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?

Hello,
I used to use 5 nodes without any problems before(2xtemp.and 3xpir sensors). A few days ago Home assistant has an update, MYSENSORS integration has arrived. I continued using it without any problem.
I wanted to add a relay (name: relay 6) today, I uploaded the code to arduino pro mini, it was connected to the network. It did not appear in the home assistant (HA).
i rebooted HA , it is gone again. then I looked for a solution on the internet but could not find it. Self-relay appeared on the screen.
Then I sent new code to the Arduino, motion sensor, same node id (node id:6)
Motion sensor connecting to network, updating json file, but not updating in HA.
I tried to add another sensor, the result is the same, the node is not updated in HA. There are always "relay 6" on the screen.
What can I do about this, I want to add relay and led dim to mysensors.
Summary 
I cannot add a new node to HA after the update has arrived(old nodes work fine).

hello, yes, it gives an error while loading code right now (Pro mini 3.3v 1 mhz minicore bootloader).
i checked my cables 2 times. I already have a board for ISP code.!
Is there any detail picture you want? do you think the boot loader might be broken while writing
First of all, for checking purposes, i installed the blink code to pro mini 3,3V with the ISP method(arduino nano). My goal is not to use the stupid booster circuit and using arduino up to 1.8v
I added arduino ide(1.8.13) minicore.
Then i chosed;
Board: minicore->ATmega328
Clock: internal 1MHZ
BOD: 1.8V
Arduino as ISP and Ctrl + shift + U
Then Blink works at 3.3v (but a little slow) but didn't work with 2.3v to the arduino.
Then;
Board: minicore->ATmega328
Clock: internal 1MHZ
BOD: 1.8V
Arduino as ISP and burn bootloader.
blink works well at 3.3v and 2,3v but now it gives an error when uploading new code to the arduino.I haven't made any other settings.
what is missing Is the minicore method wrong?
Thank you for your help.
hi,
i am using pro mini, i installed the blink code, pro mini does not work at 2.3v. I burned minicore bootloader(1Mhz-1,98).
my purpose: running pro mini up to 1.8v and saving power.
The blink code continues to run. no longer working pro mini 2.3V. but I can't upload new code.
What can I do to use it again?
the error he gave:

I bought 5 new ones, they didn't work either. I don't understand why it doesn't work Nrf24l01
@warmaniac
hello, i am having the same problem. If there is no booster, the mysensors works(full 2xAA), but if there is a booster, it doesn't connect to the network.
I connected a capacitor to the bosteer input or output and I used 2 different booster and 2 different nrf but it didn't work.
Did you find a way to run mysesors with booster?
