Hello,

Great job geting this going. I went through all the steps but when I run he command to check if the collector is working, I get this:

/srv/vbus/collector/vbus-collector --delay 1 /dev/tty_resol vbus-collector v1.4.1-5-g3e53b16

System time:1088:00, Sensor1 temp:45.6C, Sensor2 temp:47.1C, Sensor3 temp:47.3C, Sensor4 temp:888.8C, Pump speed1:0%, Pump speed2:255%, Hours1:267, Hours2:65535 Segmentation fault

Then, when I try to run the service at systemd, I get this:

pi@raspberrypi:/var/log $ sudo systemctl status monitor-vbus × monitor-vbus.service - Monitor resol vbus temperatures Loaded: loaded (/etc/systemd/system/monitor-vbus.service; linked; preset: enabled) Active: failed (Result: signal) since Mon 2024-03-04 16:58:00 WET; 8s ago Duration: 42.754s Process: 1857 ExecStart=/srv/vbus/collector/vbus-collector --config /srv/vbus/collector/options.json (code=killed, signal=SEGV) Main PID: 1857 (code=killed, signal=SEGV) CPU: 51ms

Something wrong?

Hmm the data looks strange, System time should be HH:MM in 24 hour format and 1088 looks like some data is not correctly parsed. But the line is only printed if the CRC checks indicate a valid packet. It might be that your Resol devices send a different formatted packet, can you try:

/srv/vbus/collector/vbus-collector --verbose --delay 1 /dev/tty_resol

to give a more detailed output.

You can see the assumed packet format here: https://github.com/tripplet/vbus-collector/blob/master/datatypes.h

It might be not correct for your Resol device, which one are you using?

Hey Tobias,

Thanks for the quick reply. Here is the result of what you asked me to try:

As for the Resol device I am using, it is a USB DL2. This is what I got from from "lsusb", which is the same VID and PID that you had, I believe:

pi@raspberrypi:/srv/vbus/collector $ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 1fef:2018
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Regarding the RESOL device that I am connecting to, when I connected through windows, I got this information:

Looking forward to hear from you! Thanks!

Thanks for the detailed log data, I added support for the DeltaSol BS 2009 data format based on your log data. Can you update and try again?

[jolas-rui]

Worked like a charm. Thanks for you support!
