Waking up from deep sleep with temperature sensor

ESPHome
1

Hi guys, in my area we have a hot spring directed to a lake. I’m trying to program my ESP32 to send me a message whenever the hot water runs.
I don’t understand how to use the deep sleep function so that it will wake up when the temperature is hot enough.
can someone help with that ?

components:
ESP32
Sonoff temperature & humidity waterproof sensor
programming on visual studio with esphome.

thanks for the help :slight_smile:

Maybe you could find a suitable temperature switch which could be connected to a wakeup_pin?
