Blynk slide gates stability

nodemcu wifi
os: iOs 14
type of server: Blynk server
Library version: 0.6.1

Hello, I’m using Blynk for open my slide gates. Gates controlled by FAAC engine and have FAAC automatic board.
This board has 2 physical ports for short opens and fully opened gates.
To this ports I plug 2x relay module, which controlled by modemcu with Blynk.
It’s works, but I have some trouble with stability.
1.sometimes gates opened itself, and I don’t know why. (Rise of the machines?)
2. Sometimes nodemcu goes down and I also don’t know the reason.
To resolved this problems think i need something like log in blynk. I tried to realise it through the terminal widget in blynk, but in this case i have problem with very often sends to blynk server. Algorithm is:
1.blynk check the state of button in app
2.if state of button == 1, send HIGH to relay pin
3. Switch off button in the app
4.send to terminal message with date, time and action (button was pushed).
Even if i use blynk.timer, all of those steps of algorithm have to done in one cycle. It’s too faster to blynk i think. Also log is useless without ip address from which recieved GET request ( i use Siri with GET request to blynk open gates) is it possible to know ip address and print it to terminal ?

i found gorgeous solution to log opened / closed gates. @Jamin already do it, many thanks!
