Although you did not mention it, can you clarify on whether or not you also have the Modbus app running on Homey (or any other Modbus app outside of Homey trying to connect to the inverter)?
AFAIK, the standalone Modbus app is not required to use the SolarEdge + Growatt TCP modbus app, but when both apps are running at the same time, they can interfere with each other. It is possible to run the apps side by side, but does require your to manually manage the connection from the Modbus app
Only Solaredge app is running, no other modbus stuff. Also tried device ID 2 but that isnât it. I can check the installer settings on the inverter and it show ID 1.
not really sure whatâs going on or what next steps I can take. Any suggestions ?
I donât have access to the Modbus settings for my setup. I had to ask my installer to enable it. I donât know about the protocol, but I did have to ask him to set the Modbus TCP parameter to âEnabled (unrestricted)â. I sent him the following instructions:
Title: Issue adding KOSTAL Plenticore Plus via âSolarEdge + Growatt TCP modbusâ (timeout)
Hi,
Iâm trying to add my KOSTAL Plenticore Plus inverter to my Homey Pro 2023 using the âSolarEdge + Growatt TCP modbusâ app.
My setup:
What happens:
Additional info:
Iâve created a diagnostics report from the app:
Diagnostics ID: 341153f1-b2a0-4404-befc-e74a33ec4af5
Could you please check whatâs going wrong with the Modbus connection / pairing for the KOSTAL Plenticore Plus?
Thanks a lot!
Welcome,
Note:
Unsolicited sending of diagnostic reports often is not appreciated
Note2:
kudos for the very detailed information provided!
Try changing modbus port 1502 to 502, which is the standard port number
Please donât reply here, move your post to the Solaredge+Growatt topic, thank you.
I try do bring my Emma and the Rest of my Photovoltaik in Emma with the solaeEdge + growatt ap. But it did Not work. I get Kontakt with Emma, modbus is on, but all I get is this:
Can anybody help?
Danke !

Welcome, René,
The Solaredge+Growatt app has itâs own special topic, like many apps have.
When you post your Q in there, youâll reach fellow device owners and the developer.
And often the first post has lots of howtoâs, FAQ and troubleshooting guides!
Hi Peter,
Thank you, will try it!
René
Iâm so sorry that you have removed flowcards BatteryFirst Timeslot2 and TimeSlot 3 in the Growatt SPH version 3.0.223. I used them both in my flows 
But it have also corrupted the existing device. By adding a new device helped, but still only with Battery First TimeSlot1âŠ
My device doesnât get updated anymore? Some values do get updated but the current power is not updated for 18 days now. The connection itself seems fine. Anyone a solution? Telnet on this port to this device works fine.
To anyone using Sungrow solar panels + battery:
Weird question, but is anyone else experiencing a difference in battery charging? For the last two years, âForced modeâ âStop 10â would fully stop the battery from charging. Nothing in, nothing out. Since last week, the battery has suddenly started to trickle-charge at exactly 100W when I give these commands. Not a huge problem, but definitely unexpected⊠O.o
I donât have 1 but the trick with emma is
default there is somewhere 0.0.0.0
switch to Modbus in the installer menu and then enter your Homeyâs IP address there.
see [APP][Pro] SolarEdge + Growatt TCP modbus - #1696 by JayR
you got some firmware update?
I think you solved it by now but it is always some dhcp ip change, firewall rule, vlan , using wifi
using a 2nd app which holds the port occupied.
I heard reinstalled helped , somehow the auto update caused some corruption
Yes I solved it. Thank you. I am running homey and ha. tried Solaredge jn ha as well. This caused the problems.
Hello everybody!
@Janalyzer Any luck in solving the issue you faced?
I have a similar Huawei SUN2000-4KTL-L1 inverter that Iâd like to integrate in Homey Pro.
The inverter has no dongle and itâs connected to the router via WiFi.
Is a wired ethernet connection needed to make this app work?
Has anyone succeded in making a SUN2000-L1 inverter work with this app?
Thanks a lot!
Unfortunately no. No solution so far. I even made things worse by messing with my inverter settings and now I canât connect to it at all. Iâm thinking about forking the other app for Huawei web data readings, because thatâs what Homewizard uses and it works fine. Itâs just a matter of fixing the app to allow the new login method.
Hi @Edwin_Biemond ,
I have your app running for some time now and everything worked well until 2-3 weeks ago.
I have a sungrow inverter, but the data doesnât come through anymore.
I tried several things: reinstall the device, deleted the app and installed the official version, I tried also the test version of the app,⊠Nothing does the trick.
Any suggestions maybe?
Thanks!
All the best,
Geert
Although your question is addressed to Edwin,
Did you check the actual IP address of the device as it should be a LAN fixed IP address. It is forgotten so many times. Just to make sure, check â
