Hello, first of all, I'm sorry I don't speak German. Do I get it right that this project was tested on Viessmann Vitocal 200-S ? Because I do have one, but the information and the original photos I'm reading here are bit different than what I have. I bought the CAN adapter, try to run the python3 Open3E_depictSystem.py but with 0 COB-IDs found. My setup is as follows: Vitocal 200-S recommended CAN bus adapter + raspi zero 1 the first unknown for me is where to find the CAN bus connector in my Vitocal 200-S. I can see one clearly on the main board but I'm not sure if this is the correct one. I could not find any specs in documentation about it. You all are saing that you have connected to 91 connector, but i don't have it. the second issue I have is with the SW. The python3 Open3E_depictSystem.py runs into an exception with the message "[Errno 105] No buffer space available". I managed to work around it by simply running it multiple times with lower number of COB-Ids in one run. The problem with the raspi zero 1 is that i can only have 24 opened sockets. The "close" method called on the Client is probably not working and it leaves the sockest open. Until it reached the max opened socets. So I've just run only 24 COBs, then reboot the raspi and continue with the next batch of 24 COBs. But at the ned no COB-ID responded in my case. So basically either my Vitocal 200-S is not supported. Or I have used wrong CAN connector in Viessmann board or there is some problem with the connection itself. I'm a bit lost and have no idea how to continue.
