Yes, I was talking to someone who was using a Raspberry Pi as a hot tub controller. Something a $1 ESP8266 could easily do.

Amusingly, I recently talked to someone who built a hot tub controller with an ESP32; it runs on a battery that lasts for half a year.

I received an 8 channel ESP32 board today that I’m planning to use to replace the failed ~25 year old control board that failed in my hot tub.
