L293D to control an electrovalve

ESPHome
1

Hi all,

I’m try to build a system to control a valve bistable.
A valve bistable need an impulse (at leat 50ms) to open the valve, an opposite impulse to close the valve.
I’m using a L293D that works fine. Now want to show on HA a single switch that can turn on GPIO and turn off the other one. Any example?

Thanks in advance!
