Hi, I'm a beginner with ESP and I'm making an automatic irrigation system on ESP32 and I'm having a problem controlling the solenoid valve. When power is applied to the relay (OKY3030 OKYSTAR) the red LED (power) is on and the green +SW is on all the time. In Home Assistant I wrote such a simple control:
switch:
- platform: gpio
name: "Solenoid valve"
pin: GPIO26
restore_mode: ALWAYS_OFF
In the HA panel I created a button with which I should control the valve, but it is on all the time. When this button is pressed, the green LED dims slightly. The 5V power supply is from the ESP (USB-C cable connected) and the solenoid valve is powered by 12V DC. I am adding the wiring diagram as an attachment. Please help me to solve the problem. Thank you in advance for your help.
