Esphome - esp8266 and relay

ESPHome

hello, please I have a request, I am trying to switch relays via ESP8266 via Home Assistant and ESPHome. Below is the yaml file, I have it connected to D5 and I feed the relay with a source with 5V of course. Still it won’t switch the relay for me. please see where i am doing wrong? Thank you

Enable fallback hotspot (captive portal) in case wifi connection fails

Can you share your yaml using the preformatted text option. while you are typing your post you can see </> above your typing window. This will help anyone trying to help you. Check whether your relay is high or low triggered. Some of the relays give you option to choose high or low value triggered. You may try to comment the inverted: true option during testing. If the relay works without the inverted option, you may remove it from yaml.

Post an image or link to your relay. Some relays are tricky with 3.3V input.

Remove the jumper, then connect 5V to JD-vcc leaving the vcc pin unoccupied.
On the 3-pin header connect 3.3V (VCC), Gpio14(IN1), GND.

and correct your board, whatever it is,
esp01 goesn’t have gpio14 exposed

Thank you, but here is gpio14 https://i0.wp.com/randomnerdtutorials.com/wp-content/uploads/2019/05/ESP8266-NodeMCU-kit-12-E-pinout-gpio-pin.png?w=817&quality=100&strip=all&ssl=1 on D5
