Thank you for the explanatory answer.

I added a new node(ralay id:50), again home assistant(HA) was not added. How can I send a new value from the Relay?
I tried sending data with myscontroller. the relay opens and closes. is that the right thing?

It was finally added to HA. But It seems to be disconnected from the network every time a command comes from HA.
do you think this is normal?
