Of course it was issue on my side. My understanding was that GW baud rate in mycontroller should be baud rate of RS485. When I changed baud rate to correct value everything works well. Nod is added automatically.
But I would like to kindly ask you for next suggestion.
I plan to use one Arduino to monitor Temp, Hum and CO2. Those sensors are presented in MyController as static now.
Additionally script should control 3 relays. I added relay script from My sensors but I have no idea where I should see those relays in MyController and how to control them manually
