Still struggling to find out the IP address of my inverter. Tried different IP scanners but don’t seem to find the correct one.
I have found the IP address of the WiFi dongle but not the LAN.
Both are connected.
Any tips on how to get a hold of it?
I have a SH10RT-v112.

Log into your router! Then plug and unplug until you know!
There is no difference in the connected clients in the router when I unplug the cable.
Does anyone now if I somehow can login to the inverter to see the IP-address?
I asked the company that installed the inverter and the battery if they could provide me with the admin login credentials.
I said I needed them for an integration.
They told me I had to sign a non-disclosure agreement with Sungrow to get an access key. But is that correct? Isn’t that for developers using the API, as for the creator of this integration, not me as end user of the integration right?
I mean, when you get the password you can change all the important settings, so it is reasonable, that they want to be safe.
I’m not sure if you can see the ip by connecting to the inverter hotspot, but you can try.
But if you unplug the inverter, be sure to wait some time, before looking for changed devices. The name could be Espressif. Also if you want to go really far the MAC address issuer (the first 6 letters) is either Espressif or Sungrow Power Supply (for modbus).
Another thing to look for is if they are using a router of their own to be able to remote login. That way you would never be able to see the IP in your router.
and specific error noted in this post:
Pymodbus: SungrowSHx: Error: device: 1 address: 4999 → Modbus Error: [Connection] Not connected[AsyncModbusTcpClient 192.168.86.140:502]
I’m getting the same error as this. My installation was running fine for months maybe over a year without issue and then suddenly on 28th August 4:05pm it stops working. As far as I am aware no updates were undertaken at that time or even in the couple of months before that.
I’ve updated supervisor and core and this has not helped. I’ve relooked at the Github code and made a few changes to bring what I have inline with that, but short of re-copying the whole lot into my installation I’m not sure what has gone wrong.
I don’t see any record on my inverter of an update, but I guess it is possible.
did anyone happen to see similar and find a route to a fix?
I’ve had no luck unfortunately- hoping your update sparks some new ideas
OK I got it going.
I worked my way though the FAQ for the integration one by one.
I don’t know what has changed, but I now have to use a modbus proxy.
After a full reboot it was working again. Yay!
This weekend I finally got time to examine my battery installation checking where all the network cables were going and why my inverter does not show up in my router.
I opened up the box where the CM10 (Checkwatt gateway) was installed and I now think I know why I can’t see the inverter on my network.
Conclusion:
The battery has a network cable that is connected directly to my network (through a switch).
The CM10 (a gateway that is controlled by Checkwatt) is also connected to my network.
Checkwatt is a company that offers a service where you lend out your battery for adjustments in the electric network (charge/dischange to balance the network) and you get paid for it.
I can see both the battery and the CM10 in my router.
But the inverter is not directly connected to my switch. It is connected via the LAN output directly into the CM10, that is why I don’t see it in my router!?
The first couple of weeks after I got everything installed, it was running on Self Consumption, not using the CM10. That is when I tried to connect to the inverter.
Now it has been taken over by Checkwatt and they control everything.
My plan is to use Self Consumption during the summer when my solar panels can charge the battery and use Checkwatt in the winters.
But I guess I need to unplug the LAN cable from the CM10 and plug it into my switch to be able to see it in my router?
Anyone understand what I’m talking about and have some input?

Maybe this is a silly question, but… I can’t find proper documentation.
What exactly is ‘External EMS Mode’ used for? How does it differ from the ‘Forced charge/discharge’ mode?
