Hi @bobelhage, did you - or anyone else - eventually succeed in writing (single) registers? I’m currently at the stage you were back then, reads work great, but writes don’t so anything, although the openHAB debug log states “Succesful write”. Thanks!
Hi Fernando,
Could you send me the modbus configuration, I’d like to set up a similar conf.
Thanks alot!!!
Georges
I will send you through PM. You’ve the smartlogger or without smartlogger?
I solved my problem. After I updated all Huawei components to the latest firmware version, I can write registers successfully.
Hello, does anybody try to implement this in OH4?
I’ve give it a try with the tutorial for OH3 but unfortunately that doesn’t seem to work.
I’am new to openhab and sure there will be some implementation differences between OH3 and OH4.
I’m trying to set it up with my OpenHab 4.
My SDongle version is V100R001C00SPC125
I have already change a Dongle parameter to Enable (unrestricted) in the Modbus-TCP configuration, so I have a connection from the openhab host to the inverter
pi@HOME:/etc/openhab/things $ telnet 192.168.1.28 502
Trying 192.168.1.28...
Connected to 192.168.1.28.
Escape character is '^]'.
I have two things configured as following:

The settings has been taken from thing file listed there: Reading data from Huawei inverter SUN 2000 (3KTL-10KTL) via modbus TCP and RTU with json configuration for full GIU control
Unfortunately OH4 complains about the connection

Can someone help there?
The modbus slave thing misses afterConnection delay parameter.
Thanks a lot! I don’t have a warning anymore, so I guess it’s a good sign and the connection has been established.
I have tried to add a new thing, which would read a data. I took the first from the list:
UID: modbus:data:slave102:Rated_power
label: Rated_power
thingTypeUID: modbus:data
configuration:
readValueType: uint32
readTransform: JS(divide1000.js)
readStart: "30073"
updateUnchangedValuesEveryMillis: 5000000
bridgeUID: modbus:poller:444a6f5e4d:slave102
However the one has readStart=30073, since my poll starts from 37000. Obviously it creates an issue
CONFIGURATION_ERROR
Out-of-bounds: Poller is reading from index 37000 to 37018 (inclusive) but this thing configured to read 'uint32' starting from element 30073. Exceeds polled data bounds.
When I tried to lower ‘start’ in the poll configruration, however after that change I have SocketTimeoutException any. I’m confused about the ‘start’ configuration in the poll. In this topic it looks like people are using any random number between 30000 and 37000. What is a proper setup?
Proper setup migh depend on inverter model/firmware. The error message you got indicates that you read to little data to map it to expected type. As far I remember you need 4 bytes for uint32 (32 bits / 8 per byte => 4 bytes => 2 data registers). Make sure you adjust also read length/end.
Overall advice from huawei support I got was to read larger blocks but less often. The timeout might be result of improper handling of errors on SDongle/inverter, generally you can then assume that configuration is invalid.
Is there any documentation to check what are the address of those registries ? Otherwise it’s a high chance that I will be reading some random data. For instance I’m reading an address of 37002 and it gives me some value between 10,000 and 50,000. How would I know what I’m reading?
After reading the thread again as well as “SUN2000L V200R001 MODBUS Interface Definitions” doc file now I get it … and what’s important I made it running.
As I have all the data, I want to visualise it. Is the energie.widget.json file shared there applicable for OH4?
I don’t have much an experience with habpanel. How can I add that widget?
Each UI is a separate component, you might look at widgets shared in marketplace category as they have some examples of PV/energy widgets, but for mainui.
Ideally if you run into troubles with habpanel widget you can start new thread with more precise description of issue.
Hi,
with the help of this topic I was able to integrate my Huawei inverter into OH.
In general its working fine, however I receive random timeout errors with the setup below.
Question:
Any best practice / guidance someone can share on configuring the connection / timing / retry parameter in a better way?
Thanks in advance for any help!

I wrote some time ago about this, there is a severe bug in SDongle, it confuses requests when multiple connections are being made. Make sure you have only one tcp connection at the time!
Don’t ask how I found it. 
That sounds reasonable.
I only have OH connecting via modbus to the dongle and using the fusion solar app. As the app is not using modbus it will not count towards the connection limit (at least that’s my understanding).
There is no other device / server (beside OH) that will connect to the dongle.
How can I configure my things, that they do not create multiple connections (I only have 1 tcp thing)?
Hi Matze,
would it be possible to post your full setup? Items, things etc?
I don’t get it working unforunately :-/
Thanks in advance.
I can have a look later, as I have managed everything via UI I need to copy and paste this.
I tried item based configuration before an also was failing, as all things went online at the same time and to many poller sending requests. Only if I enable one thing slowly after another, it will work.
Maybe that’s already helpful to know

Which firmware do you have? I get every Bridge and Thing online, but the Items only contains NULL values. And the log file is full of error…

works for me
What I read from the error message is, that your script transformation is not working correctly.
Try without transformation first to validate, if the binding is working and you see the raw data.
