English below! Hallo OpenHAB-Forum! Ich habe noch aktuell wahrscheinlich ein leichtes Verständnisproblem und eventuell könnt ihr mir bei der Lösung helfen. Ich bin im Besitz von zwei SMA Wechselrichter (Sunny Tripower STP 9000TL-20 + 8000TL-20), welche beide per LAN angebunden sind und der Modbus…

[image] Hoerli: Which bindings do I need so that I can read the values The modbus binding should do. It has a SunSpec mode now AFAIK SMA inverters supports Sunspec.

Hello can you please specify your problem? You just need to install the modbus binding and configure your Things / Items. Items, Thing configuration (-files) here from OH2 should also work with OH3. Fist you may want to try it with SunSpec see here: [image] SMA SunSpec ove…

@Tuny Perfect! That was the info I had not found. But with the information I can only read the AC side, at DC comes only UNDEF. Are there other IDs there? According to the PDF document ( https://www.sma.de/fileadmin/content/landingpages/pl/FAQ/SunSpec_Modbus-TI-en-15.pdf ), the ID is in the range …

I am not sure what values are supported with SunSpec. I am using the “normal” modbus pofile from SMA. The configuration I also copied form other topics in the forum here. This should also fit for you I think. You just have to rename them (.items, .things, .sitemap) and put them into configuration …

That looks very good so far. The data is now coming in. Now I just have to adjust the names of all the objects a bit, so I can tell both inverters apart.

[image] Tuny: Also you need to install the Javascript traformation service and put them into “transform” folder. Hi Tuny, Could it be that divide3600.js is also needed? It would be great if you could provide this file. Many thanks, Selter

divide3600.txt (144 Bytes) Here the file. You only have to rename it (.js). divide10.txt (209 Bytes) divide1000.txt (144 Bytes) SMA.txt (856 Bytes)

@Tuny Oops, it seems that divide10.js and divide1000.js are also missing … And for .items the SMA.map will be needed.

sure, I edited the post before. I just saw that there is a quite good documentation here: [image] Modbus binding with Sunny Boy SMA inverter Installation Just for documentation here … I have installed the two inverters SMA Tripower 8 and SMA SunnyBoy Storage …

Hello all. It’s been a while now, unfortunately, but I’m only now getting back to deal with the topic forced. (The SolarLog 1200 is broken again :S) I have tried to add the SMA inverters now in an openHAB test instance to set up and not break my productive system. For this I used the linked data…
