Hello Vahid_Barz,
I see in your flow that you use MQTT, you could use an MQTT switch, see here:
https://www.home-assistant.io/components/switch.mqtt/
Or what is very interesting, ESPHome, look here in the link:

greetings

is it something wrong?

- platform: mqtt
  name: "lct"
  command_topic: "lctech/cmd"
  payload_on: "relay,0,1"
  payload_off: "relay,0,0"

Hello, I am not a professional, in your configuration, everything seems to be fine. (Is “switch:” about?) If you stick to the description, there should be no problems. The correct formatting is very important !!! Did you check your configuration and restart your system?

i don’t know why

Just out of interest, if you have control over the MQTT topic, best practice is not to start with a “/”. See here for example.
