@themmerle a couple more things ... Click on the Energy dashboard: Then you can play with your dashboards: I've taken the ones from @mkaiser and tweaked them for the two systems. |

@themmerle I've just run into this beauty: The unique_id is not the entity_id. That make what I am doing pretty hard. As I've only been running for a few days, I think I might kill all of my sensors/entities etc and start again (dropping all my history). But first I need to match up my unique id and name a bit better |

Hello, i would like add a second inverter, too. I tried the suggestions from this thread, but unfortunately it does not work. I used Notepad++ to manipulate the modbus YAML, i did the following; Thank you |

@Pirx63 I have two units and they are NOT setup as master slave arrangements (I'm not sure how common that is). I doubt that you would be in master slave either, and if you aren't, you will not get cummulative data from the units. If you are in master slave, I can't comment. Two questions:
If you answer yes to the first question, it will definitely have an IP address, and I assume it will have the modbus capability of my SG10RS. Mine shows up with no logical name in my connected devices on my router, so it was a case of trial and error. Maybe get the schneider electric modbus tester and start pinging ports. https://www.se.com/in/en/faqs/FA180037/ Grab an ip address from your router's dchp table that you suspect might be the wifi dongle, stick it into the tester app. Change the starting register to 5000. Hit Read. You might need to try a few times, because you might get a few errors. Remember it is pushing data to iSolarCloud regularly. You might get this, or a socket error a few times, so try at least 5-10 times. If you get no error when you click Read and you get something like this ... you have hit the jackpot. From the SunGrow doco ... port 5000 is the device type The reason for the second question is this: My SG10RS (single phase) has only one comms port - the wifi dongle. However, if you screw off the last cap of the dongle, there will be an RJ45 port in the end. I would recommend not using that, because when I did, the wifi was pushing data to iSolarCloud and the RJ45 connection (separate adapter) was getting push and pulls from me in Home Assistant. I don't think the comms module liked that much, because I was getting drop outs about every 4 days. I am now using the wifi adapter for modbus, so it is now controlling the push to iSolarCloud and the HA commands from modbus ... and it seems to be doing a better job. It has dropped out once in about 15 days. In the Sungrow doco, it explains that some port functions are not available if you connect via the ethernet cable through the wifi dongles. I didn't quite understand this ... I thought it meant that you could never get those port functions from the wifi dongle on my SG10RS. But I have disconnected my ethernet cable and am using just the wifi ... and now I am able to get access to those port readings. |

I wrote a step-by-step guide for adding the second inverter, using regexps and sed to (mostly) bulk-edit Hopefully it can save someone a bit of work. :) |

Hi All,
Did anyone of you add a second Sungrow inverter to HA? Should this not be possible by modifying these three files? "secrets.yaml", "modbus_sungrow.yaml" and "dashboard.yaml". Am I on the "woodway" ;-) by thinking that "secrets.yaml" should also contain Address and Port of the second inverter an reference "modbus_sungrow2.yaml". Am I correct thinking that Sensor Name sould always be unique and Sensor Address always reference the second inverter? Are there any more changes or additions to make? I would like to get your ideas before I start messing with those files and screwing my HA integration.
What is your take on this?
Thank you so much for your thoughts.
Kind Regards - Thomas
