Wake up ESP32 from Light sleep using photoresistor

[peetman]

To save energy I put the ESP32 in Light sleep mode after some minutes. Then I have a photoresistor that detects when a light is turned on and it should wake up the ESP32.

touchAttachInterrupt(READ_VALUE, loop, THRESHOLD);
esp_sleep_enable_touchpad_wakeup;

I've tried the above code, but found out that the touchAttachInterrupt wakes up when the READ_VALUE is below THRESHOLD, but I want to wake up when READ_VALUE is above the THRESHOLD.

Have you ever found a solution?
