Sonoff SV relay does not turn off sometimes

ESPHome
1

I am using a Sonoff SV and ESP home to control my garage door. It has worked flawlessly for 3 years with the exception of about once per week or so, the relay does not turn off. To trigger my garage door, I turn on the relay and then pause for 1/2 second and then turn it off. Sometimes the relay just stays open which requires me to have to hit the button again to turn it off. Not a but deal, but it messes with my automation, and also does not allow me to use the real button on the wall in the garage as their is not power, the LED is not lit. Should I adjust the 1/2 second pause? Has anyone else had these issues?

Here is my code for the switch.
