Guess that depends on what you mean by OTT, that is the exact kind of thing the esp32 was designed for. And it works with the esp8266 as well, you can get one for like 1.50. You will spend far more then 1.50 in time and energy designing a new board (you’ll spend more than that buying one of bart’s boards) so is the hardware overkill for the application. Sure, however it is cheaper then any alternatives. Witch means it Is practical, I would say it is OTT to spend days (probably longer if thats not what you do for a living) designing a board just so you don’t have more processing power than you need.
