Irrigation Custom Component with Custom Card

Hello, I am thinking of giving this a go, but I’m a bit concerned about loosing the connection from HA to the solenoid I am using to control my zones.

I looked for the esp_home code you mentioned, but I can’t seem to find it. Is it still available?

FYI, I’m currently using this system based on a Sonoff 4 Channel Pro R2 with ESPHome.

Looking for something a little more flexible and thinking this might be worth a try.
