Issue configuring integration

[JxZZY94]

I have spent a couple hours trying to figure out how to integrate my Sigenergy (single DC inverter) to Home Assistant, and I am stuck on the "Couldn't connect" error.

I have asked my installer to Enable Modbus TCP Server Enable, confirmed port 502 and slave ID 1, and confirmed the LAN IP address is correct.
I have polled the IP and port on HA Web Terminal and it is reachable "192.168.1.4 (192.168.1.4:502) open"

Is there anything else I could do?

Thanks

Ask your installer for a screenshot of the settings.

Ask your installer for a screenshot of the settings.

I am experiencing the same

I finally got it to work, I asked my installer to disable, save, then re-enable Modbus TCP Server Enable. Might be coincidental but worth a try

I had a Sigen system installed last Friday and having the same problems, confirmed with Sigen support the system is configred correctly their side but I can't connect.

Same as others here, I can see it on my network, I can ping the IP, confirmed listening on port 502 but can't connect.

Any ideas?

Hi,
I have a similar issue, and my installer sent me pictures confirming the correct activation (see below).
Strangely enough I had to give him the IP of my HA server (see screenshot). Did you have to do this as well?

I asked him to disable and re-enable as you suggested, waiting for him to do it.

Thanks!

For anyone wondering, disabling and re-enabling the Modbus TCP (by the installer) also solved my issue.

The installer has done this and no joy im just trying to recheck the basics, is it the gateway that i should be connected to

Also is the slave address required as i have not supplied this? apologies if i have missed something in the documentation

I managed to get this resolved, there is a setting in the installers area where a server ip can be entered and it is saved called something like "configuration 1", this stops the integration from working. When they deleted this configuration and re-enabled the modbus setting it started working again. There is no need to put an IP address anywhere for the server.

Hope this helps!

Do you know how you get to this configuration 1 screen? I believe my installer has done the same thing, but I don't know where it is to direct them to it
