I’ve made some little progress with a serial ebus adapter.
now my ebus device list is looking like this
openhab> ebus devices

However, I’m not able to get any proper values from the bus. The only value that can be read is
Temperature, solar cylinder 1 - 15.8°C which seem to be correct.
I’m trying to read e.g. Burner hours run from the Wolf CGB-2 (Slave 08) without success
Sometimes I see in the log
2020-01-15 23:37:21.338 [DEBUG] [.csdev.ebus.command.EBusCommandUtils] - Value temp_mixer with -100 is smaller then allowed 100
Any help / ideas?
