Control Liftmaster LA400 Gate Opener via HA?

See by post. I have an open source hardware design for this.

Liftmaster Gate Controller

I have created a PCB design that allows the automation of a Liftmaster gate operator in Home Assistant. I have this working on my property with two gate and it works great. I’ve made the design available on Github for anyone to use. If you have basic soldering skills you can print the PCB and solder up the board. It’s actually pretty simple. It integrates into HA using ESPHome. Enjoy.
