#77339 I am building a weather station with a reed switch rain gauge.

The switch pulls a pin low, which calls an interrupt, that the ESP logs. This part works fine.

My power consumption is too high. So I want to use light sleep to save some power when I am not reading sensors, or sending data.

The question is: will the ESP still respond to the interrupt while it is in light sleep? I do not want to miss a rain event while the device was asleep.

Thanks,
