config for nodemcuv3

[Poltavtcev]

Hello everyone. Thank you very much for the great work that has been done! I'm very excited and can't wait for it to work for me)
I am using Nodemsu3 and when I try to flash it, I get the following error:

Failed config

status_led: [source /config/esphome/DscAlarm.yaml:36]
  pin:  [source /config/esphome/DscAlarm.yaml:37]
    
    Cannot resolve pin name 'D4' for board nodemcuv3.
    number: D4 [source /config/esphome/DscAlarm.yaml:37]
    inverted: True

Please help me edit the config file for this board correctly. I'm just starting an adventure in esp.
Many thanks!

use "GPIO2" instead of D4 for the pin name:

pin: GPIO2
