WakeUp with SERIAL1

[grezco]

I would like to put the MKR on sleep mode until a character arrives on SERIAL1 (pin 13-14). Do you think it's possible with ArduinoLowPower Library ?

Probably but you would need to look more closely at the sercom module in the SAMD21 datasheet. I recently enabled wake from sleep when there is an I2C slave address match by setting the RUNSTDBY bit in the CTRL register.
