Well, that was a fun rabbit hole down which to fall:
After ignoring it for years, I got Home Assistant running along with ESPHome. From there, I made a bunch of over-complicated buttons and blinking LEDs - except the buttons and LEDs were in different rooms of the house.
Oh, and an ESP32 camera works alright on it. And it can send OTA firmware upgrades to all the ESP32s from a web UI, which is handy.
Also I can see the odometer and average MPG of our car on my phone and I was reminded why I hated my Logitech Harmony Hub (though it did sort of work to control my basement entertainment center made of old junk)
At some point, I might actually accomplish my goal of spying on the doorbell with an ESP32 (which was why I actually started down this path in the first place)
