So, gateway works as repeater by default? I also expected that on reset, whole initial sequence should appear, not just 0;255;3;0;2;2.1.1.

Thanks. I will try with an older version. If you would share known "mix" of software working together, it would be good to start with. I mean" Arduino IDE/MySensors/Domoticz. ?

@mario64
one update information (Gateway)
when I press reset button on Arduino Nano board, I get one additional line on serial monitor:
0;255;3;0;2;2.1.1

and on domoticz HW setup screen, I get one children of node with name: S_ARDUINO_REPEATER_NODE. see screenshot:

Hi @bjacobse,

thank you for answer. I'm back to my project after e few days.
Actually, the "Accept new Hardware Devices" switch is on. I also used the "Alow for 5 minutes" button. Let me share more details:

• pls find log of Domoticz:

Hi,

I've got across similar problem. What works for you doesn't solve problem in my case.
Decreasing power to PA_LEVEL_LOW or switching to MySensors v2.2.0-rc.2 gives no positive result.

I have some experience with Arduino, but it is my first try with MySensors and Domoticz.

If someone could advice how to cope with, thank you in advance.
