@zrail One more Q if I may. As I plan this out I realise that there are some devices I was using on the pi that the #ESP32 doesnโt make obvious.
In order to provide some physical buttons, I had a 6-key USB keyboard like this attached. It just plugs into a USB port on the pi.
And there are remote buttons integrated into the pool that are 5V. So I had 5V going to an LED on these buttons, and I had 4 GPIOs connected to the buttons. That way, when you donโt have home assistant you can still work the controls. (My pool guy, for example, canโt login to home assistant, but he needs to be able to turn things on and off)
USB keyboard is one thing. 5V buttons are a second thing (and a 3.3V version of the buttons and LED are not an option). Is there any way to hook these things up to an ESP32? I have several. So if I need to have one ESP32 for the pool relays, and then another for the buttons and keyboard, thatโs fine.
If Iโm powering the ESP32 on the pins, can the USB port read the keyboard? Iโm a bit of a noob on all this ESP32 stuff.
