Hi everybody,
Someone has experience how integrate Modbus TCP in Huawei solar inverter?
Best regards Cristian

Do you have some documentation on the available registers? Without this info there's not much that can be done.

You need dongle to communicate with Modbus TCP.
I have integrated two SUN2000. First unit communication is not the best (sometimes it gonna show wrong values or zero but controlling commands work). Haven't diagnosed that if problem is in the network, dongle or inverter. With other one all works like a charm. Make sure that dongle FW is latest. Here is register list for SUN2000. https://javierin.com/wp-content/uploads/...itions.pdf

How do you set the dongle in the app? can you share the screen shot? Another info, do you lose the cloud if you connect the modbus? Thanks for the feedback BR Cristian

Here is manual how to set Dongle:
https://forum.iobroker.net/assets/upload...-guide.pdf No, You don't lose fusionsolar connection when controlling and monitoring inverter over modbus TCP. I made system what I'm offering to my clients. When electricity price is low then sending command to inverter that it's time to buy from grid and charge battery. If price is high then sending command that it's time to sell. So far have integrated SUN2000 over dongle and SmartLogger3000. Same system works on SolarEdge and Goodwe inverters (if they have battery packs) Let me know if you have any additional questions about connection...

I will receive my PV system in a few weeks and would like to integrate it into my Schneider Homeylink. Unfortunately I have never worked with Modbus.

I moved to scripting with special delays for reading and writing. On second project delays was not needed (maybe dongle firmware update has solved these problems) so you can try to use that template what I created. I add two files template and esf file (please change "Huawei Sun2000 Group Addresses.json" to "Huawei Sun2000 Group Addresses.esf" - can't upload esf file in here) so you can import file in Utilities -> import ESF file. Then variables is created automatically. Change group address as you need... Also you can try to edit/remove "read_delay": 1 in json file so maybe it's not needed now. If you have any problems, let me know.

Hi Fleecable, i think there is something wrong in your profile as you did not specify the bus_datatype, just the datatype further i see you mis also some datapoints of the list from Huawei, i would add all and just map the ones you need further you get for example grid voltage in as 5000 but this must be devided to 50.00 Hz If i have some more time i will tweak it.
