We had lengthy discussions in an old thread I now published my version of the Resol VBUS binding - which supports a whole bunch of solar system and heating controllers from Resol, including many branded OEM versions.

Now this binding is available as beta version in the Eclipse IoT Marketplace.

To simplify the usage I worked also on the README and a GETTING_STARTED documentation.

I hope that helps to get started with the binding. If something doesn’t work as expected please directly raise a ticket on github then we can try to keep this thread here a bit more clean and more about general discussions about the binding.

Hello everybody,

I’m new to the forum and would like to thank all of you who worked on OpenHab and this Binding. As a big fan of the Resol products, I have a regulator MX with DL2 for my solar and heating system, as well as the oven in use.
Unfortunately, I’m having difficulty configuring the Thing.
No Thing is found automatically. Also, the manual create does not work.
When I enter the IP and port 7053 of the DL2 in the browser, a message appears:

  • Hello
  • Error, buffer overload, quiting …
    (or something like that)

The installation of the binding has been inconspicuous. I suspect that it is due to a setting of the DL2.
Does anyone have a tip for me? Is the port 7053 correct? I have nowhere found a way to adapt this. What does your browser show when entering the IP and port (XXX.XXX.XXX.XX: 7053)? Please let me know if you need more information about my system. I look forward to your help.

I thank you in advance.

first of all sorry for the late response. Real life and work was consuming too much from my time. Normally the port 7053 is correct, but you cannot connect to it with your browser, as it is not an HTTP based protocol, but you can open a terminal and enter
telnet aaa.bbb.ccc.ddd 7053

this should give you something like
Trying aaa.bbb.ccc.ddd…
Connected to aaa.bbb.ccc.ddd.
Escape character is ‘^]’.

and ask you for a prompt which you can terminate by QUIT
But if the autodetection of the bridge thing doesn’t work, it looks for me like an issue in the DL2 config. From the manual is seems, that there is an option to configure remote access, which you have to enable and configure the password accordingly.

Also note, that the VBUS/LAN network interface only supports one connection to the port 7053 at a time, so in case you also have configured access via (or use Resol ServiceCenter or the RPT tool at the same time) it will cause problems and I could imagine that for the DL devices it is similar.

Last but not least, I remember some issues with older firmware versions, so please check whether your DL2 is on the latest firmware from Resol and update if not.

I hope it helps, and look forward to your response.
