Hey,
I am getting more exited about the work done on ebus control, though also a litle lost (again). Probably it is just some silly setting, though there are so many 🙈. I really hope someone can point me in the right direction. Please let me know when more information is needed or how I can contribute improving the tool and its descriptions.
Issue
While using default settings as seen in e.g. https://github.com/christiaanderidder/brink-renovent-hru or https://github.com/dstrigl/ebusd-config-brink-renovent-excellent-300, I am not able to read/receive any useful data, besides the master and slave including successfully loading a config file to the slave and the SW version (the later just in the last phase of prepairing this question). It is very cool to see that the slave is down/unidentified just after starting the daemon, and then it find one and connects it to the config file.
After playing some with the latency (0, 10, 20, 30, 40, 50, 60, 20.000 and even 200.000 as some sugest) I noticed a transition in ERR messages. Lower values (<20) tend to present "ERR: read timeout during receive command ACK, switching to skip" while higher values (>20) tend to present "ERR: SYN received during receive command ACK, switching to ready". I do not know how to solve this issue given that other have succeded with the "default" settings on similar devices.

Notable remaks, but potentially unrelated
Excellent400 SoftwareVersion = S1.08.05 0004
Notably, this is the correct SW, though the data is assigned to an entry of the c7.csv config and not the scan.csv. The entries of the scan.csv remain:
Neither does the SW version end up in the mysterious “scan.c7” device (first point in this list)
scan.7c = ENCON; ;-;-
I do not understand what this means.
