With the official Growatt integration being broken, I was looking into the available alternatives and found it a bit overwhelming at first. So I tried to break down all the available options, their advantages and disadvantages and how they relate to each other. And finally I described which of them I picked for my setup and how to configure it. I hope it helps.
Please note that I am far from an expert on all this, so I might not be able to answer any questions you have, but ask away anyway and maybe otherās can chime in to clarify.

Hi Andreas, thanks for the write down. For me it wasnāt clear how to go ahead with Grott but now with your explanation Iām going the same road you have done. With the addon.
Andreas - thank you so much for taking the time to write down a consolidation piece for a topic that had become very confusing. You presented in such a clear way, it really really helped.
Unfortunately Iām still getting something wrong, or Growatt have done something which stops me moving foward. If anyone has any suggestions Iād be very grateful.
I have SPH5000 and MIN 2500 TL-X plus batteries. Iāve followed Andreas with following actions but without success:
Removed old Growatt Core Integration
Installed GROTT addon (2.7 current stable), configured and have it running.
Iām hitting a brick wall trying to reconfigure either of my Dataloggers (a ShineWifi-X stick and a ShineWifi-S) to successfully start sending data to Homeassistant.
Method A (put dataloggers into AP mode (succeed), log on to AP (succeed) find datalogger web page at 192.168.10.100 (fail - no web page found there, but IP address confirmed)
Method B use growatt server to reconfigure the dataloggers. Took a while before finding āAll Devicesā arrow in the My Photovoltaic Devices section which allows access to Datalogger Setting panel. I set IP to my homeassistant IP address, left Domain empty, and set port to 5279. It seems like which ever parameter has the radio button selected when you click the Yes (save) button is the param that is saved. Saving those and waiting for Homeassistant Grott Log to show any incoming data produced no results. Other options in the Datalogger Setting panel are āUpdate Dataloggerā (appears to be firmware update), Restart Datalogger (appears to wipe out the IP and port custom values back to blank) and āClear Data Logger Logā which Iāve not tried.
Method C find dataloggers on your home network and browse to the Growatt Shinelink/X Setting Center at that internal IP address (fail - I can only find external 213.x.x.x addresses for both dataloggers, and despite trawling through Fing addresses for my network and pointing browser at any possible contenders, I have not found these Shinelink Setting Centre pages anywhere.
I managed to confirm my issue was not a communication problem with Grott on port 5279 by using putty to attempt to open a connection with the IP address and that port, which produces an entry in the Grott log āGrowatt packet receivedā but invalid data record, understandably.
I cannot seem to find a way to configure either of my data loggers to point to Grottā¦ does anyone have any suggestions please?
Did you solve the problem described above? Or did you change to different approach?
I own a Growatt 2500 XH Min which seems to be a bit newer and is maybe not supported by the stable branch of grott? I did order the ShineLAN-X stick, but didnāt tried it yet.
[update] it is working now, I found the parameter to be changed in the web frontend and could point the IP to HA. Iāve installed grott 2.8 beta and it is working, still passing to the cloudā¦
However, I think I change to a local approach, either by ESPHome or Modbus to TCP/IP.
