3. Troubleshooting

The adapter seems dead, no LED shines or blinks.

The ebus wires are reversed, try switching the wires. Don't worry, it has a protection against reversing.

The ebus logs shows [bus error] device status: unexpected enhanced byte 2

Please read quickstart section to find correct device configuration options

I often see messages like: ERR: arbitration lost, signal lost, signal acquired

It's possible that the adapter has a poor WiFi reception so it has to resend messages and the latency increases. Try to improve the signal by moving the adapter closer to the WiFi AP. You can also try to increase the ebusd latency parameter to e.g. --latency=200000.

The adapter is loosing connectivity, breaking other ebus components communication, D7 is blinking, WiFi is disappearing after connecting, devices on the bus show error status or other intermittent failures.

It's possible that ebus doesn't have enough power to supply the adapter together with all other connected devices. From version v3.0 there are options for supplying external power, see the hardware revisions section for details.

Nothing helps. I need support.

Run ebusd with --lograwdata=data --latency=2000 --log=all:debug options. Then save the log, open an issue here, describe the problem and attach the log. I'll try to help you.
