 5.97kWh (which would be nice) → the correct value is 3.31 according to the fusion portal. How did you map that value? 30346?
or 30342 (which could contain a mix from pv and battery).

Asking because it’s wrong in the energy tab
