Thanks man ... now it's working....

i have "the same" problem at Home Assistant
I have got only Serial Gateway with 2 temperature sensors (only for test). MySensors V2.0 in the Arduino IDE. I do the presentation:

0;255;3;0;9;Starting gateway (R-NGA-, 2.0.0)
0;255;3;0;14;Gateway startup complete.
0;255;3;0;11;Szafa
0;255;3;0;12;0.1
0;0;0;0;6;
0;1;0;0;6;
0;255;3;0;9;No registration required
0;255;3;0;9;Init complete, id=0, parent=0, distance=0, registration=1
0;0;1;0;0;0
0;0;2;0;2;
0;1;1;0;0;0
0;1;2;0;2;

HA response:

"Node 0 is unknown."
"Requesting new presentation for node 0"
"Node 0 is unknown , will not add child 0."
"Requesting new presentation for node 0"
"Node 0 is unknown , will not add child 1."
"Requesting new presentation for node 0"

I even try send this strings by arduino Serial and SoftwareSerial ..
When HA says about Requesting serial gets "0;255;3;0;19;"

0;255;3;0;9;Starting gateway (R-NGA-, 2.0.0)  //no effect on HA log
0;255;3;0;14;Gateway startup complete. //no effect on HA log
0;255;3;0;11;Szafa  // HA: 0;255;3;0;19;
0;255;3;0;12;0.1  //HA: 0;255;3;0;19;
0;0;0;0;6;  //HA: 0;255;3;0;19;
0;1;0;0;6;  //HA:  0;255;3;0;19;

I don't know, what to do... i need to connect 2 or 3 Serial Gateways with 5 sensors each GW.
