Domoticz

If your SMA can be reached without SSL, please give it a try. (e.g. http on port 80)

If your Syno is really too old, it is possible that its openssl libraries do not support the underlying more recent TLS versions.

I I can only reach my SMA via https, I can't find a setting to disable https. (Tripower 4.0 with firmware 3.10.10.R).
My Synology is a RS812+ with DSM 6.2.3-25426 Update 2

SSL can be tricky.
Old protocols are e.g. SSLv3, TLS1.0
Newer include TLS1.2, 1.3.

There must be a matching protocol between the client and the server, and then a matching cipher.


The user manual https://manuals.sma.de/SBxx-1VL-40/en-U ... 30027.html seems to indicate that http is supported.
This means connecting directly to the IP address of your inverter, not the sunnyportal.com website.

192.168.0.4 redirects to https://192.168.0.4 if I open the webpage in a browser.
I searched within the settings of the SMA but can't find any settings, not for security, SSL, TLS, 443, ...

Could you make a tcpdump and share this?
Would be something like:

tcpdump -i any -w capture.pcap host 192.168.0.4

Let it run for a minute and than stop with ctrl-c so it has captured at least one try by the plugin to connect to the sma. Share the generated file called capture.pcap.



You can share it in a private message if you prefer that.

I can't get tcpdump to do anything (i'm trying with windump).

What do you expect to see?
Is is something that I can get with Wireshark?

You should run it on the synology device you run domoticz on. I want to see the ssl handshake process of the plugin with the sma device.

Zipped the pcap file.

In the log I do not see a SSL handshake, but I see it tries to setup the connection via HTTP port 80. What is you current configuration? Have configured it to use HTTPS? Can you share a screenshot?

I switched from synology (did not work) to raspberry pi. I installed python, git and pip and i can add the hardware. I see 2 devices but no data.

The error log is:
2020-12-02 13:16:52.186 (Zonnepanelen) No valid response from SMA inverter on 192.168.178.49; {'err': 404}

Any idea?

Can you provide de full debug log of the plugin including initialization?

Go to hardware, select the SMA Sunny Boy Solar Inverter and press update. This will trigger a reload of the plugin.
Than go to log and copy the full log output.

New log and printscreen of settings attached.

Thanks, For some reason I do not see the SSL traffic. Can you try with -s 65535 added to the command?

tcpdump -i any -s 65535 -w capture.pcap host 192.168.0.4

I let it run longer and did a update on the hardware in Domotics while running.
New log attached, it looks the same for me

Changed to https and now the kwh is visible!

What Synology and what DSM version did you used?

Strange. I would expect something like this:

Synology 211+ en 6.2 hardware

That is the same software version as my Synology.
Maybe @rklomp is right and it is caused by the openssl libraries.

If I do a Google search on openssl tls synology I only find information about the ssl certificate on the Synology itself, nothing about SSL connection to another device. Is there any way to make sure this is the problem?

I think my problem is that i couldn't install a recent domoticz version (like node-mydomoathome-0.2.39.spk) because my hardware did not allow me to install node.js_v4!

But it is now working great on my raspberry pi!
