Multiple Garage Doors / External Limit Switches

[mboken4]

Hey Everyone, hoping to get some help on 2 main things. I am quite new to most of this so be gentle lol

I currently have a esp 32 WROOM installed in the garage with a ds18b20 sensor to monitor the freezer temperature. This is controlled via YAML file in esp home on Home Assistant.
I have 2 garage doors, 1 that is myQ Sec2.0 and 1 that is old (will need dry contact sensors)

Question 1: Is there any reason I couldn't have both garage doors connected to the esp32 wroom along with the temperature sensor? Looking at the ratdgo Yaml files, if I were to duplicate the code, change the names and pin numbers to reflect the connections, it should be able to manage both? My understanding is the Ratdgo Installer is just a simple way for people to choose and install the correct yaml file and it isn't some sort of operating system that the espXX runs on.

Question 2: How would I go about installing dry contacts. Looking at the ratdgo yaml file, it lists ports for the dry contacts and the wiring diagram images appear to simply connect to a ground port on the board. With a DIY ratdgo via the esp32 wroom, I should be able to connect them to any GPIO port, adjust the port to match in the yaml file, and I am good to go, right?

I appreciate any and all help. Feeling pretty lost.
