Someone made this and integrated it in HA:
That was exactly the point! I have 2 Sonoff SPM 4 relay modules running everything in my shed. The issue was that without my phone I had to open the electrical box every time I wanted to turn on the watering pump or start the fan in the shed. So I built this.
It used to be an ESP8266 running Esphome but I upgraded it to an ESP32 module with Ethernet. I wanted to try the module as I plan on using it to build a PoE weather station with it.
To actually get the number of I/O ports I needed I used 4 PCF8574 modules. These are 8-pin I/O multiplexers that communicate via I2C.

I don’t know why, but I want this - labels and all - instead of a wall mounted tablet.
