Not working at all. Any hint?

[EUA]

Using OrangePi Zero + PL2303 USB cable with armbian OS. Fetched from git and compiled successfully. But can't make it work.

Boiler is : Vaillant turboMAX plus 800

ebusd --scanconfig=full -f -D -d /dev/ttyUSB0 --latency=1000 returns

root@orangepizero:~/ebusd/src# ebusd  --scanconfig=full -f -D  -d /dev/ttyUSB0 --latency=1000

I can verify that the USB to serial cable is working via sending raw signals to serial port using python:

import serial
s = serial.Serial('/dev/ttyUSB0')
w=b'\x07\x02\x00\x00\x00\x04\xc4'
s.write(w)
s.read_all()

returns me '\x08\x00\x00\x93\x0b\t\xfb\x0b'

I can also fetch data via vrDialog program using windows and the USB-to-TTL cable.

One more thing, If I reset the boiler while scanning:

2019-03-05 06:47:54.890 [bus notice] signal acquired
2019-03-05 06:47:56.034 [bus error] signal lost

What can I do more?

does ebusd --scanconfig=full -f -D -d /dev/ttyUSB0 --latency=1000 --lograwdata=bytes show any >/< entries?

Nope. No such output observed. My device has "VUW TR 242/2-5 R1" label. My device might be not compatible or old...

I made WiFi-to-Serial device and captured TCP trafic via wireshark to get communication dump of vrDIALOG/2 software. Than filtered the TCP stream. I believe you can easily diagnose if this stream is compatible with your stack. Answers from ebus start with spaces, Since queries and answers are in multiple TCP packed, dump look little weird but not hard to understand the stream I think.)

Sorry. I think this is not EBUS but X6 protocol. Thanks.

[john30]

the thermocompact seems to have a RJ-45 service connector though on the electronic board as of page 32 of the manual. this is usually eBUS, but not sure about it.

[EUA]

Yes, I use that 6P6C RJ-11 port for communicate. My signal is RS232-TTL +5v compatible. Might be commands are compatible with EBUS too but your stack doesn't work on it somehow.

One thing that I need to tell, sometime boiler doesn't respond to first commands. Look like in a kind of sleeping mode. After repeating same signal (2.nd, 3.rd or at 4.th...), than boiler responds and keep responding each commands without issue.

Anything that I can try?
